I have replaced 1 toilet and at least 4 toilet rings on my toilet. The last time I doubled up on the ring but it still leaks. No, there are no cracks on the toilet.
The toilet is installed on a concrete slab. The last time I was under there, I put a level on the flange in the floor. I found that the flange is not level and is lower on the right side. I'm at a loss. I'm about to try it again for the fifth time. Any suggestions before I do this again?
