Key specifications
Connection size: 1/2 inch
Installation type: Side filling
Compatibility: Designed for Geberit cisterns
Operation: Quiet filling technology
How to use
To install the mechanism, first shut off the water supply to the cistern and flush the toilet to empty the tank. Remove the cistern lid and unscrew the existing filling valve from the side connection. Insert the new Geberit side filling mechanism, ensuring the seal is correctly positioned to prevent leaks. Tighten the connection securely by hand or with appropriate tools, taking care not to overtighten. Once installed, turn the water supply back on and check for any leaks while the cistern fills to the desired level.
What to consider before purchase
Verify the connection type of your current cistern (side vs. bottom entry)
Check the compatibility with your specific Geberit cistern model
Ensure the 1/2 inch connection size matches your existing water supply line
Usage recommendations
Regularly inspect the cistern interior for any debris or mineral buildup that could affect the valve performance. If the water pressure in your building is exceptionally high, consider installing a pressure-reducing valve to prolong the life of the filling mechanism.
