Uneven cast iron toilet flange
I'm doing a basement bathroom reno and am just in the middle of the demo stage. My question is that once I removed the toled the inside of the flange is corroded and uneven. It was leaking a tiny bit but not a lot, should I replace the flange or just use a extra wide wax gasket to seal it. If tit was in a wood floor I would just replace it but since it's in concrete I'm looking for a easier way.I just don't want to be done the new floor and realize that it still leaks.
