## Overview

The Geberit 816.418.00.1 Flush Valve Base Sealing Washer is a high-quality, clear rubber replacement part designed to fit all Geberit flush valves with a precise 62mm diameter. It prevents leaks caused by worn or warped washers, installs easily without removing the flush mechanism, and is trusted by thousands for restoring silent, leak-free 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.

Review: Easy to install, no more leak - Worked perfectly. My in wall toilet cistern had been leaking water into the pan slowly for a week or so. I was able to change the original rubber seal for this one without removing the mechanism from the cistern, just turning it upside down in place. Much easier then taking all the components out like the youtube videos had instructed. Worked instantly, no more leaking water.
Review: Perfect fit - A tiny bit thinner than original one however fits perfect and quality feels like original one so no more leakage and weird sound from water cistern.

### ⭐⭐⭐⭐⭐ Easy to install, no more leak

### ⭐⭐⭐⭐⭐ Perfect fit
*by G***. on 30 January 2026*

A tiny bit thinner than original one however fits perfect and quality feels like original one so no more leakage and weird sound from water cistern.

### ⭐⭐⭐⭐ Exact fit for many types of Geberit Flush Valve - normally no tools required
*by A***Y on 26 January 2024*

After about 15 years, our cloakroom toilet cistern was leaking a little due to the flush washer having become swollen in places. It was easy to fix and apart from a screwdriver to turn off the water (at the service valve), no tools were needed. The main requirement is to check that the washer is the correct one. The steps are: (1) remove lid of cistern: some just lift off, I had to unscrew the button push (2) turn off water supply to cistern and flush to empty (3) remove flush mechanism: mine unclipped, some have to be turned anticlockwise (4) Pull seal to the side to remove - it is very soft (5) Replace with new seal and re-assemble parts, turn on water and test The old seal was blistered and as temporary fix, I pricked the many blisters - what looked like water came out - and made the seal flat again.
