How to install Basement Bathroom Plumbing A to Z (Part 1)

you [Music] okay here we are here on one of my clients jobs down in right outside of Hershey Pennsylvania the sweetest place on earth we're working right outside of it and we just started the first phase of a what I call a free quarter a bathroom and three quarts bathroom is a bathroom that has a toilet a sink and a shower a full bath will be a toilet sink in the tub shower and a half bath obviously would just be a sink and a toilet but we're going to have a 4-foot shower over here in this Bay that you see here all right we got exactly 48 inches from this wall over to this wall and right down in that corner down in there it's going to be a 4-foot shower and over here we're going to have the sewage ejector which is one of the most important ingredients in a basement bathroom the sewage ejector is what goes down inside the concrete floor and all the pipes from the bathroom from the toilet the vanity from the sink they all run under the concrete into this thing called a sewage ejector which we're looking at right here this is the actual sewage ejector pit this whole pit goes down inside the floor all right this will be flush with the concrete when we're done so we're jackhammering a hole in the corner here and what we did was we took the lid to the tip and we used it as a template we drew a circle around that with our pencil we went right right around the edge with our pencil and now we're jacking that circle out I'll start the digging process because we're going to dig a hole deep enough and wide enough to put that entire soon as you check your pit in there and that's an item that we purchased at Home Depot you can also get them at Lowe's at the big box home centers so the first thing we're going to do is get our sewage ejector in the floor and then I'm going to show you how we're going to be jacking the floor from the toilet location which is right over here on the floor and I'm going to show you you know how to determine how far off the wall and what size hole to Jack to lay your your pipe in in the floor for your toilet that's going to run right the floor right into the sewage ejector we're also going to be putting it a shower I'm going to show you how to figure out where your shower drain is going to go in this 4-foot shower so that you can Jack the floor from the shower drain back over to the sewage ejector pit and our last thing we'll be doing is our sink which is going to go right in this corner here I'm going to show you how to run the pipe from the sink and how that's going to drop down into the concrete floor as well and make its way over to the sewage ejector plate so we're going to get this pit jack first here and then we'll give you a little lesson on how to lay out your toilet your shower and your sink so that you can finish the jackhammering in the floor all right so these guys are going to dig out the pit now this is going to take these two boys probably about two hours to dig this hole maybe three hours this is the most labor-intensive part of the job but this is where you can save yourself a lot of money by doing this yourself but the sewage ejector in is it's really all labor if you can manage to figure out how to dig a hole you can put your sewage ejector pit down in the floor so I'm gonna say anybody can do this it just depends on how ambitious you're feeling because it is it's time-consuming and it's very laborious to dig these holes so we're gonna get this dug once this is completely dug can we get the pit that pit right over there all the way down in the floor it's about three feet deep like I said we're going to come back we're going to show you how to layout the shower putting a four foot shower and how to layout the shower drain how to layout the toilet and layout the sink and then I'm going to show you how we're going to Jack the floor open to connect all those pipes now underneath the concrete floor and run them into the sewage ejector okay they're working their way down in there are about a half of the way down now and they're using a spade shovel and they're just chipping away out of here see how much dirt so far is come out of that hole and they're only about half way down they're gonna keep digging until they have it deep enough to drop that entire pit down flush to the floor okay so what we're going to try to accomplish here today with the the beginnings of this bathroom project in the basement here is connecting all of our schedule 40 PVC underneath the floor now schedule 40 PVC is what you see here it's this white pipe here and again this is an item that we've bought at Home Depot this is two inch schedule 40 PVC we're also going to be using four inch schedule 40 we're going to be using three inch and we're going to be using an inch and a half and all the lines that run underneath this concrete floor are going to be inside the schedule 40 PVC now what's going to be down underneath the concrete floor is mostly going to be two inch and three inch PVC all right and I'm going to show you how we're going to connect all that later on in this video but for now the first thing that you're going to do is begin with your ejector pit wherever you're going to put it and we've actually put the ejector inside the bathroom all right so it's in a closet in the bathroom now this video isn't on how to design your basement if you want to design your basement learn how to lay it out we do have a video it's just called designing and it's at the basement store at basement finishing videos comm you can buy a video that will help you design your basement including the bathroom layout which will show you the different possibilities for locating the sewage ejector but we've got it in a closet right inside the bathroom you can see right above the hole that we're digging there is some of that schedule 40 PVC I was talking about it and you may not have schedule 40 PVC in your home you may have black cast iron if it's a newer home chances are no matter where you are it's going to be some type of schedule 40 PVC coming in through the through the basement to them to the main sewage out of the house whether it's public or private sewage you're going to have some of this 3-inch pee but you got to connect your sewage ejector plumbing which is going to come out of the top of the