Original Geberit Spare Parts for WC Cisterns

In this section, you'll find a complete assortment of original Geberit spare parts for maintaining concealed cisterns (Sigma, Delta, Omega, and Twinline series) and exposed cisterns. Using only original spare parts guarantees perfect water tightness, quiet refilling, and the longevity of your plumbing system.

The most requested spare parts for maintenance:

• Float valve (filler valve): Responsible for filling the tank with water. If it whistles or doesn't close, it should be replaced.
• Bell (Drain Battery): The central mechanism that raises the water.
• Bottom Seal: The rubber seal at the base of the bowl. If it's dry, water will drain into the toilet.

Is your Geberit leaking? Here's what to buy.

Problem: You see a constant trickle of water in the toilet or hear the cistern constantly filling.

Solution (Quick Diagnosis):

1. If water comes out of the overflow pipe (at the top), the culprit is the float , which is not closing properly or is full of limescale. Replace it with the Geberit Unifill (Universal) model.
2. If water is leaking from below, the problem is the bottom gasket of the central bell. Often, simply replacing that rubber gasket (which costs a few euros) is enough to solve the problem.

How to find your mailbox code?

Don't buy randomly! Geberit has produced dozens of models over the past 30 years.
To be 100% sure:
1. Remove the control plate.
2. Look behind the plate or on the clear/white plastic cover inside.
3. You will find a numeric code (e.g. 109.300.00.5 or 110.xxx... ).
Use that code to search for the compatible spare part on our website.
