OK, tell me whatever you can about them. I need to replace the wax ring in the toilet located in the master bedroom. I've never done one before. To tell you the truth, I'm scared to death of it. I don't know what I'm gonna find when I lift that toilet up off the floor. Every time the main sewer line clogs up, the water backs up and comes out around the base of the toilet. If the sewer line is clear, the toilet will flush without leaking. I know I got a bad sewer line, but I want to get that one toilet squared away before I replace the sewer line.