sewage ejector into this plumbing that you see strapped to the wall up here because right here that's where the sewage goes out of the house all right that that goes right through the wall and out to the street you probably have something like that in your basement all right that pipe right there where it goes through the wall is about 40 inches higher than the floor all right and since water doesn't run uphill the only way we're going to get the sewage out of this floor down the sewage ejector pit is to pump it up and connect into these pipes that are up here so that's what we're going to be doing later in the video we're going to be connecting the plumbing from the sewage ejector that we're going to put on the floor to this sewage pipe that you see here strapped to the wall inside the closet [Music] all right that's one of the that's one of the parts of the project that you're going to see us complete in this video the other one's going to be connecting the toilet all right that's going to go it's going to flush right down into the concrete floor so we're gonna have to jack up in the floor and connect it from point A hit the toilet to point B the sewage ejector and that's all going to be done underneath the floor so we're going to show you how to lay out that section of the floor that you're gonna have to jackhammer out as well as the shower which is going to sit right over here the showers gonna drain down into the concrete floor I'm going to show you how to tie that in as well and lastly we'll have the sink which sits over here that's also going to drop down into the floor and connect underneath the concrete floor so phase one is let's get this sewage ejector in the floor and then we're going to work backwards from the sewage ejector to the to the shower of the toilet and the sink this is our electric jackhammer that we rented at a local rental center it plugged right into a regular 110 outlet and we rent this guy on every job he's commonly referred to as Jackie Chan when our jobs this is Jackie Chan and Jackie comes with us to all the fruit ejector pit jobs and I mean it's just like having almost as good as having an air jackhammer maybe not quite as powerful but does a real good job comes on the dolly you rent it rolled in your door thing and returned to the same thing so we'd only just get it for a one-day rental and that costs us about $55 to rent that for a day so that's an electric Bosch jacking [Music] total choice alright now we're gonna test this fit out and see if it's fitting down in the hole properly see how much deeper we gotta go oh yeah we got a white and you can see we got bad about 16 inches yet we got about two feet of it down in there right now instead of keep chiseling that a little bit wider and digging in a little deeper [Music] well using the jackhammer to loosen up the dirt and stone down in the hole so you can use that to bust the concrete as well as to loosen up the soil down there so it's easier to dig when these guys love to run Jackie Chan we got our sewage ejector pit in the floors you can see right here it's flush with the concrete right down flush with the floor that's how far down they go so that's down in the floor about three feet there the next thing we're gonna do now that we got the pit in there is we're gonna determine where we're going to be jacking the floor for our toilet a shower and our sink all right so I don't know what model shower you're gonna be getting we always put in a fiberglass 3 piece or 4 piece remodelers shower which you can buy at Home Depot and we're using a four footer here if this particular one is 36 inches deep by 48 inches wide and for now just for jacking purposes what we're going to do is we're going to find the center of the 4-foot which is 2 foot make a mark and we're going to come back across half a 3-foot which is 18 inches one and a half feet and we're going to make it we're going to make this crosshair there and we're going to take a nice big section of the floor out around those crosshairs there you see the plumber just drew a nice 1x1 box there alright that box is going to get jacked out you want six inches each way on the on the new Center marks [Music] now he's drawn some lines coming across where he's going to be connected into the toilet line now the toilet is going to be going right there where Tom's got his circle there now the center of the toilet is always 12 and a half inches off the back wall that's standard 12 and a half inches is where the center of the toilet flange is gonna be okay and then wherever you want it left to right in the bathroom we just centered ours between the show outside wall in the shower okay and then what he's doing is he's making about a 10 inch trench going from that toilet flange right there straight across and right into the sewage ejector pin you can see we're going to be passing right under this little wall here with that trench now that's as close as you got to get for jackhammering okay now the pipes are gonna be a lot more accurate than our concrete trench is gonna be but for now we found the center of the shower I made a nice 1x1 box we marked out where our flange was going to be for our toilet and we're going to show you how all this goes together later in this video but for now we just want to get the floor opened up so we can get our PVC in there our schedule 40 PVC so what we're doing is we're going on an angle and the reason we're going on an angle is because sorry sewage ejector is over there in the corner okay the pipe is going to be going right in that hole that you see right there in the side of the subject er pit and that's down inside the floor so what we're gonna do is we're going to go exactly from that hole in the side of the pit straight across the bathroom in a straight line right over to the toilet flange alright that's what we did for the toilet now the shower what we did is we came right up right off of our shower box that we drew down there alright one by one box on the center part and we just came straight across in to the line that's going to be coming across from the toilet all right we came in perpendicular alright so the shower drain is coming in on the 90 degree angle to the shower to the to the toilet line it's going to become a all right that that makes it as easy as you can make it for fittings