Common Toilet Problems

Problem: Fill valve turns on and off by itself or runs continuously (valve may hiss), but water level in tank remains below top of flush valve overflow.
Solution: Fill valve is turning on or running due to a slow leak in the tank, most likely caused by a worn-out flapper. Replace flapper with one of Lavelle’s premium Korky toilet flappers for optimum performance.

Problem: Fill valve turns on and/or continuously runs, and water level rises above top of overflow tube, spilling into overflow tube.
Solution: Clean fill valve cap. Follow service steps to remove cap and rinse under water. If cap and rubber diaphragm show significant wear, replace with a new cap assembly p/n R528.

Problem: Toilet tank fills too slowly.
Solution: Confirm that water supply valve is completely open and there are no kinks in supply line. If flow does not improve, then clean strainer by following the fill valve service steps below. If problem persists, replace with fill valve unit, p/n 528.
