Mikvanar (04/02/2012)

this is a piece of wood I'm sorry this wood over here is the out it's going to be the outside of the wall and this piece of wood is the inside of the wall and the cement is poured between these two boards with this rebar metal rebar in in between after it all dries you cannot see the rebar it's in the it's in the concrete but the normal thing to do when you have this is to put pins across this way go straight through this wall and through that wall and will Stoppers at the end of the pins which stop the wall from expanding under the weight but you cannot do that for mik because it's going to rust and leak so therefore you have to support you have to make sure that they shouldn't be pushed out by putting in these boards over here which go all the way down that's um boards go this way and Boards go that way because here's the other here is the other wall with a rebar in it in order to make sure that it doesn't get um the weight of this concrete doesn't push it out okay let's go to the next picture yeah okay so this is you can see that these um boards that keep them separate this one and and these are all the way down to the bottom of the mikra because otherwise the the weight of the concrete can actually split the board in half okay now you may wondering what these chains are doing over here these chains okay the answer to that question is is that these um outside boards there's no problem with these outside boards in going down to the floor to the Earth here is the rebar but the inside that's this part this inside cannot go down to the floor because there's supposed to be a floor under it so therefore these this board is doesn't hit the floor so how does it get suspended midair it's about a foot above the Earth underneath so the they hang with chains and they pour concrete here and and concrete here and all the way around over here there's the re the green rebar and it's um and the concrete goes under the it it goes under this board this board which is the inside of the extremity of the wall of the mikah goes under it and forms the floor that's in order to pour it all at once yes because the mikah has to be poured at one time cuz you first pour the floor and then you pour the walls eventually it it dry cement does not um adhere properly to the cement which we put on top and eventually it's going to leak between the place where the floor wi and where the wall is it's all be H at one po okay another angle okay so now over here this over here is insulation there's usually about 2T two in rather of foam insulation which is put in there so that when you when you warm up the Mikvah that the heat should not dissipate into the Earth around it and the cold from uh outside like in the winter should not come and cool off the water in the mkah so this is pretty important to do this that it there should be a foam over there to protect to protect the heat of the M okay again Rosa if you have a question feel free to chat the question on the on the um on the screen the question is is that insulation on the outer wall or on the inner wall so this insulation here where is this in reference to where they going to pour the concrete the insulation is usually put outside the outer wall between the outer wall and the Earth that's the normal place to so where but it looks like they're pouring the concrete over here um and must I think it's um maybe maybe no see what okay let me say something there's two ways how there's many ways how to build a mik there are some people people who are of the opinion that you should first make a cradle of concrete and then pour the mikra inside this cradle now I'm not a f in favor of that because I think it's a waste of money and not only is it waste of money but it could cause many many problems because if there's a leak in the Mikvah and you and the outside is exposed let's say you can go down to the basement and um the M on the first FL Flor so it goes into the basement and you can see from the basement if it has a leak if you know that um if if you only have one container where the water is in you can see where it's leaking it'll leak to the outside but if you have one inside of the other there's no way you can tell and it could cause a lot of problems so the um and this seems to be the outer cradle which they made and they're going to pour a m inside this so I said I'm not a of this I I'm really against it but besides the fact that it's I think it's cost you about $30,000 extra which is a waste of money okay so here um this is what it looks like from on top and everything is being hung this inside the inside container which is going to the the concrete is going to be around it not in it has to be hung so that the cement could get underneath this is a picture the green is the rebar there's a halic discussion in the posum about this rebar it's made out of metal and the um the mik is not supposed to T now theud which who says that um that if it's that if this Reba is meant to be used with something which is attached to the ground it is not so even though that's everyone agrees with that but the question is when they make this rebar they don't know where it's going to be used and it may be used inside a ship which is not attached to the ground so the nuda says that when the person makes it he makes it whatever the customer wants use it for if the cust wants to use to use it with something which is attached to the ground so then um it will be it will be um not makab Tuma we rely on that and I spoke to the S Title about putting in this rebar into mik of course it was some time ago uh maybe um 40 50 years ago and and um he said that he made a Mikvah and he did not put in any any um re into his Mikvah and actually it started cracking falling apart after 7even years and uh he said so I made another M I did it again and I didn't put rebba in again so we so I I was there with Epstein were there to speak to mik we're making Lakewood is not the current mikush they have now and um he said it was it was on Route 9 with a lot of trucks and the engineers said that there's so much vibration going on that from these heavy trucks that it won't last without any rebar and he said so put in the rebar I said I wrote a Chu on it that it's not there's no problem and it's also based on this n Huda and it seems to be pretty much accepted today there's a new technology available that they put fiberglass um pieces fibers into the concrete and then rebar is not necessary he says uh what about fiber mesh is that what was talking about no it's not a fiber mesh it's a fiber the FI they are um glass fibers fiberg glass and um their fibers which keep the thing together just like where the they put straw into the um into the cement which the piece of straw kept it together so this the fiberglass pieces which keep it together and it's uh seems to work okay it's not necessary to put in any rebar but there's no problem with it if you do it getting back to this um piece of insulation you could see here that it's clearly on the this is the isn't this the inside yes but I I'm pretty confident that this inside is put on the um it was put on the Cradle not on the actual mikah okay I don't have a problem if you put it on the inside but we're going to have a wall here and this is going to be outside of the wall if you pour in if you pour in the concrete over here if this is the inside of the Mikvah so then and this fiberglass this um instulation is going the outside of it okay so re saying that's still the outside okay it'll be on the outside either way okay okay so this is just another picture of how they set it up okay let's go to the next picture okay I don't think there's anything important over here we didn't don't already okay so now here this is going to be a wall over here is going to be the M we're looking from the side we're looking this picture we're looking from the top and um this is a spacer which is put in a spacer which is put in to make sure that this is that the between the two pieces of wood that stays spaced right however when they actually pour the mikah they take these spaces out because once you have the concrete in it it will push the will push this piece of wood as far as it can and it can't do it too hard it can't too far because we have these pieces of wood holding it in so this is there just for the initial construction it's it's important that this rebar