Pride Plumbing was called out for a water leak at the base of a commercial wall-hung toilet. First, we removed the toilet's Sloan flush valve and pulled the wall-hung toilet from the wall. This is when we found that the toilet's wax ring gasket was deteriorated and causing the leak. We then cleaned the wax ring gasket off, installed a new neoprene flange gasket, and reset the wall-hung toilet. After the toilet was reinstalled, we rebuilt the Sloan flush valve. Finally, we tested for leaks and proper operation of the toilet with no further issues and caulked around the base of the toilet bowl.
