Okay, heres the story. I have a stand up plastic shower in the downstairs bathroom. I noticed that a puddle of water was forming from it into the basement cement floor which is right on the other side of the wall. There is a gap of the wall at the bottom in the basement area where you can see the bottom of the shower. My first guess was that it needed to be recocked. I did that and put the rubber strip tape on it as well to ensure no water would leak out. It still is, and now I assume that the leak must be the shower drain pipe. Not sure where though. I looked down it with a flashlight but saw no cracks. Basically I would like to know what to do next? I am getting some minor mold on the wood in the basement where the leak is occuring, so I def. need to solve this problem very soon. Thanks