later on we put all these drain pipes together in the floor now the sink what we're going to be doing is we're going to be coming up 28 inches 20 inches we're gonna go over on it and we're gonna come across through the 2x4 wall so this is going inside the wall and then we're going to drop down into the floor and then we'll drop down inside the floor and we'll come across on an angle just like we did on the shower and we'll tie into the toilet line you all right we're always going to be tying into the toilet line because the toilet line is always a straight shot from the toilet flange straight to the sewage ejector so the sink and the shower are normally tying into the main line coming from the toilet and the toilet line is generally going to be a 3-inch piece of PVC we're not going to get into all that size of the pipes right now how we connect them under the floor yet we're still in the phase of how do we get the plumbing underneath the floor to connect to the sewage ejector all right so that's the game plan for this bathroom and I'm going to send the guys back in here in a minute and exactly where we drew these lines on the floor the sink coming over our toilet coming across to the sewage ejector and our shower line coming 90 degree right down into our toilet line as well we're going to Jack all that out once we get that jacked out I'll turn the camera back on and I'll show you what that looks like finished your bathroom configuration will not be exactly like this and really guys I've been doing this Fuhrman almost 20 years and no two bathrooms are ever laid out exactly the same but the principle is the same no matter where your toilet and shower or your tub shower and your sink are located you're going to be connecting underneath the floor under the concrete floor to the sewage ejector pit so we've got our little friends Jackie Chan back out here notice our guys got ear protection on and he's got his eye protection on because chunks of concrete will fly up when you run these things so make sure you wear your ear and eye protection we're gonna let him get started on that and we'll be back here with you in about let's say a half hour guys ready oh yeah we're ready let's do it so we are working our way from the toilet right underneath the wall of the ejector you can see there we're going right under this with a wing wall that's old you shower right down to the toilet all right and then we can't from the shower we Jack out that one by one hole and we came straight across perpendicular to the toilet drain okay and that's the way it's going to tie in underneath the floor there all right see we're going like right underneath that wall right back down to the toilet flange and right across to where the shower drains gonna be all right so the last one that they have to Jack here yeah it's gonna be this one coming for the sink which is gonna come right across and tie right into this one that's coming from the toilet so that's next all right okay we got it all jacked out now let's still run over that one more time here and we got our sewage ejector down in the floor we're coming underneath the wall beside the tub and going straight over to the toilet flange okay the center of the toilet flange is remember I told you 12 and a half inches off the back wall to the center of the flange and then you can send to the toilet left to right wherever you want it we centered ours between the wall and the edge of the shower pan okay so our toilets dead center between the shower and the wall and twelve and a half inches off the back wall we jacked our sink drain from the sink plumbing wall straight across into the toilet drain line pan over there into the shower area we jacked out that one by one hole there for the shower drain and we came straight across also into the toilet drain line and then everything just funnels down right at you side of the sewage ejector all right so now all of our concrete's busted out the bathroom is now ready for the plumber to start the under the floor PVC schedule 40 PVC so the next thing we're going to do is probably start on our shot on our toilet drain and we're going to plumb that right in underneath the wall over into the pit and then I'm going to show you how to set your shower pan your fiberglass shower pan over there in that corner and we're going to show you how to trap that and run that into the toilet line and finally the last thing I'm going to show you how to do is how to plumb your drain line for your sail all right the phase one of the bathroom is not complete which is if you're using a sewage ejector jack in the concrete and getting the floor prepped for all the underground plumbing all right so Tom the plumber is now laying out the fittings in the floor he's making sure that his toilet flange is twelve and a half inches off the wall I'll show you what he just did right there and what parts he has in his hands there he's got a there's actually two pieces to this here he's gonna take that apart show us what he's got there okay he's got a three-inch 90-degree elbow it's called a street 90 okay it's got a it's got a bigger flange on this side and not not so much of a flange on this side all right it's called a street 90 and he also has a 3-inch toilet flange all right that just goes right over top of that street 90 so you take the street 90 and you plug it right into the bottom of there at the bottom of the flange and I don't get glued in there and we'll show you how it was gonna be that another set and that's what you got all right the toilets gonna pull onto here the sewage is going to go down and around and into the floor and that's going to sit down in there like that I remember the center of this flange is twelve and a half inches off the plane of this wall to the center twelve and a half so he's got that turned down into his trench and it's pointing in the direction of the sewage ejector over there all right right now we'll just drive through everything nothing's getting glued together yet so that's in the rough proximity where it's going to end up I moved down the trench a little further we have a three inch to two inch T all right and again this is a home depot item he's gonna do in that trench right there it's gonna be the sink line coming down inch and a half or a two inch sink drain line then that's gonna