    Default Basement shower drain to toilet?? Some advice please before I JACKHAMMER!

    Hi there,
    I'm currently in the process of demolishing my basement apartment and am going to be putting in a shower where there once was a tub. In order to move the drain to the center and resize it to 2", I'll have to jackhammer up the slab. It looks like the existing 1 1/2" drain is pointing in the direction of the toilet, but the kitchen is also that way. My question is this; is it possible to have the shower drain connected below the toilet flange? I'm really hoping that I don't have to go all the way in to the kitchen where the sink drain is. That'd be a lot more floor to rip up.

    Question #2;
    I'm also going to be putting in a new toilet flange regardless as the one that's there is all messed up. I currently have 3"copper but am thinking that cutting it and switching to ABS will be easier than soldering the big pipe for an amateur. What type of non-solder connection can be used below grade and have concrete poured over it?
    Thanks in advance!
    Chris

    Answer #1
    You can connect anywhere downstream of the toilet flange as long as the toilet flange is vented in some manner

    Answer #2
    You can use any Mechanical type connection. MJ or fernco couplings. Both are non solder connections. Fernco are more forgiving

    Default drain

    You have to break the floor until you reach a spot where you can connect a 2" drain. And Fernco rubber couplings are not approved inside the building in most areas.

    I'll check the code requirements in my area (Toronto, Ontario). Not going to be inspected but it's good to go by the book regardless. It'll be below the slab, though. DOes that count as outside?

    Beleive me, I'm very close to Toronto and you will be fine with what I mentioned. As a matter of fact , I worked in toronto for 20 years before I moved.

    In that case, any suggestion for a good plumbing supply in the West end? HD doesn't seem to have too much in the way of 3" fittings. I've got 3" copper for the toilet right now.

    Judging by your description of the project, you won't be needing anything special. Being below the slab, you will probably cut on the horizontal peice, which most likely is 4" pipe (double check what size your pipes are before cutting anything)

    Depending how west you live.


    Nuroc plumbing supply on Rexdale Blvd between Kipling and Martingrove . I forget the number of the building.

    Desco plumbing supply at 35 Wingold ave.
    The head office for Desco at 65 Worchester Rd

    Penmar Plumbing supply, Dundas St. 1/2 block east of Runnymede Rd.

    If these at too far west, tell me what old municipaility you live in and I'll accomodate you with the closet supplier.


    BTW, I'm still in the GTA, just a little further West outside of T.O.

    Nuroc is your best bet. They have everything and anything to do with plumbing. They rarely say that "it's out of stock"

    I'll be picking up my kerdi shower base tomorrow, figuring out the final layout and with any luck, jackhammering in the afternoon. I'd appreciate it if you folks could keep an eye out for a post in the evening if I do get it done; I'll post some pics of the existing drain setup; with any luck it'll be a simple fix, but with my luck it probably won't!
