How to use
To install the mechanism, first shut off the water supply to the cistern and flush the toilet to drain the tank. Unscrew the existing valve from the side of the cistern and remove it. 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, then reconnect the water supply and check for proper operation and potential leaks during the refill cycle.
What to consider before purchase
Verify that your existing cistern requires a side-entry connection
Confirm that the water supply pipe uses a 3/8 inch fitting
Ensure the internal dimensions of the cistern provide enough space for the valve assembly
Usage recommendations
Regularly inspect the valve seal for debris or mineral buildup to ensure the mechanism continues to operate smoothly and maintains a watertight seal over time.
