    I have water up against a retaining wall. The sprinklers have been ruled out (turned off for two weeks and still water). The meter is not running so it is probably not a pressure line. It seems to get extra seepage when you run the faucets in the house. The problem is the drain pipes are go through the slab. Do I have to rip up the floor/slab?


    Note that the water does not smell like sewer water so probably just coming from the sink or shower.

    I have water up against a retaining wall.
    Are we talking about an exterior wall and foundation ? I assume there's no basement. You say" It seems to get extra seepage when you run the faucets in the house".
    How about when you flush a toilet or cycle the washer?
    Please come back with more details.

    Water tends to move horizontally. I would not rule out water coming from soil at this point. That retaining wall could be helping the water "hold" there longer as well. Especially if it was built in such a way with certain soile, rocks and a membrane. Is that retaining wall brick/block or cement?

    I would try to find a way to drain that water at the retaining wall first.

    Each sink, bathtub etc has their own drain pipe at the start of their location. Then some may connect together at different points - then they all connect to one large sewer pipe. I am not sure what faucets you run when you say you notice extra seepage in this area. The would have to be close to this point, and there are other issues to consider with that as well. (slab on grade or basement, etc)

    Just because it is waste from supply water, doesn't mean you wouldn't have "that smell" either.

    Before you go busting up your slab, spend more time identifying the problem.