does not touch the outside of the this is the inside of the mikah is going to be the inside of the mikah it should not this should be not touching because it does touch then it's actually going to hold back the water and so and it's it's going to get rusty and it's going to make big problems because it's Cod sooner or later so therefore it's important it doesn't touch the outside and they know that even if it wouldn't be a mik they don't put it towards the outside it's very shy workmanship and um it wouldn't be done okay now over here when they set up the when they set up this Bas I'm assume is the Bas there are two pipes here one pipe here and one pipe here now after they pour the concrete over over here it's going to be poured over here and go down they're going to be two pipes that go all the way through the wall now one of them will go to the there's probably going to be two bars over here one will go to be the Asaka one's going to go to the Z we going to speak more about that in in in the future but the um they have to be put in before you pour cuz otherwise you're going to have to drill holes through the through the wall if you drill Hool through the wall you sh you shake the wall and can cause cracks in the wall um and you might hit the metal bar metal bars of the rebars going through this way you know you put them in before and there's there's no problem with them so it's important to have them in there before you pour the you pour it okay this is just a closeup of what we saw before okay here we see the the ra M okay we blurred it out because we we uh okay we didn't uh want it to be uh public necessarily that's fine so this may be the same um idea that these are the pipes that going to go through the this is going to the wall is going to be from here to here and the um so this ra is making sure that everything's done is done properly and um these again are spaces cuz the wall probably will go to the very top till here and um okay go for all right the the size of these pipes should be according to the it has to be which is about a little bit more than 2 in um you could use a 2 and 1/2 in pipe if you want typically they use a 3in pipe or the bich is mid on a 4in pipe um so the says that the reason why this T says that the reason that they are Ma on 4in pipe is that when you fill up the Mika through these pipes that it should be able to fill up real fast so they make bigger pipes but it's not a really h on um on how big it is once it is over the shear of which I said is about 2 and a/4 in diameter okay so those pipes that I was me talking about before they go from the to the from the to the B and from the to the B it's important when you put in these pipes that they should be level the pipes should be exactly level because if they're going to be higher on the side of the bur and low on the side of B so then or let's let's first take the other case it's high on the side of the Bas of and lower on the side of the B so you when you're going to if you have a 4in pipe or 3-in pipe you don't have to fill the pipe all the way to get the shear of the area of and it's going to be faulty way of determining if it's enough or not because you're going to be done by the side that you see but the other side may be less than the shear fero or vice versa so therefore it's important that they should be put in EXA L horizontally now here there people who are examining the roof and um the um it's important that the roof should be set up in such a way that the water water prob is going to drain off this way or um I'm not sure what this line is that's just the picture it's just the picture okay but they're probably drain off over here and the water collection for the initial rain water is very crucial that they should not be any problems I recently was involved with the mikah and I said I want to go up on the roof so they said why you want to go up on the roof I said um I know you never know what you're going to find anyway I found a wallet up there um with someone's driving license in it but that wasn't the issue what I did find over there was there was a garbage can lid a metal garbage can lid which own threw up over there on the roof which was upside down and could actually hold the water and then it it fills up with water and then it would it would spill over I don't know because that's the that as long as you to to to to fill it it would be okay and here no one even knew it was there but it's not one rule we should know by mik it's important to make a mikah that as many people as possible should be happy with it even though that maybe we convinced that Allah is that some of these humas are not necessary but we'll try to make as many people happy as possible one of the mikas made for the so there are all kinds of people in the to make one that I am not sure if it is practical or possible but the it definitely can be made according to the sh of theim the rubub of the Pim could made without any problem okay so now here is the here we're dealing with with this roof now if there are indentations in the roof and this is the place where the rubbers were were um glued together um if there are places where the water will stay after a rain doesn't matter there's no on something which is the the problem first starts when the water comes over here and it goes off into the gutter which was not which was cover that first you made into a and then you attached it doesn't help it's only if you first if you and this was a building and afterwards you made an indentation then it's then it's a then it's kosher that's why otherwise every mik will be posle every mik is a k that's when you pour it and you um and uh you you pour it and it doesn't matter if now water that's what every m is now the truth is that the maram in his first CH said that a make out of cement and concrete is possible but no was that and if you're going to go with that I think it was later but um if you go go without I don't think there's going to be any Kos all in America maybe not in the world okay so this is a vent and this is not a problem because it's not M any even even though that this is a k if you take this piece and put it upside down but it's not put in a way that you can moule it all the water that would the r that would come on here would go down here go and eventually go on to the the roof of the house the fact that over here there's a ledge that goes up which is intended to cause the water to go down at this end is not a problem because this was built on after the house was there so it's which is not it's not a problem anyway it's not meant to accept anything to it's meant to in to uh get the water to go down this way instead of going off of this side and therefore it's not a problem whatsoever here's a question how does one deter determine Ro in terms of pleasing everyone can different bers be built within one Mikvah in accordance with different Shas one B being another Ash all right so let me say something about andas there is no question that both theik which isab that means in the B there's a underneath it is kasha and there's no question that if you have bar next to the B that is kasha there's no question about whether if you have just a that it is kasha and there's no question but there is a question if you just have a whether that's the question really is more of a practical question the um old mikas used to have a hashak and used to pour the water straight into the Bas ATA and when it when it hit the when the water went above the hole between the and the B it was a mik there was a problem over here that if the mikah tenant did not fill it up till till above the hole the M water is just plain bath water and it would not be koser now especially if the woman wants to be toille is a short woman maybe the M woman has Rus on her not to make the water too high so she'll make it a little bit lower beneath the hole so in order that shouldn't happen they made everything with all the water has to go through a mikah and by making it go through a mikah it becomes mikah water and then it doesn't matter if it doesn't go up to the hole um according to the strict now the was very much against theik so so so so the um wasab the bar is under the place where the um people are to so this under the place people to it's impossible not to fill it up to theole because all the water is going to be in it has to be in the bottom mikah before