## Overview

The Geberit Flush Valve Rubber Washer is a precision-engineered metal seal designed to replace worn-out washers in Geberit flush valves. Measuring just over 2.5 inches, it prevents water leakage by restoring a tight seal, ensuring efficient flushing and reducing water waste. This genuine part is easy to install and built to last, making it an essential upgrade for maintaining optimal toilet performance.

## Description

Geberit flush valve won't seal properly and is constantly passing water into the toilet pan but there is no sign of an inlet valve failure, it could very well be that the base sealing washer need to be changed. Overtime as the flush valve is opened and closed, small imperfections tend to occur in the surface of the rubber washer causing the washer to be warped and not providing an adequate seal.
