I have a 3 yr old toilet that begins to sweat after about 20 minutes. I know it is not the wax ring because I replace them regularly and this one has never been used. It seems to do ok for a couple of months then starts sweating again. The only advice that I can think of is to flush less frequently or change out the wax ring but even though they are nearly new, it doesn’t seem like something you would want to try with someone’s life in your hands? Any suggestions on how to fix this problem without replacing the entire toilet?
