Found the P trap under the sink was leaking, knew I smelled something wet under there. You think I could just get a generic replacement? No.
Got a replacement ABS elbow, had to glue in a threaded piece to match the pipe to the sink, put it in and the threads are a different size now than in 87. I need to cut the original off the wall stub, put in a slip collar and a piece of pipe to match the new elbow and make sure it lines up with the sink.
I can't find the old one anymore, I tossed it across the room when I found out nothing matches, I think I sent it into another dimension. I've looked everywhere.
