Our toilet is leaking at the base. The flange (?) is sitting flush with the floor. The 1st plumber said the problem was the old wax seal had a plastic bell on it and it was not needed. He put on a plain wax ring. The next day it was leaking. The 2nd plumber (same company, different person) said it needed the bell, but when I mentioned the 1st guy said that was why it leaked it the first place he changed his mind. He said he was afraid to try and fit the bell inside the pipe and he went with a regular wax ring. His parting advice was it might not work but don't give myself a headache looking down watching for a leak. Oh, and he suggested going up through the ceiling of the floor below and redoing the pipes.
I'm going crazy. Can you help?