run right down in to this fitting okay then this fitting is going to connect to the toilet flange 9 out of 13 here all right moving on down the trench a little further we've got another one of those 3-inch all right three inch from both sides to two inch on this end T's and that's heading up the hill it's a directional 2-inch T 3 2 2 and it's heading right up here into the hole in the floor where the shower drain is going to go into the concrete floor all right so the shower drain is going to be in here it's going to run down the trench and it's going to go right into here the shower drain is a two inch drain and it'll drain right into here and then I'll have a piece of 3-inch between this fitting and this fitting all right a small piece of three inch PVC we'll connect those two so we've gone from the toilet to the sink a sink drain will be coming down through there two inch and we've going from the stick drain down the shower drain which is coming over for the shower pan right there and then the last leg of that journey is going to be from here and right underneath this wall right down and in the side of the sewage ejector pit right into that three inch hole right there all right we're going to come out of the pit out of that three inch hole and the floor all the sewage is gonna dump into that hole into the pit onto the floor right over into this three to two fittings in the shower all right and basically in a simplistic way that's that's it well we got to do now is cut the proper lengths of three-inch pipe to connect the pieces and the 2-inch pipe to connect into our three to two tees and all the plumbing under the floor will be complete and that's what Tom's working on now now he's putting the rubber gasket on a special fitting it's a four to three fitting it's a reducer a43 reducer again that's a home depot product now these pits come with a rubber gasket Tom's got the rubber gasket right there and sand and what they do is that rubber gasket goes right into the hole in the side of the pit and forms a gasket Union between the plastic tub and the PVC from the three reducer it's going to shove that through the gasket you really got to push hard so once you get your gasket then you can put the gasket inside of the pit there you take your fitting on the inside out push it through the gasket with a little bit of soap suds on it a little bit of dish detergent and just push that into the gas tap it in with a hammer if you need to it's going to be really really snug and there you have now there's our four to three reducer now four is going through the pit and then it reduces to 3 inch and the reason it's reduced into three inches because we're going to be connecting to three inch up this end here now we're going to be going right into this three to two T that's coming down from the coming down from the shower drain all right so we're gonna be going from the pit three to two with the shower two-inch out of that right on up to the shower dream which is all 2-inch then we're going to travel up the trench little further pick up another three to two which is going to zip over to the plumbing wall over to the vanity and our sink tree that's going to come down and tie into that and then boom right into that 90 degrees street elbow three inch street level put into the toilet flange and that's everything underneath the or inside the bathroom the only thing that we're going to do in addition to that is when we come off a 3 inch up to the shower we're going to trap the shower I'm going to show you how we're going to put a 2 inch trap underneath the shower pan when we set that we're not going to be doing that till till tomorrow when I pick up the shower but I'm going to show you how to do this shower from A to Z all right as well as the sewage ejector you're gonna see how we completely plum that out the top of the lid later and make all the connections into the existing home plumbing all right let me tie into the home plumbing from the pit we're gonna show you how to do that and how we're going to run our sink through the plumbing wall and drop down into the floor and also how we're gonna vent the whole bathroom all right so the plumbers get ready to cut some 3-inch pieces and start is what we call dry fitting dry fitting is when you connect all of your pipes before you glue in to make sure everything fits once you have a completely dry fitting reassemble everything and then you'll reassemble everything gluing it and priming it as you go and I'll show you how we're going to do that in just a minute okay everybody put on your thinking caps here we're getting ready to start this underfloor plumbing here with our master plumber Tom who right now is starting the first leg of this PVC schedule 40 PVC underfloor two inch plumbing here coming from the shower Ryan as we said before he was going to be trapping this shower all right and showing what a trap his tom the trap that is a two inch trap all right again you can buy that at Home Depot there's two pieces alright there's two pieces go together just like that we're dry fitting everything that's what we're doing dry fitting is when you don't glue these out test everything make sure everything fits before your final the final gluing and Johnny I guess I guess we're cutting for ourselves yeah now we we called the manufacturer of the shower cuz we don't have it on site I should call the store that we're gonna buy it from him we found out the center of the drain in this particular shower is 16 and 3/8 inches roughing off the off the framing to the center by 24 I it's a 48 inch shower 24 inches is the center coming left to right and off the back wall we're going 16 and 3/8 so the first thing Tom's gonna do is he's gonna set this trap up down inside the concrete floor at those measurements 16 and 3 ace by 24 see he's coming 16 and 3/8 off the back wall what's the back wall there to the center of his two-inch trap and remember we're just getting things in what position right now we can we can adjust things and fine-tune things before he blew things up yeah so he's gonna throw a little bit of the loose stone we have here in the bathroom down there just to hold that in position temporarily so that he can build the rest of his pipes off that and here's where we're gonna pick it up he'll be our next perfect huh so we're