it can be in the top mikah so so there may be a problem that person's to will put their foot over the hole and then it won't be connected so they uh even though would be anyway so they make two holes that far enough apart from each other that you can't put one foot on one foot on the other because they're too far upon so however from a construction point of view it is not so simple to make a bur gab bur and it's also the bottom bur the dirt in the M usually flows to the bottom so after a while if you have a bur under your bar with two holes which are wide according to the bab um you actually after a while get it's it starts to get all full of dirt and when it has when you have a foot of dirt in it which is in M which is used um frequently it's it's not after a year's time it can get quite afterwards you may not have the sheer of water anymore in the bottom in the bottom so as opposed to a z bir which keeps getting cleaned out every time you put in fresh water and anything will be in it gets washed out so then you don't have that much of a problem besides which barab bar is very difficult to clean out the bar on the bottom it is much easier to do that if you have a separate ins so these are practical considerations was very much against the because not because it wasn't kaser it's for sure kaser but he said that if you have standing water in a bar you change the water in the the mikah but the bir stands there after while going to get water bugs and if there's water bugs women get afraid of them they won't come to the mkah they want to they're scared of the bugs so it's a it's a deterrent for people to come to MK that's why it was against it but not there question the if you just have a there areas in theim that say that you should always have 40 so of rain water in the Mikvah and if you have Z keeps getting washed out all the time and after a while since you changeed the water in the B you don't have anymore any 40 of rain water so that's why many have besides is not like the and so we're not but if today they um the custom is to be for that and therefore we make two bar andak theak doesn't change too much and as z bar changes all the time okay now this is another manifestation of what we saw before but over here is a drain a drain sticks up from the floor from the from the from the the floor of the roof and this next picture can see okay this is a closeup of the same picture and um they're probably is a drain over here also one of the drains goes to the mikah when they want to fill it with rain water and one of them probably goes to the drain in the street and um and these leaves are around it because they've been washed with with the water so you have to be careful that um when they want to use the um rainwater to fill the mikah they have to plug up this they have to plug up the this drain over here that has all the leaves on it and that forces the water to go down this drain which is the um which is uh um going to be the koser Wat used for the MK doesn't is is isn't this looks like some sort of cap to a yes it's a cap this one also has a cap the cap is there to catch the S like some sort of exhaust no no no this is uh this stops the leaves from going down into the pipe and this here there's the same thing but this is lower and it has the same thing to hold back the leaves that's why all the leav are here and they didn't go down the pipe but the um oh you can't see the cover over here but if they instead of um if they put a stopper in this in in this hole then the water will be forced into this one and that's what they want use when they fill the M CU most of the time you don't want the rain water you don't need the rain water it's only the beginning and if you want to change the rain water you need it uh some pay to do it every year or what or so and that's what this setup is for okay now here there's something else you see all these uh wooden um these wooden beams what is what are they doing over here these wooden beams so this also has to do with construction when they pour the concrete the concrete is so heavy it's much heavier than the wood wood floats in in water it pushes up the the concrete under the wood pushes the wood up so in order should push it up they have to put beams on top to keep it to keep everything down in place same this over here is uh basically the same I the same idea okay here we're looking from on top and um I'm not sure exactly what they're doing here they must be doing some work someone has a lantern and he's looking down okay I see what what they're doing over here this pipe over here this is a pipe this is a pipe and this pipe is put in it goes into the mikah um this is um this is in the wall this is a pipe which is in the wall and the purpose of this pipe is of one or two things it's either an exhaust pipe to pull the water out of the Mikvah um with a pump attached to the the end of this whereever it's going to end up and when they want to empty the MK they do that the the early mkar that were made before World War II they had a drain in them on the bottom of the mid to drain out the water however a drain comes with a lot of problems because you have to when you use the M you have to plug up the drain now you have to plug up the drain such a way that no water should leak out cuz if water leaks out there's a you can't you have to can only you can't be T in running water so if it lies out of the dra drain stopper which after a while gets worn out by putting it in putting it out so it's not going to fit tight and the water's going to leak and so therefore it's not done anymore today all mcars are emptied by pumping out the water so the pump if it's uh the the pump the water goes up above the above the walls of the of the mik and goes out to a drain somewhere so it can't leak because it's in a if the drains on the bottom the pressure of the water will push water out into the drain pipe but it can't push it up higher than the level of the water so that's much safer okay now this pipe over here this um black pipe is um I believe a pipe which they Ed to pump in the concrete they pump in the concrete because the truck couldn't get to the building it it just can go to the outside of the building then they have these pipes and they and they um pump it in these pipes are tremendously heavy because a concrete wasts so much you need sometimes two three people to hold it three three strong people because of the weight of this pipe well that's when they want to pour in the concrete like they pouring the concrete over here in this picture um show I want to go back to the picture before okay over um no there there a yes this picture okay now this we have a question how thick is the wall that there typically the wall is somewhere between 10 and 12 in that is the wall of of the M itself now over here I believe that this over here is a vibrator there's a pipe that comes out of it and all it does it vibrates when they put in the when they pour in the cement they have to make sure that there's no air that is trapped in the cement which is typical that happens when it plops down down into the place so there's air there and if there's air it um it's going to um cause a after it dries there'll be it won't be water tight so it has to be vibrated properly what's the next picture okay now over here um's go next all right this is the pipe he's filling yeah this is the pipe which is is pouring out the concrete this is the pipe which from which the concrete comes out this is the concrete coming out over here this is the end of the this is the end of the pipe um what they filling it okay this is just on the top this the top view of the um concrete okay this over here is one of those pipes of the theak pipes that goes from this from this side to the other side to connect it that um when the M will be full okay now I believe that he's holding but he's holding it I believe that this the vibrator it's has a long um pipe to it so could be um somewhere between 10 and 20 ft and it has to be properly vibrated if it's going to be um if it's going to be water time okay seems to be showing the level where he wants it full well yes see this this R over here is saying that the that the it should be till the top top of this board and that's typically how it is done is it filled to the top okay this is just a showing getting it's getting higher up to the top as I said it all has to be