Basement Plumbing & Radon Rough-In [Cabin Project]

The Utility Room and Plumbing System

As we take a closer look at this area, it becomes clear that it's going to be our utility room. The floor drain is located here, and as you can see, it's a new rural inlet area with a backflow. This is another one of those same valves we've installed earlier, but it's a 3-inch valve because it's part of a line coming off the main line. Just like before, this valve has its own always-shut backflow, which means that water will always be flowing in from under the floor drain and into the main system.

We've also fed a condensate line drain right here, which is designed to handle moisture from our HVAC system (Heat, Ventilation, and Air Conditioning). This system works in a couple of ways. First, it allows us to drain condensate moisture directly into this area. Second, it helps to prevent the P-trap under the floor drain from drying out, which can sometimes lead to sewer gas coming back up. The condensate will drip into the P-trap and keep it moist, reducing the likelihood of sewer gas smells in our basement or other areas.

Looking at this pipe right here, we have a 2-inch stand pipe that eventually leads to our kitchen sink on the main floor. You can see how it drains down and disappears into the main system, which then flows out to the septic tank. Further back, we have our toilet in the basement, which is simply straightforward: you flush the toilet, and sewage flows into this 3-inch pipe that takes water from the upstairs showers and vanities. However, this 3-inch line also has its own backflow valve, just like before. Although it might seem redundant, following the rules of the plumbing code means we have to install an additional valve here.

Moving up to the main floor, our 4-inch main pipe comes out of the ground and turns into a 3-inch stack in the wall. This 3-inch line will eventually lead to our main floor toilet, which will dump into it. You can see that this pipe has a clean-out on its back side, allowing us to access the main drain if we need to snake or clear any blockages.

If you look at this overhead shot of our plumbing system, you'll see the radon detector located here, as well as all the pipes in the floor. The pipe under the footing leads to a septic tank, which will be connected to our plumbing system soon.

The Inspector's Feedback

We had to address one issue with the inspector's feedback on this system. There was an error in the 2-inch valve installation that we had to correct before proceeding. Thankfully, it was discovered early enough to make the necessary changes before the floor was installed.