coming off the back side of the trap you just saw us put that in there and we're gonna be going over into our Korean spike here we're gonna pick it up into a directional a two inch directional to three by three by two inch directional three by two instructional t Home Depot kind of mind you he's gonna aim that trap what you still loose it's my throat he's gonna aim that straight down towards the three-inch pipe in that two to three directional fitting it's gonna be tough for me to film but I'll do the very best I can here so you can see what Tom's doing you can see he's lining things up to go from point A the end of travel to point B he's going to cut that two to three directional T right into that three-inch pipe down there on the floor we're gonna and then you're gonna run a piece of two inch pipe between the two fittings he's measuring for that right now I'm gonna do a 14 inches 14 and a half because we can always recut it so he's gonna cut a piece of two inch PVC schedule 40 PVC between those two fittings then now he's marking the 3-inch right where he needs to cut into it so that he can put that three to two directional t on 14 and a half I said marking is two inch fourteen and a half now he's gonna take those two pieces of pipe over to our saw I'll show you how to cut these on a regular regular wood saw it's so much easier than trying to cut them by hand so we just used the carbide tip blade on our chop box the same box that we use to frame with and you'll want to wear safety glasses when you do this cuts right through that BBC like it's butter [Music] all right so there's our 14 inch piece for Horrors inside it make a pipe openings okay so after you cut it Tom said that you want to make sure that you clean off the PVC burrs that might be hanging on the inside of the pipe make sure your fittings are nice and clean before you put them together and glue it's kind of like putting together a puzzle he's gonna plug that 3-inch piece right into the side of the sewage ejector right into that four to three reducer you saw put in all right right into there I still were just still dry fit we're gonna put everything together under the floor before we glue it now I should point out that the pipe that's going into the pit right now this 3-inch pipe it's pitching downhill all right everything rolls downhill towards this sewage ejector pit all right but the pit will be the lowest point of all the plumbing when it's done so he's actually plumbing uphill right now towards the toilet and back over to the shower drain all right so now he's got the three to two director directional on the end of the three under the downhill and now he's plugging that 14 inch PC measured for between the shower trap and the three to two directional in the floor probably gonna get recalled a three now they make all types of fittings as you can buy to put this puzzle together no two puzzles are the same I'm telling you guys that mm that are watching this you will never do two bathrooms that will have an exact same plumbing layout it will never happen that's a standard 90 rims on both ends where it actually fits the pipe on both ends and this is a street 90 it fits the pipe on one end and the other end fits in a plate they call that a street 90 and I'm gonna use a street and I need to connect these two so he's using a street 90 break down into that three to two directional yeah and I'll recut this 14 inch piece now I just try another thought I'm gonna take another 3/4 of an inch off it's always nice when you do put your drops in it they come from the top that's that's as sweet as you can get when you do drop you know top drops okay so he's dropping down into his lateral pipe and that's the that's the big pipe that's going from the sewage ejector all the way up he'll down to the toilet flange right that's his main that's his main discharge line under the floor the big three inches the main line the sink and the shower are coming into the main line through 2-inch PVC so we're going to be connecting into that 3-inch pipe twice in two inch PVC setups one for the shower which we're working on now and then we have another trench over here we're going to be tying in the sink so we're gonna do it once for the shower and once for this set you cannot put a shower in without trapping it okay you have to trap your shower so that 2-inch trap that's down there it's two pieces they're not they're not glued together when you buy them but they will be together but they'll be loose but they won't be sticking in one another when you buy it at Home Depot whatever plumbing store you're going to buy it at so one end of the two-inch trap goes towards your downhill slope to your main lateral to your pit all right right around the other end of the two-inch trap gets a straight piece of pipe coming straight up out of it which you can see right there and that goes into the bottom of the shower pan or the tub if you're doing a tub so tom has put that fourteen and a half inch piece in there on the end of the trap right over to the the ninety degree drop and and it looks like he's got a nice connection they're gone now you got to make sure that that's 2-inch piece of pipe the 14 inch piece is pitched downhill everything has to run downhill lifting this but I still want to check my 16 and 3 A's cadets got a picture down the hill - and you gotta be and you're on your two foot more yeah check that alright so he's got to be 24 inches the one right and 16 and 3/8 inches the other way according to the manufacturer specs on that drain and so he's a 24 that way real Justin in a little bit more 24 or by 16 and 3/8 that's about me right there okay so right now essentially he's done plumbing the shower PVC drain line that's all it took he's just going from the shower trap to the three-inch main line and that's all it takes now that could have been a 20 inch piece of pipe there he put between the trap in the in three to two directional or it could have been a you know an 80 inch piece depending upon how your how your basements laid out how how you guys are going to be designing your onto the floor plumbing no two bathrooms are the same and there is a fitting for just about everything agent you can buy to make your puzzle work everybody's long it's gonna be a little different now we're gonna pick up this way all right