poured one one time it's called a unilateral uh not unilateral it's called a I forgot the lotion but there's a certain lotion that it has to be a PO we pour it one time okay here we're getting to the top already and and um this uh holding to the pipe that is pouring out the conrete okay go ahead it says monolithic monolithic right that's the word thank you the word is monolithic po that's the end of that one that's the end of that series of pictures we come to another uh series of pictures where mikah was knocked down and rebuil okay so this mikah was um as a sign on the outside Mikvah so I'm not sure um in the in in Baltimore I was against putting sign mikah on the outside because I just think that it's uh it's imitation for people to uh um make trouble so it's better if it's it's quiet it's a nondescript it's building it's just a door it looks like a house and no one should shouldn't attract any attention Okay now this over here I believe is the Cradle which they pour because the floor is already poured over here and this is a no no you don't pour you don't pour a mi like that because when you put the the walls up like this it's going to it's going to leak here on on the floor now even though that they put something over here which may be made out of rubber as as a way to insulate it to stop the water from going through it's not going to work on a long time on a long time situation so they want to put this whole thing up and then after they they're finished they pour the mikah inside in here they're going to make they're going to make B inside this is just to hold everything in place so that it's strong long as I said I'm not AUST of this so this is not the actual floor of the mikah this is not the floor of M floor mik is going to put on top of this okay now I believe that this is proba looks like the same thing and this is where they already put up the boards over here on this floor to pour in these walls which are going to be the Cradle walls and the actual mik over here is going to be poured inside this space now let me show you also that these boards over here are are there they don't want to put any pins even in this outside one they have these boards over here to hold them to hold them up so the pressure of the concrete should not push push these walls down okay so now over here you can see where I was talking about that this is the outside wall of the cradle and this is the inside wall of the Mika which they're pour no this is just boards these boards they haven't poured it yet they're they're going to pour it um um at a later later date so we have two questions here what is the problem with the Cradle why doesn't the r uh I I don't like the Cradle first of all because it waste of money cuz I don't think it it acces anything and second of all I think that it is a problem I've had this problem in had a CU if there is a leak in in the wall of the Mikvah and very often this is a very often this part is exposed in the basement of the building so in other words the the m is on the first floor the ground floor and in the basement you can see the walls and if there be any leak you could see where the leak would be on the outside wall CU it's going to leak to the outside but so where you see a leak you know where it fix it but if you put into a cradle the water gets between the mikah wall and the Cradle wall and it's going to come out someplace in the Cradle wall any place not necessarily the place where the leak is and so it's very hard to find the leak if that sort of thing happens okay checking the reliability of the mik does one have to inquire whether the raak himself was present at the pouring of the concrete or is there a certain monus that is attributable to lay or other Representatives present at that time that can attest that the pouring was done properly the the does not have to be poured you just have to have it and you can come and see it if you if you look at it you test it to make sure it doesn't leak it doesn't matter how it was poured this would be in contradistinction to the the collecting of the water though yeah that would be even when you collect the water to the way it's set up set has to be uh carefully scrutinize to make sure it's done properly but once the once it's set up you don't have to be there when what actually comes in okay um okay I assume that this is a k mik it looks like it's on the outside of a building it doesn't look by it shape that it because if if if this is a doorway if this is the doorway so then this is not very deep this m it looks like a k mik and uh so don't say anything wrong these marks that you see on the outside the these these marks that you see on the outside they are just from the boards which they put up so they left marks there but this is a solid wall and there's absolutely no problem with this okay so here this is the SI this is the side of a mikah building and this hole I'm assuming is there so this is the place through which the rain water which is coming off the roof which is all the way up here it's going to come through and it's going to go through a pipe over here into the virus or wherever you want to store the water okay so this over here is the they're using metal studs this is the the newest craze they used to use wooden 2x4s now these metal ones must be cheaper no the no sh with that they're definitely um even even though the the water is going to come off the roof which is supported by these metal studs it does not matter it is they're not and there's no problem I wasin once and he was he was so upset I've never seen upset like that before so I asked him like what was the problem he said they made a m and they were not to put any nails in the roof because the water's going to come off the roof and it didn't want it be supported with something he was so upset that such say the person could be something that makes no sense whatsoever not that the nails are um are Tuma not that the doesn't make it true of him and the whole thing was not necessary and uh so I'm just saying that these studs even these wood metal studs even though they're holding up the roof doesn't matter there's okay the next set of um pictures where is about leaking Mikvah since we're on the topic of that okay so this was a mikra where evidently the cement was not um vibrated properly and I was talking about the a holes these over here are all air holes in the in the concrete and when they've actually uh put it put water in it to test it to see if it's waterproof the water came gushing out over here not just trickling out actually gushing out in a in a in a poor um because it went through the air holes that were there in the in the wall okay so this is uh this is um over here is where the water was coming out it really came out b um because because of these holes there was little holes in the cement because the Builder said that now we have new cement we should don't have to vibrate he doesn't need vibration I in the end I I said look we got to what he doesn't need it do it so then he did it but he didn't do it fast enough until the bottom part over here still over here he did it later but he didn't get to the bottom of it uh in this I go back yes please in this picture you can see over here all the water on the bottom which had leaked out from this uh from the this W okay um can you a little smaller little smaller yes so this over here can you see the over here this was the hole which they cut out in that wall of the Mikvah which was leaking so they cut out all this concrete the with the holes in it and this is the rebar which was in the wall and they put down two piece rubber over here went all the way around and around the top and put one here and one there in order to that after they fill this with special type of concrete which expands after it dries as it dries and therefore make the tightest fit possible um but still felt they need this rub in there to stop the to stop the leak so the um uh this happened some time ago and it seems that um it's holding this is this the same this is the same oh maybe it's not the same but it's it's the uh they cut this out from the wall of the mikah in order to repair it so they have a special type of which expands as it dries and therefore it makes a pretty tight fit a barrel which is made out of wood how does it get how do you get it water tide it's made out of a l pieces of wood but the wood when