This has been leaking for a while, and has slowly gotten worse. The picture is of the shower drain. The shower is on the 2nd floor, so the picture is in-between the 1st and 2nd floors and its tight in there!! You can see that someone before me has applied some sticky black goop that pulled right off. What is the best way to fix this without pulling out the entire shower? It looks to be bent a little, and it looks to maybe have threads??? Not sure. Thanks for the help! My wife hates using the downstairs shower! I'm just not sure what products are out there to repair stuff like this.