so the next thing Tom's going to attempt to do is just gonna push the the toilet flange and that 90 degree and you can see you've got a 90 degree three inch fitting coming off the bottom of that toilet flange she's gonna be working that into the equation here yeah so he's got to go from the center of the toilet flange which we told you it's 12 and a half inches off the wall and then centered wherever you want your toilet to be in the bathroom but it's always 12 and a half inches off the wall for standard standard settings so he's going to get the center of the flange off the back wall behind the toilet at 12 and a half inches to the center sees lining that up now so he's got it in a rough position there now he's gonna measure between the toilet flange and the ninety degree that he put on the bottom of it over here the 3-inch all right came up with thirty three and a half so now he's gonna cut a piece of three inch PVC thirty-three and a half over on the saw and drive fit that in there and if that fits it's that all set up that over that will complete the under under the floor plumbing for the toilet all right so he's putting the one end into the three two two directional tee okay tap in there with this hammer a little bit make sure it's a good fit putting is ninety on the end that's going to come up to the bottom of the toilet flange [Music] and my tip is my check was well gonna happen checking his twelve-and-a-half one more time gotta come in alright he's a little bit too long he's gonna have to cut a little bit off that 3-inch pipe yeah to make that work so he's gonna adjust that he has to be when he's connected to that 3-inch pipe the center of that toilet flange has to be a twelve and a half inches for the toilet to be sitting in the bathroom correctly when the job's done so he's gonna cut about an inch off there so he just said that we're gonna we're gonna finish up this toilet flange and then we're gonna work our way back up that trench there that we made the floor day one when we were jacking the floor out and tie that in [Music] and tie in that sink drain the exact same way that we just tied in the shower drain into another three two two directional with a ninety degree street 90 okay so let's run over those fittings one more time here while Tom's cutting that we got we got a piece of straight two inch PVC coming up out of the center of the trap the two inch trap and that's going to be going right into the bottom of the shower drain and we'll show you how we're going to do that later in the video we got the two inch trap coming around we have our fourteen and a half inch piece of connecting schedule four to two inch PVC that's going into a ninety degree this is a ninety degree 2 inch street 90 which is dropping right down into a four to power three to two directional tee all right and from there we're running from the directional tee right down straight in to the four to three reducer which goes right through the rubber gasket into the sewage ejector pit now that sounds like a lot of maybe a lot of Greek to you there but it's really very simple the fittings are really easy to purchase into fine when you're when you're shopping for them and what we're doing it's not rocket science on anybody can do this the big thing is is making sure all your fittings come up through the floor in the proper locations twelve and a half for that floor the flange which we got you know make sure that your shower trap it's coming straight up into the center of your shower pan and you'll get those instructions and dimensions with your shower I'll tell you exactly how to lay it out and then the rest of it is water and waste products run downhill so everything has to be pitching downhill towards the pit all right downhill towards the main lateral and over to the pit everything is running downhill all your plumbing has to be heading downhill towards that sewage ejector so everything ends up in the right place when you turn on the water when you flush the toilet when you I'm going to take a shower when you run the sink all the water will run downhill and eventually end up in that sewage ejector pit so now time he's got this 90-degree coming up exactly where he wants to come up and this is your typical 3-inch toilet flange all right it's not it's not opened up yet we've got to punch that piece of plastic out there where you see that TKO sticker but this is what you buy it's got a metal ring on it and the metal ring actually spins around okay so you can line up when you want to bolt to the floor you can get the holes and the mounting pieces exactly where you need them and on the bottom you've got a three-inch female all right this fits over a three-inch piece of PVC now Tom just cut a small piece of PVC and he measured that before he cut it so that his flange then would come right up flush with the concrete stopping that in there I'm just going to push that down into that ninety degree three inch and and then this flange has to be flush with the concrete so he's probably gonna have to cut some off that it'll go in there an inch but I don't want to try number two I need to be just like that okay so the the 90 degree fitting is down in the floor about five inches down there okay so the toilet flange doesn't fit right over top of this 90 you have to put a small piece a small piece of 3-inch between this fitting the end of the 90 degree and the bottom of the toilet flange and you have to cut that piece exact so that when you set your pieces all together the metal ring on the toilet flange will sit flush on the concrete that's what you're trying to get the metal ring flush on the concrete so when you putting your pieces together that's what you're measuring for now again we're dry fitting everything [Music] nothing gets glued here until all of the underground plumbing is put together and pitched and and everything's in the proper position then we'll take everything back apart one piece at a time prime everything and glue everything so there's 3-inch piece now there goes his toilet flange on top of that 3-inch piece twelve and a half inches off the back wall perfect so now he's in position for the toilet now next what we're going to be doing is another one of those three to two directional tees and we're gonna cut that right in just like we did down here for the for