Pride Plumbing was called out for a water leak behind a ProFlo toilet. We found the toilet tank's tank-to-bowl gasket was leaking. We turned the water off to the toilet; drained and removed the tank; replaced the gasket, washers, and bolts, the Douglas valve, the water fill valve, and the braided stainless steel water supply line; reset the tank; and tightened the bolts. We tested the toilet for leaks and the issue was corrected.