it gets wet it expands and they expands so much that it presses against the other wood in such a way that it becomes water Ty and this was another place where they had to get out the in in the same construction site they had to get out the some of the cement which was leaking and the um they didn't have to go all the way through it seems that part of it was was pretty tight but it did they went halfway through because of these s holes which they had well when they saw that when they saw that they went halfway through past the rebar they saw this part looked pretty good and this is still another place where they did that where they had to go all the way through and there you have the pieces of rubber again over here which they put in it's a special type of rubber and um this rubber they they put that in to stop it from leaking make a little bigger okay so this is the the same the same big when they repaired it they had to make sure that the um part they patched up would be um would not would be pressed against the mik walls they put up all this whole Contraption over here to make sure that when they fill with concrete that it will not um fall out or be loose but it should be tight in the place where it was um where it was patched it looks like there's a box over here they didn't just fill the space that was dug out they they filled more um no they put a special box over there which um would not just wood there's something in there but the actual wall was were flat after they finished could R address how much mikah has to leak in order to be a problem and how do how does one know okay there's two things once M starts leaking no matter how small the leak is leaks have a tendency to get worse and not better um so which is brought down that um if it it leaks less than 2 in in 24 hours it's considered in the Caris but not everyone agrees with that but that's a pretty much an accepted in most places because you can't see at the time you fell you can't see that it's leaking it's only after 24 hours you see that leak but if it's more than that then it's puzzle and if someone is that the m is leaking test it how how can they tell where it's leaking from how can I tell when it's leaking okay so there's the oldfashioned way to tell how mik's leaking like this you take a toothpick and you put it in the middle of the water you come back the next day and you take a look on which by which wall the toothpick is the toothpick is going to is going to go to the wall where the leak is now you don't know where in the wall the leak is is near the top is it near the bottom well you fill it up halfway and you put it in the middle again if it doesn't go to the side evidently the leak is in the in between the top and the until where you filled it so you filled up 3/4 and try it again and that's the way how you get to where the leak is if it doesn't move at all the leak is in the in the floor straight in the floor and what's the new way you have say that's the old way that's the old that's the old way how you tell how you tell so the um there there once that had a leak and we got an engineer to fix it and he says there's no way you can tell where it's leaking so I told him the toothpick thing he was very aspell from that he he saw the amson it he said sounds good sounds good so we don't need a new way okay how often does a Mikvah need to be checked for leaks we don't assume there's a leak unless you uh unless all of a sudden the the water is not on the same level one day as the day before should someone be looking for that um it's important that the M be koser if it is if it is leaking let's say it leaks a half an inch now the question is the half an inch leak because of evaporation or is actually a leak so the way to test that is this is the old way to test it is you fill the Mi to a certain point and then you make a mark on where to how much you fill it and you take a bucket of water and you fill it to a certain point and you leave the bucket in the MRA room if the bucket and the mikra both lose the same amount of water then you know it's evaporation but if it's only mik loses it and not the and not the bucket so then you know that it's problem in the okay so now this is a there is like this that the it says in the in the if all the water it comes from and you pour it over the ground and and from the ground it went to the mikah but it originally was in a so was so it's but if was rather then it is but m is M so this says it should be a wi the says has to be at least three long the water runs over the three but what's typical is that you have a a pipe that ends up into the when when the pipe is when the W is running it jumps over it doesn't hit the ground right away and first hits the ground after a few inches so the part that actually hits the ground has to be at least three three now included is is this is all included if the water hits it and and and this even though it goes around the corner it doesn't matter it doesn't have to be straight and here it goes into a pipe which goes into the bar this over here is a cover on the bar it's a plastic cover and it's cut out uh over here and when you pick up this cover this Remains the this half pipe the the significance of this half pipe um I'm going to speak about some later over here this over here is a plexiglass piece of flat piece of plexiglass which is put into two IND indentations on the side of this ham there's another one over here here's an indentation and there's another one on this side and it is to direct the water if the water comes in over here it can't flow over here to the next bar or to wherever else is going to go is forced to go down over here and and into this pipe which goes into the bar okay so here here in this case here's an indentation and um piece of Plex of glass could be put in over here there's also one over here if you want to fill up this bar so then you put in the plexiglass over here and it automatically go into into this part I'm not sure exactly why this plastic is over here I guess doing con instruction um this says should be it should be Kaka which is really it has to be absorbed to able to absorb the the water as opposed to the mikah itself this is a wall of the mikah over here this this wall and and this is also part of the wall that you don't want it um to to absorb water you want it to be as waterproof as possible so the way you do this is you put more sand into the mix so usually the if if it's half sand now you make it 3/4 sand and then it'll absorb the water now aric um the farm he um held that this kak FL has to be connected to the ground to the the natural ground because he says says that there's veins in the ground and you want that this water should be connected to all the veins of the water in the ground in order that it becomes what it was once is not sh anymore there are even though if you make the whole it's not it's only it is even if you took the whole as long as made on the water even though was one sh him it makes it not Shu him anymore he says this picture illustrates an error that the Builder made the previous picture shows that the Builder had put a cement slurry over the loose Mix Concrete to make it look smoother we had to have them remove the slurry so here in this picture they removed it okay okay here we can see this is leaking this is rusting okay so here we I'm not sure exactly where this is but here we have a rust spot um in the concrete there's something wrong over here there must have been it could have been a nail which when they put up the boards on the outside to when they put the forms they put a nail and the nail protruded from the form into place where the concrete is so then it maybe it enter the concrete maybe an inch one half Ines not significant there wouldn't be any problem but if it's something from the rebar inside that turn to the outside that's much more of a serious problem leaking not okay so they they try to save money scre and they put in screws they made in China where the stainless steel in China is very often or they didn't bother because thing still screws this looks good before you put in the water but then they start to rust so this really it wouldn't Poss make these screws not that deep but it discolors the the wall and discol colors maybe in the water it's not it's not AB now this over here looks like a exhaust pipe that um that pulls the water out of the m b fi