the shower we're gonna do that again right or the for the sink drain that's going to be coming down so Tom's using another one of those 90 degrees Street elbows all right it's gonna measure back to order where he knows his Plumbing's gonna be dropping down into the trench and he's gonna cut another piece of 2-inch PVC all right so this little setup right here is going to be cut right into that 3-inch pipe down there he'll mark that and we'll cut it well we'll mount this right in there and then this 90-degree street elbow here two inch street elbow will sit just like that and then we'll measure from here up there the end of the trench where we'll have another fitting where the sink train is going to drop down into the floor no that's all right that's what we're setting up right now and another 90 degree elbow 2-inch elbow as you can see we actually cut our plate out a little bit our bottom treated plate of our wall and this drain is gonna be coming up right inside the wall all right right inside the bathroom wall and from there it'll head over to the sink so tom is figuring out right now what he needs to do to get from point A over there inside the wall coming up in two-inch let's figure out what he needs to do with fittings to get from there down here and this little setup we're going to have here this takes a little bit of work a little bit of patience and remember you stop putting together a puzzle a puzzle that you're creating out of schedule 40 PVC and you can make the puzzle whatever you want as long as everything is positioned correctly in the bathroom where you want your fixtures to be and everything's running downhill it doesn't matter how you do it all right like I said no two bathrooms are ever going to be the same no two plumbing jobs are ever going to be exactly the same all right so now he's putting a piece of two inch schedule 40 inside that 90 degree 2 inch elbow and what that's doing is it's bringing his drain up inside the wall now he's gonna drive fit a piece of 2-inch pipe into that setup and get as close as you can down here to whatever he's gonna need to finish fitting wise to make this line up down here [Music] I'm just trying to line these two right here up where I know that's going this way and that'll pick it up right there and that should be what you need right there looks pretty good looks pretty good all right so now he has to mark the three-inch again down there and this time he's gonna have to cut out a piece of 3-inch big enough so that he can fit that three to two directional in there so you're gonna be putting things together and taking things apart a couple different times and carrying pieces back over to the sole and cutting them but that's why we do not glue anything until the entire project is complete onto the floor everything's fit right we've got to keep taking things back apart back together and there's no manual for this all right there's just no manual you're gonna buy anywhere it's going to show you how to do this because no two plumbing jobs are exactly the same this is actually the most difficult part of all the plumbing projects that I'm going to show you how to do in these plumbing videos the schedule 40 PVC stage of the job it's going under a floor for a sewage ejector is by far the most difficult plumbing that you'll ever do you know let me try to do so you can you can manage to pull this off in your bathroom which I'm sure you'll be able to the rest of the job is gonna be a breeze all right so Tom's got that cut piece of 3-inch back in the hole he just plugged on the three two two directional cheek and now what he's gonna do is he's gonna figure out how he's gonna get his sink to pitch downhill enough that he can get enough fall into his foot it ain't going no lower got to make sure all your schedule 40 PVC is below the concrete we I mean we like to be at least three or four inches below sometimes you just can't get that low but as long as you've got at least a good two inches of concrete over your pipe here you're in good shape so when I make this 137 now changing that one all right so now he just measured from his elbow down there where it's coming up inside the wall to his three two two directional here with the the two inch 90 degrees street elbow drop down and he measured between that flange right there all right that's where his piece is going to go in all the way up to the bottom side of that 90 degree elbow right there all right and you gotta make sure when you measure you want to make sure you measure inside inside these fittings you don't want to measure to the very edge you want to measure you want to measure inside this much more and that's about three quarters of an inch so you can measure to the edge when you just want to add three quarters of an inch more to your measurement because the pipe is going inside the whole way back to this plane right here all right so can't just measure to the edge you got to measure inside on the last year now what we've done before we started this project we went out we purchased about 40 feet of 2-inch PVC we ordered I believe just for the bathroom ten feet of inch and a half PVC and it's always good to go ahead and grab yourself a 10-foot section of three inch schedule 40 PVC okay that's the main pipes that mean the main lines 42 inch 10 inch and a half and 10 of 3-inch have that on standby when you start the project that way you won't be running back to the store six times for pipe can always return it if you don't use it all right so you cut that piece and he's dry fitting it now and he's got to make sure he has pitch on this pipe from here down to here so the water runs downhill into the main three-inch packing that together and making sure that he's got pitch [Music] and is that downhill get a two foot level and see look it's gonna be very close okay so you can see we're making some good progress here we got the shower down I got the three inch into the main sewage pit right there that's all connected up coming up the line here we tee it into our shower right there into the three inch and now we're teeing into our I'm gonna check for a level he's got a two foot level on there and what he's doing is he's checking the bubble on the level and I'll um out of the bubbles right you are level that he's running downhill so I'm running downhill