My toilet starting leaking into the kitchen below. When I popped the toilet, I first thought the problem was due to the fact that the slots in the closet flange itself were broken (and indeed the previous homeowner must have known this since he apparently tried to glue it and secure the toilet with a heavey dose of silicon caulk).
However, on closer inspection, I noticed that the 90 degree sweep below the closet flange had a crack maybe 1/8" wide going about halfway around the circumference.
Now replacing the closet flange and sweep below is not easy since I would have to either rip up the bathroom tile floor or the kitchen ceiling below to gain access.
Any suggestions on how to repair this in place? - Could I reliably seal the crack with plumber's 2-part epoxy putty or some other glue/caulk?
Regarding the broken slots in the closet flange itself, I purchased a stainless steel ring that supposedly goes over the slots and screws through the same holes that attach the closet flange to the floor. - Assuming that the closet flange is currently screwed into a wooden subfloor, what type of screws are recommended for securing the closet flange repair ring so as to get as strong and lasting a bite as possible?