when you want to change the water um typically this is put into the wall but it doesn't have to put in the wall just just put into the wall for beauty uh purposes but not for any Hala purposes 100% ction um but it would look nicer if you didn't have anything on the walls outside the walls okay so let me explain what this is the this is the top of the mro wall this over here is the which is on top and the water is coming out from the roof down this pipe and this over here is a pipe which has is open on on three sides it was open here it was open here it was open over there where it's attached to the other pipe now the reason why they used this pipe this type and didn't use just an the water comes down here go flows down over here and then it goes into this um half pipe and goes down into into the m so let me first explain the Lums behind this P they could have used a regular bend a regular pipe with a bend that will go from this straight direction to this direction is uh that type of pipe really is form of a CLE even though it's not being used as a CLE over here but if you would take it off and hold it with the two sides towards the top the two ends it actually hold water this type of pipe that you this PPE of fixture this piece which has three places where the where is open to the outside there's no way that you can hold it it would hold any water and so that's why this is why they use that even though this end they're not using at all they're not using for any the word only goes out that now when it comes over here they could let it just drip into the mikah but there's a sha with that because this mikah has a it has it goes from this bar into the mikah so there's a hole on the other side of this wall there's a hole on the other side this this one whichever W it will be there's a hole and the water will go down over here and when it fills up it's going to go through the hole into the B now if if that happens says that this water which flows down here and goes over here into into the hole into whichever wall the hole is is really not standing water it is water which is flowing and has to have standing water and I'll be running water that's problem we is it just running water so in order to get around that problem you force the water over here so when it goes in go down beneath the hole at this point beneath the hole it is not flowing it's only flowing above the hole or at the place the hole the hole is not going it becomes M Water this place and then if it goes up again later and starts moving it's not a problem now really what we're dealing with this water is coming from the roof it's not really such a problem but if for some reason they want to put in regular water once you have saw once you have 40 saw rather you can put in regular water over here put a hose in over here and the water will flow then it will only become koser Mel water if it actually mixes with this mckel water beneath the place where the hole is and then when it runs out it all becomes water through the 40 so which is already in this place thing that would City go here one no initially initially you have have 47 rain water once you have that and let's say it holds 80 C and the water cell is going down for whatever reason evaporation some way so you want to fill it not not always practical rain water number one because rain water very often is dirty because it comes from the roof and number two is sometimes in summer doesn't rain for a couple of months so then you can actually go with regular water has to go to and then if go down over here then it will become MC Water by being in the M okay okay so this is this shows um just different angle the same thing to show that it's open all over here it is at this point the water would run down over here this it goes It goes down there a slope it goes in here and goes down this pipe as I I suggested it whates the KE same okay now here's an interesting thing so the whoever made this mikra this looks like mik so the water comes down over here and this is a k mikah maybe it's not accessible to the public and the water goes through this hole um and fills up over here and this is the place where the people use now for some reason the bu did not listen to the instructions and he made this host uh it's only 1/2 in pipe and it has to be at least two and4 inch pipe 3 in pipe but he didn't have the pipe handy or whatever reason I don't know why he didn't do it so now after he's finished um he said what should I do I said well you have two choices either drill this out this pipe and put in a 3in pip but you should know if you do that you might be drilling into the rebars are to know exactly where it is or make some more holes make these holes and if all together they have the so then it also be it doesn't have to the first doesn't have to just one hole is that the only make for the RO has seen like that pretty much pretty much they only make uhhuh but why didn't they just make one other hole a bigger hole cuz um the one who did it his drill that he had with him was only made that size hole he's asking are those holes too high no the holes have to be lower than the top of this hole cuz as it is we figured out on paper exactly how many holes you had to make this hole um the water has to be filled at least here and all those holes are beneath that benath that space okay we're going to get to some of the questions that you're asking in a minute let's just get through these through these pictures here okay this is an up a closeup of closeup yes the same thing same idea just to give you the perspective this is the mik from the looking at the outside okay okay this is from the outside where the water's coming from from the roof to this C but here again that this is a t was used for that reason U was not a was not a Bend of the PIP CU you're not supposed to use beds the pipes now you have to be very careful over here this piece over here puts two pipes together um when you do that you have to be very careful that there's no space between the two pipes that can hold water so what typically is done that you put you smear the inside with the coron compound to make sure it's all smooth inside and the two pipes because this is the third this is the third pipe this one that keeps these this one together with this this one so they they put Cork and comound inside to make sure there's no place where the water can gather what if a pipe has a crack is's asking if it has a crack um it is if the crack goes all the way through the pipe it's even more prusher than if it didn't have a crack CU now for sure it can't hold water okay so this is really what happened over here that this water is coming from from the roof um this is was the normal drain pipe which went out into a parking lot and was connected over here now they disconnected it over here this is pipe is not connected in order they could connect this pipe with this T this is a t on the top and water went over here it's connected to the SE pipe and here was connected to the pipe connection was saw before and from here it goes into the building into the into the M now over here this is the uh this is the the uh drain pipe no it's called g g this is a g it's a metal G but if you can notice that it's on a slight angle in order that the water they make it ESP a slight angle in order that the water should go down this through this hole over here in the B to go through all the way down here okay so here you can see better a closeup this is the this is the uh T and over here is the place where there was a hole in the pipe now you can't see from over here but at the end of the pipe they took off the cap because if it has a cap so then actually could hold some water from past this place is going at an angle downwards so actually can hold water over here so should not be able to hold water this C was taken off any water that would not go down through this hole would just go into the ground they're asking if the the roof permits metal gutters I have no problem with permitting metal gutters um the the problem metal gutters is not that it is a it's not that it become because we took care not become because took off this end over here so it's not a CLE that can hold water the question is it's tum and when you make a m the water has to come in it has to come in through not through T So number one it goes through this passing pipe which is not the doesn't