three quarters of an inch which is good anything downhill is good he's running downhill three quarters of an inch from point A only up here down to here so he's got plenty of fall all right plenty of fall and you have to make sure you use a level for this and as a rule of thumb you should have an eighth of an inch of fall per foot all right so in four feet or an eight feet you'll fall on it all right eight eighths and an inch and an eighth of an inch per foot all right so the next leg of the journey here we got the I got the schedule 40 underneath the floor for the sense we have to try it in here it's pitching downhill three quarters of an inch now what we got to do is we got to go through one two studs with our drain line now what you're gonna want to do next is find the center of your bathroom drain now this is a 30 inch vanity so Tom's measuring off the wall there's dirty fifteen would be seven fifteen is Center okay so what you wanna do is make the center mark at 15 inches if you have a 36 inch vanity will be eighteen or foot 24 whatever it is about 20 inches code now all right and then the drain will enter the wall okay for the sink a 20 inches to the center up off the floor that's code alright 20 inches up off the floor is where the drain will enter the behind your vanity and this could be inch and a half from here to there so Tom just told us that instead of doing two inch PVC now inside the wall we're permitted to use inch and 1/2 PVC so it's easier to drill through the two by fours and use inch and a half so that's what we're gonna be putting in for a drain look so he's got a piece together what he needs an inch and a half now to make this drain work so what he has here he's got a regular what they're called sweep 90s two inch sweep 90s he's got two of them together one of them's turnt coming out of the wall towards the vanity I can even go a little bit lower if I want I mean by adding a piece put us in between one once yup so I know when I drill across the wall I can actually there's my there's my twenty mark I could actually be down there a little lower so right in this area there's even a little space where I'm gonna drill but naturally I want it I want to drill that ever so slightly there's level I want to be going downhill so my next mark is gonna be right about here is where I'm gonna drill there and there to come in to this alright so he made his marks on his study and he marked him so that when he drills through those two studs his pipe will be pitched downhill all right that's just common sense use a little level and Mark it so that you're you're running down here with your pencil marks then drill it drill out those pencil marks and you'll have holes that are pitched downhill now they drill these holes to drill these holes he's going to be using a hole saw no there's all different types of holes souls you can buy but you're going to want to get yourself something that's bigger than an inch and a half pipe we normally like to use like a two inch hole saw I might need so that it's really easy to push the pipe through the wall okay so we drilled through the 2-inch bit alright so now we got our two inch holes drilled through there and those holes are pitching down from there to there run downhill a little bit so that when we get our pipe through there it'll be running downhill a little bit speed through this all right that's going there all right now Tom's got a two inch directional T 2 by 2 by 2 and the reason he's using that there is because he's gonna vent alright and here's something we haven't talked about yet he can't invent the bathroom sink Mikey it's code that you vent all of your fixtures in the bathroom alright so to bend something means to allow it to breathe to the outside of the home the outside of the building fresh air coming in keeps the water in the pipes moving [Music] keeps the drain water moving freely ok if you don't have a vent you'll get a water vacuum you get a vacuum in the pipe and the water will not drain and that means the toilets will bubble and the shower drains will bubble and you will smell sewage gas inside your house which isn't very nasty it's like when you put your finger on top of straw in Anna and I think so did enough straw stays full you take your finger off the straw the water runs right out that's Benny ok well that's it I never thought of it that way but that's exactly what if Allah finds that simplifies what we were talking about with the vacuum if you don't vent you will get the finger over the straw syndrome alright so he's basically opening up the scroll right now and the straw would be the drain pipe and what we're gonna do is the top of this here gonna have great it's gonna go up into the outside of the house and bending it now going in the side door there where his tape is he's measuring for the drain 20 she's gonna cut a 28 inch piece from point A which is right here right in through the tube eyes and right to the 15 inch mark which is the center of this 30 inch vanity and remember that drain is center of your vanity whatever your vanity is up 20 up 20 is close so we're over 15 up 20 and that's where Tom's gonna plum things to over 15 up 20 and we're still dry fitting everything yeah nothing is nothing has been glued yet the whole way around zall Drive fitted if this pipe if I can't get this in it back together keep it in the wall we're gonna see if we can put a 28 in there all right we're gonna try to get a one piece inch and a half drain line in through these holes without having to cut it it's gonna be tight but I think he's gonna get it beautiful beautiful all right drive fitting the pieces back together he's going into his 2ht whoops we put right there that's a 2-inch team inside the wall trap all right beside the wall event rather not drop the baby there yeah pitching uphill over to the center of the vanity and to get that at 20 inches he's gonna put a little two and a half inch piece of inch-and-a-half PVC in there to get that drain exactly 20 inches centered off the floor and there you have it yeah waters gonna run down the I'm using directionals yep so the water has to go towards the direction sweeping towards a directional once again it's dropping into a 90 into a directional everything's directional - what's up [Music] that's simple stuff I mean no two bathrooms
