Thread: sub-concrete floor pipe leak ?

Hybrid View

  1. #1

    Default sub-concrete floor pipe leak ?

    I have a basement bathroom.. I was putting in some new flooring, and the old vinyl was really moldy on the bottom when I took it out. after drying the bare concrete floor, i noticed there was still a damp spot. I did some wet testing by pouring water into the sink drain and the shower drain, and it the damp spot appears after I do this. The plumbing is below the concrete floor, so I suspect there is a break in the abs pipe that is allowing water to come back up through the floor ?
    The pipe on the right is the sink drain, and it goes through the far wall and into/through the concrete floor at the middle of the wall (as shown).

    dunno.. Will post a pic.. Can anyone tell me how the toilet, sink and shower plumbing will look below the floor ? I guess I'm going to have to break open the concrete floor to have a look, but I want to minimize any additional damage.



    Any other ideas / approach ?

    From what You've said,and asked, I don't think You're qualified, to handle this one. Best advice is to call a plumber

    You can rent an elec. jackhammer and bust up the floor. plumbing waste and drains will be directly below the concrete, Then run water again to find leak and repair. test plugs for toilet and shower and other fixtures down stream will give You a better shot at seeing the leak. At least You'll save some $$on the bust up ,if You bring in a plumber. Report back after demmo

    A partner saw (concrete saw) will help in getting a clean break and not tearing up more than you have to.

    Default leak

    Have you ever heard that water runs downhill? If so, and if the drainline is not obstructed, how is water from a leak in a drain pipe under the floor going to flow uphill, through a concrete floor, and show up as a wet spot?