"WEBVTTKind: captionsLanguage: enhi it's Shannon here I'm back from host improvements.com and in today's video we're visiting the cabin build and we're going to have a look at all the Ruffin plumbing in the basement floor before the floor gets poured and also the Ruff in for uh radon mitigation uh which is code here in my area so we've got to put some radon uh some pipe in the the floor under the radon Rock just in case we have an issue down the road so right here this black pipe that you see this uh 4in block ABS could be PVC uh this is for our rate on uh mitigation if we ever need it so in our area it's required to be put in in new homes uh whether you need it or not uh so that it's there in the future if the need arises so uh basically it needs to just extend out to the middle of the of the basement area there's no cap on the end or anything and if uh raon gas becomes a problem uh it can be uh sucked out with a fan a proper fan and ducked it outside so this pipe gets buried under the under the floor we use this rock this radon Rock just kind of 1 in to half inch sort of rock and uh that allows any gas that's in there it can move around below the slab uh so this will get completely covered in the Rock then before they pour the floor they're going to lay some poly sheeting and seal it up and seal it to to the walls put the rebar in and pour the floor uh but anyways we we've got this in here so in future if we ever need it so what I did is I put the 4 in in it's pretty basic there's no real grading needed or anything it just needs to be underneath this rock and then I brought it up vertically here in the corner you can see I've got a cap glued on the end here but if we ever need it we can cut this cap off extend the pipe uh install our fan and it would go out and and uh be vented right outside so I put it in this corner just because our utility room was too full of stuff and you'll see in a minute there's a lot of Plumbing other actual Plumbing pipes in the floor and it was just too busy to do all this so I brought it up over here we're we're going to have the electrical panel in this corner of this bedroom anyways so I'll be building an enclosure around that this will just get enclosed simply inside of there as well now the next thing we've got is all our plumbing rough in so in this in this general area well in this area is the uh basement bathroom and pretty much directly above it is going to be the uh main floor bathroom so you can see here what we've got over here is uh this actually has to get changed cuz it's going to be a wet vent so that needs to be changed to 2 in this pipe that comes down here and it slips along the back and comes over here and ties in uh right there anyways plumbers coming back out to change that to 2 in but you get the basic idea so this this vent this pipe here is going to work as a wet vent for the vanity sinks so if you can imagine it's going to go up into the uh main floor get above flood plane which is you know above your vanity counter and it'll tie back into the main vent which is what this one will be in the wall beside it and then the two vanity sinks will drain into that it will then uh flow around and it dumps in right here which is the same place that the basement shower is going to tie in and then into the 3-in drain okay so our main vent our main vent is this one so it'll be 3 in going all the way up through the first story and through the roof and through the attic but it comes down here and it converts into 4 in once it gets below the floor so it'll follow around out here then it goes out and what you see right here is back flow preventer so this is a an always closed that's how it's classified backflow preventor which basically means there's a little flapper in there I don't want to take this apart cuz he's got a pressure tested again so I'd rather leave it uh the way it is but there's basically a flapper in there and it it always sits closed until fluid which is always supposed to flow this way will come and open it up and it'll allow it to go out and under the foundation and out to our septic tank which is out going to be outside this this setup on here is just so that when I back fill the Rock and they pour the concrete uh they can pull that up to the level it needs to be and it keeps the concrete back so that we will always have access I can get this open down through this hole okay we ever have to get out that so uh so anyway so yeah our main main goes out and to the septic okay now other things that are tying into this is this is a floor drain it's going to be a floor drain in the utility room this whole this whole area here is going to be utility room I know it's hard to visualize right now but uh so floor drain it also this is a new rural inar area it also has a back flow so this is another one of those same valves it's just that it's a 3in cuz it's in a in a line coming off the main line so that's same thing in there so it has its own always shut uh back flow which in this case the flow here is always going to be there's a P trap down below here it's always going to be out this way right cuz it's dumping into the main and leaving so the back flows in here like this um now we've we've fed a condensate line drain right here this will be for the hvr so it'll uh drip any condensate moisture it has into here and it actually works uh in a couple ways so it comes through the floor drain and through the floor drain's trap and because it's not a big amount of water uh we can drain it into there and it what it does is it actually keeps that P trap uh from drying out cuz a lot of times on a for drain you'll get some sewer gas coming back cuz your uh your PE trap under the floor drain dries out right cuz it's not too often they get need to be used or get water in them okay so the condensate will drip in there and kind of keep that better chance of keeping that floor drain P trap uh always sealed up if you ever notice Su gas smell in your in your basement or whatever and you've got a floor drain go dump uh a gallon of water down that and it'll likely uh dissipate and go away and just fill your P trap back up again now this pipe right here this stand pipe is a 2in stand pipe that eventually our kitchen sink from up on the main floor will drain into and you can see it will drain down that pipe off and into the main and and gone to the septic as we move a little further back here this is our uh our toilet in the basement so it basically uh pretty self-explanatory uh you flush the toilet sewage will run in the 3-in pipe here all the way out it this 3-in picks up the shower and the upstairs vanities um but it it flows out and into the main and then out to the tank and again we had to put another back flow this isn't always closed again we had to do another one on this uh on this 3in line so it seems a little uh redundant but I guess uh you got to follow the rules right so so that's the main uh main gist now up on the main floor so this is this was our 3-in or sorry our 4in main down here in the ground and it turns into a 3-in stack in the wall that's going to go right out of the right out of the cabin and up at the main floor our uh main floor toilet will will dump into that so okay so you can see it's got a clean out on this back side right there so that'll allow us to go you know if we ever have to snake the main drain or anything that'll allow that to be done outside I'll just show you where the main drain comes out under the footing and eventually we'll get hooked to the tank so I'm standing on the basement wall right now here's all our plumbing here's a good overhead shot of all that there's the radon here's all our plumbing in the floor here and then it goes out as you can see right here and goes under the footing heading to the tank so over on this side that's where it comes out you can see it there it's got an orange test cap on the end down there right there and when they put our tank in which will be right here they will uh connect the tank to that I think that gives you the basics on what's what's required uh like I said there's a couple couple things there he's got to come back and change that one 2 in the inspector caught that so uh good thing he did because it's a lot harder to change after the floor's in so there's our basic Plumbing we're going to have
