A couple days ago I noticed in the ceiling some dripping water after taking a shower. There was really no reason the pipe would have broken, so I pulled up the shower grate thinking it was maybe somewhere between the connection to the drain pipe. My theory was there probably was just a worn out gasket somewhere along the way.
I didn’t install this shower, I’m guessing this outer white piece ring seals with the lower PVC piece, and that is what creates the connection. A gasket must be underneath it which then seals the floor of the shower.
Is that correct? I also couldn’t tell if that black ring stuff was some sort of sealant breaking off.. Does anyone recognize this? How would I go about fixing something like this? threading it off and putting a new gasket underneath? I just need to be careful as I have no access behind without ripping up drywall.
