We had a tub plug stuck in the toliet. We took the toliet off, re-moved the plug :-) went to put the toliet back on with the new wax ring, when tightening the bolts the bolt broke though the flange. Went to the local hareware store, one guys said replace the pipes. Took off the downstairs ceiling, the pipes are a lot of angles. went back to hardware store. next guy said all you need is a super ring. bought it. when to put it over the old flange. It seems the space is quite large between the super ring and floor, like 1/2". and it also seems that the dog ears on the super ring might stick out to much and hit the toliet