say PL pipes talks about metal pipes and then even it would be the bottom before it goes into into the into the actual B it go through over some concrete that's enough that it's not considered so you you can start a with the snow um because snow does not become but you can't just take the snow and put it into the M you have to put it on a board outside the M let it slide in so it should be is without any problems as a matter of fact all the old before that Plastics everyone was made of metals no one had any problems with it now if they would if if they would design a Mah I would put it in TS because um people feel more comfortable with them but from standpoint there's no problem this was there before they built the M this is for K yes okay we have some questions here um um um go back a little bit okay the question again about koses for leaks if we are not Kish for leaks is it ever necessary to check at all going back to that issue um we only check initially when you build a mikah you have to check it for leaks to make sure there has aaka that doesn't have any leaks because the beginning has no once you've established that there's no leaks so then you only have to check it if there is a reason to believe that maybe you come back and you see the water is not there's usually a line around the mikah to like a different color tile You' fill it to that line if once you come you see that it's um an inch beneath it so then if you have a reason to suspect there a leap you have to check it okay what is the R's opinion of a floating PL the cover are there any shers when you remove the cover um what is the purpose of the cover oh the floating P I know what mean the purpose of the cover of a floating passive cover is to keep the humidity out of the building and to keep the heat in the mikah there's absolutely no problem with it um even if some water gets on top of it and when you take it out it goes back into the m there's absolutely no problem as long as you have 40 saw hopefully you'll have 40 saw in there besides the water on top of the cover okay let's go to another uh another set of pictures here this this coloring here is a little bit off because of the florescent lighting but it's really uh just the inside of the building so this is a similar idea that and this is where the water goes down into into the B this is where this is a um this not a t this is a pipe straight pipe and they made a hole in the pipe and they put this into the hole um with a hope that the water is going to run down this way um which I think the wish I think it did but this is not so easy this was not cut straight it was cut with a it was cut to fit this hole which they made in this pipe and um they probably SED it with cocon compound or something to make it fit which is 100% Co this is a k yes okay so this is the inside of the k m there's two Buras not that you need two burs it's just a practical thing that you can clean out this side and then when you fill it up above this hole so which the board on the other side it'll be a c you can you can clean this mikah and do backwards and forwards you can do that as many times as you want as long as you have one mikah that's intact while you clear out the other as a matter of fact the in press was that way that there was steps going down on this side and steps going on that side when they wanted to um clean this makeer took out the water and then they filled it up again with regular water until the hole and then they went and they clean out the other side and that's it was okay so this is water is coming in it goes through the water goes through a hole over here this is the hole from the goes through a hole into the bar the same thing okay this is okay this is outside the building and this water this instead of using a t joint they just uh drill the hole in in the pipe in this pipe which is going into the building and they just drill the hole and the W came splashed over here and then because the angle of of this pipe it went down into the okay now this over here is a metal grain pipe that came off the gutter and went in over here beneath this part this is over here there's a there's a question over here because the water maybe could collect on this place where it's um IND so this pipe went beneath it and um they this pipe they made a hole in this pipe and this pipe went all the way down over here and here they put a cookon compound this is because over here actually if you turn it around you turn this pipe around and now it can't uh this was sealed but it doesn't matter they attached it first to the building they sealed it so that's that's question okay so this is the all right so over here you can see that for over here they took off the cap at the end of this Gutter and the water went down into this metal pipe and went down over here and this is what we saw before how it was attached over here went down over here and then it went the so you can see it better there's there's actually a hole in this gutter where the water goes down over here but the cap taken off over here in order that it should not be considered a k because this is going in a downwards Direction so the water should flow down into this pinee and it may be able to hold water over here the end so that's why the C is taken off so this this is the same idea but if you take if you look carefully you can see that the distance from the top of the roof until the gutter over here is slightly less than the distance over here to the top of the gutter because it's going on a downward it's going downward slightly in order that the water that comes off this roof is if that roof should go down into this point do the same same okay let's take a few questions that we've been getting um does r have any Aces how to control splashing from the filter on the way back on the way back in I lose a tremendous amount of water because of it does understand is that clear um yes I don't know the way to control the splash splashing from the filter is that when the water before it go into the let's say a foot maybe before if you can widen the pipe um then it will not Splash so much but I think that maybe you're losing the water because the ham is supposed to be um por porous and you're losing the water because going into the ground uh maybe it's too porous and if you make a little bit less porous it would be you wouldn't lose all that water okay we did get another question in about the temperature of the water um it's my understanding that rabman holds that the temperature of the Mika must be 94 to 95 degrees and must never exceed 98 first is that an accurate representation of Rim's position second if so what is M for that is my understanding that m is water should not be yat which is much higher than 94 95 okay um there is in says when it is not considered water anymore and then not considered a to begin with but there's Tak that you should not go into hot water and when I made this mikah in Sun place and I worked out a system that the water could not get to more than 98 Degrees which is which is called and was brought down to check it out he was very happy with this system that I put up that it could not get to more than because there's some she say this pule if it is harder than that so it's very difficult to rely on ther on thermostats and thermometers exactly to the degree between 93 and 94 is a very comfortable temperature for most people and that's what I insist on okay okay this goes back to something we discussed before if you have all the aspects that you have and would there be any from either non kabad or kabad who would have a pbook I can't guarantee that no one's going to have a pi book well I say is that if you have all the aspects covered Accord to it's going to be C okay is it better for the pipe to be terracotta as opposed to P PVC really they used to use terracotta pipe terracotta pipe is like concrete um and that was fine um the meic today is to use plastic pipe basically because it's cheaper and and better um is more it is um more waterproof but um it is not um but the pl pipe is fine you could use it now if you need if you're using for the this pipe then terra cotta is the only one you can use you cannot use plastic pipe because it has to be Roy laer it has to be able to absorb and a okay we have one more set of uh one more set of pictures here okay does recognize this this one yeah it looks familiar um