I removed a shower in the basement and found a hole dug around the shower drain.water was filling the hole,filled hole with concrete,water still seeps in but the drain pipe seems to be clogged.I covered pipe before pouring concrete.Could this be groundwater or a backed up pipe somewhere.I plan to waterproof that part of basement.I do not understand why the shower drain pipe is clogged
