    Hidden slab leaks are not simple repairs. You first have to determine where the leak is. Water will follow the path of least resistance so the actual leak may not be under where you see moisture. The floor will have to be jack hammered up and the leak uncovered. The leak repaired and the slab patched. I'd suggest calling in outside help but if you want to try it we will help. What's your pleasure? Regards, Tom

    You say you can see where the water is draining from, my first question is: is this a Hot or cold water pipe leak or is it a leak for one of your drain pipes. My second question is: how can you see where it is draining from and if you can see it how hard would it be to reach, How far is it to the leak from where you are looking from.

    Answer these questions and maybe we can help.

    Hmmm I have the same problem. I have it narrowed down to a rough area of the slab and a likely drain line. Sounds like Jack hammer to me... Sigh.

    We use Slab Locator to locate slab leaks. It locates leaking pipe within about 16"...

    However, if you call an experienced plumber, he can isolate the leaking branch, cap it off and reroute new line through the ceiling. This option is not always possible but in many cases is.

    That would work if the branch were feeding a single fixture . However
    The problem with that is that by capping off the branch is that it may also be supplying other fixtures and you would be dropping down and opening up walls to tie back into the manifolds. In my area one 1/2" branch can supply three fixtures.