so over here in this setup it looks like was not a professional person that made this because the um concrete looks like was poured between this uh board and this looks like the the Earth so it was pour between the Earth and put anything on the side it doesn't matter you can do that it's that would not affect them it would not affect the okay um this is just um what they did over here was that these boards it seems that there was a floor before and these boards were put on the floor to hang this um to to hang this these boards on it they shouldn't touch the ground in order that the cement could go the concrete could go under the ground so it wasn't necessary to it wasn't necessary to hang it um but it probably would have been important to make sure it doesn't rise and um doesn't get pushed off I guess they didn't put it in yet okay so this is the this is the rebound which is put in and um it goes over here between this is where they P the concrete evidently this wall this wall hadn't been put up yet because um because there would have be one wall here and another wall over there okay so this is how the water came into the mikah the water came down from the roof now over here there is a metal gutter but what happened was they put a pipe plastic a plastic pipe on top of this metal gutter the P pipe was only a half pipe no was fo lengthwise so one end of the pipe was put under the asphalt shingles and this pipe was was resting on this metal metal gutter which was underneath it now this is the pipe drain pipe that goes to the to the ground for the from the metal pipe but the W didn't go into the metal pipe the water went into this half plastic pipe over here they cut a hole into the side of the PIP they just put put it on same thing over here so the water went it went this way went down this pipe and if went this way it went down this pipe um probably did the same thing over here and then this pipe over here goes into the basement of the house where they had the where they was about a m there's a question on the previous picture um if they are using rebar why aren't they using the green one or maybe it is green um no it wasn't green there's no that rebound has to be green it could be black just as good but why is he asking about green is there something special that green better rebar he says it's a better rebar what he says okay so these evidently maybe when this was built they didn't have the green one yet okay okay so this is a continuation of the picture before it went like this into the basement of a building this is the pipe that brought the rain water in and it probably went into a h next picture I don't know if that's oh yeah here yeah so here this is where the pipe ends it ends over here went into and this probably goes into okay so this is the same what goes over here and eventually goes into on the other side this wall the pump that pumps out the water from the Mika pumps it up like this if it's going to just clean the filter of water it goes over here through this filter and then it goes out like this the water goes into the and goes back into the MK if they want to if they want to empty the Mika so then this valve will be shut off this one be this which is off we put on on so the water will be forced up over here and it forced up here it probably went into a drain okay you want to go back to the picture before this one yes okay now there's another thing over here that this water over here this is a city water and when they want to um add when they want to um clean the mik they can just that City water goes through the samaka and it will go into the bar and from there go into the me so they want to add water they want to add water want change the water they don't change the bir water the the water in the B stays there but the water in the Bas side to if they wanted to change it they could do it that way so there must be some way of directing the water on the other side of the water there must be the must go somehow into a bar okay okay so this over here is the end of that ham it goes through the wall and it comes out over here it goes down in this white pipe over here now this looks like it's a barab bar because you see this hole over here in this ple PL glass which has um divided the top half of the from the bottom half of the bar and then it goes through this hole into the base f no it's not mik it has one bar under the other but the mik is that the is in the place where they they Mar been on that they Mar on that okay now this is interesting thing that nothing to do with M but has to do with how you keep the mik warm see the these are are um radiant heat pipes these are pipes which you put when when you put them on the ground like this hot water runs through them they cover with concrete and when all these PS cover with concrete but when you put on the heat it goes through it heats up the floor of the mikah and the floor of the mikah Heats up the water on top of the mikah so this is a uh very um it's a good way to heat up a mik because the heat in the mik is even because heat rises as opposed if you have a heating element on the side of the mikah very often the Bottom's going to be cold the middle of it is going to be uh lukewarm and the Top's going to be boiling on if there's a problem with this how does one fix it you pour the cement over here so you pour the cement over here now these boards I assume are there just to uh keep the um to keep the pipes in place until after the cement is poured they will take them out okay let's go over some some questions there does the r have any aor yeah to suggest to engineer to the engineers finding that the soil is Sandy and somewhat somewhat watery which suggests the need for very strong foundational Shoring to ensure Integrity of the building because of the depth of the dig this is very expensive is there any ASA um typically what what you do is you put in a couple of feet of stone into the into the on top of the Sandy Earth and um since the weight is dispersed over the whole B the whole M it's going to be full of water it weighs many tons and it won't it's not going to move okay um there was another question here is Terra Cotta absorbent enough for the amaka have it okay but they should do like the r said before mixing the sand into the cement correct okay okay we're at the end of the uh our pictures if there are any last minute questions uh you can chat them to the uh to the RO he says he did not understand the R's a on the Shoring so you only need uring where the weight is put on a certain place like if you have a scaffold so there are pillars and if all the weight is concentrated in one place and there's no weight on the sides of it they're going to go down into the ground but if you have a mikah which has a a floor which is all the way distributed over the whole area of the mikah uh maybe the whole mikah after after many years might sink in a little bit that's going to happen any place if it SS in a little bit so then you'll have to uh it's it's not the mik is not going to leak because so because the Earth is Sandy generally not a problem since all the weight is distribute over such over maybe 8 10 feet by 15 ft or whatever theis is it should not be a problem okay um we'll try to take some last minute questions um the the inter I'm not sure I'm not sure I read that right the interf of the building Integrity of the building is that question okay it sounds like it's it's a detailed question maybe he should call the r directly to discuss how what they could do the person who asking people asking they asking about the building they're not asking about the M that's what they're asking okay so it's like this there's two ways how to build a building the expensive way is that you first put up the walls you need a foundation for the walls and then you put the floor inside the walls that's the expensive way to do it and that's the way that's usually done but the better way how to do it is to first pour the floor the whole floor and and you make a little bit thicker than normal usually it's uh three 3 or 4 in the floor you'll make it 6 in and then you build a building on top of the floor building then nothing's going to go anywhere it's it's not going to uh sink in because the whole floor takes the way to the building and that way you shouldn't have any problems I'm not a builder but I'm just saying that that's seem me the easy
