Why Replace the Flush Valve Seal?

The flush valve seal is the critical component that holds water in the tank between flushes. When it wears out, water continuously seeps into the bowl — silently wasting water and driving up utility costs. The Kohler 1131496 is a quick, affordable fix that restores a tight seal and keeps your dual flush system performing exactly as intended.
