Need to repair a leaking toilet? The problem could be your outlet valve washers.

A cistern outlet washer, also known as a seating washer or toilet washer, is a gasket located at the base of the flush valve inside the toilet tank. Its purpose is to provide a watertight seal around the flush valve so as to control water release from the tank into the toilet bowl. It is therefore crucial to maintain a tight seat washer seal. If the seal is compromised, the cistern will not shut off properly after flushing.
