Pride Plumbing was called out for a water leak behind an AquaSource toilet. Our inspection found that the toilet tank's tank-to-bowl gasket was leaking. We turned the water off to the toilet; drained and removed the tank; used a Lavelle 481BP Korky tank-to-bowl gasket kit and replaced the gasket, bolts, and rubber washers; reset the tank; and tightened the bolts. We also replaced the tank's water fill valve with a new Fluidmaster PRO45B model and tested for leaks with no further issues. We provided a cost estimate to replace the toilet with a new Gerber Viper model. This would include inspecting/cleaning/replacing the flange, replacing the toilet bowl, toilet tank, flapper, water fill valve, tank to bowl gasket and bolts, seat, wax ring gasket, toilet bowl bolts, toilet bowl bolt washers, toilet bowl bolt caps, and above-floor stainless steel braided water supply line.
