• Quiet Operation: Designed for quiet filling of the cistern.

4. Operating and Maintenance

Once installed, the flush mechanism should operate smoothly, resolving issues such as leaks and continuous water flow. Regular maintenance involves checking for limescale buildup, especially in hard water areas, and ensuring seals remain intact.

The kit's components are designed to be durable, but periodic inspection is recommended to ensure optimal performance and prevent future issues. The integrated flow filter in the filling valve helps maintain water quality and prevent blockages.

5. Troubleshooting

This replacement kit is specifically designed to address common problems in Geberit concealed cisterns:

• Leaks and Continuous Water Flow: The primary function of this kit is to resolve these issues by replacing worn-out seals and faulty valves. Ensure all seals are correctly seated and components are tightened appropriately during installation.
• Incomplete Flush: Check the flush volume adjustments on the lift bell (for small and large buttons) to ensure they are set correctly for your toilet.
• Slow Filling or No Filling: Inspect the filling valve and its flow filter for any blockages. Ensure the water supply is open and the flexible hose is not kinked. Adjust the water fill height if necessary.

If problems persist after installation, re-verify all connections and adjustments. Consult the detailed assembly instructions for further troubleshooting steps.
