The leak is probably the gasket seal. You may have used a regular wax ring which is not designed for that purpose. You need a wax ring, for a "wall hung" toilet, which has a "felt" ring insert.Originally Posted by richv
Why would you replace the best toilet that was ever made? Besides being a bad idea, you would have a major remodel project, and wind up with an inferior toilet.
All parts for the toilet's inside are available at your local Briggs Plumbing Fixture dealer.
