A Geberit fill valve, also known as an inlet valve or float valve, controls the flow of water into the toilet cistern. It automatically stops the water supply when the cistern reaches the correct water level.

A constantly filling cistern may be caused by a worn fill valve, damaged seal or diaphragm, debris inside the valve or incorrect water-level adjustment. Cleaning, adjusting or replacing the valve may resolve the problem.

Check that the water supply is switched on and that the inlet connection is not blocked. A restricted filter, faulty fill valve or damaged internal component can also prevent the cistern from filling correctly.

Many Geberit inlet valves have a built-in water-level adjustment mechanism. Adjust the valve according to the specific cistern instructions and ensure the water level is set below the overflow level.

First, turn off the water supply to the cistern and flush the toilet to reduce the water level. Remove the valve or access the appropriate filter and clean away any dirt or debris. Reassemble the valve, turn the water supply back on and check for correct operation.

To replace a Geberit fill valve, isolate the water supply, empty the cistern and disconnect the water inlet. Remove the existing valve, fit the compatible replacement and reconnect the water supply. Check the connections for leaks and adjust the water level if required.

A hissing or running noise can indicate that the fill valve is not shutting off correctly. Dirt, a worn seal, incorrect adjustment or a damaged valve can cause continuous water flow.

Some issues can be resolved by cleaning the valve, filter or internal components. If the valve is worn or damaged, replacing it with a compatible Geberit fill valve may be the most reliable solution.

Check the Geberit cistern model, existing inlet valve, connection type, dimensions and manufacturer part number where available. Compare these details with the replacement product specifications before ordering.

Many Geberit fill valves are designed for straightforward maintenance and replacement, although access varies between cistern types. Always isolate the water supply before starting work. If you are unsure, professional installation is recommended.

Start by checking the fill valve, water level and inlet filter. Clean away any debris and check the valve adjustment. If the cistern continues to run after cleaning and adjustment, the fill valve or another cistern component may need replacing.
