2. Setup and Installation
Installation of the Geberit AP123 flush mechanism requires careful attention to detail to ensure proper function and prevent leaks. It is recommended that installation be performed by a qualified professional.
- Preparation: Ensure the water supply to the cistern is turned off and the cistern is empty. Remove the old flush mechanism if present.
- Placement: Position the new Geberit AP123 flush mechanism correctly within the cistern, ensuring it is seated firmly at the base.
- Securing: Secure the mechanism according to the specific design of your exposed cistern. This typically involves tightening a locking nut from underneath the cistern.
- Connecting Components: Attach any necessary levers or buttons to the flush mechanism as per your cistern's design.
- Water Supply: Slowly turn on the water supply and check for any leaks around the base of the mechanism and connections. Allow the cistern to fill.
- Function Test: Perform several test flushes to ensure the mechanism operates smoothly and the cistern refills correctly.

3. Operating Instructions
The Geberit AP123 flush mechanism operates by activating a lever or button connected to the mechanism. Pressing or pushing the actuator initiates the flush cycle, releasing water from the cistern into the toilet bowl. The mechanism is designed for a single flush volume.
- To Flush: Press or push the flush button/lever on your cistern firmly and release.
- Refill: The cistern will automatically begin to refill after the flush cycle is complete.
4. Maintenance
Regular maintenance helps ensure the longevity and efficient operation of your flush mechanism.
- Cleaning: Periodically clean the cistern interior and the mechanism components to prevent limescale buildup, which can affect performance. Use non-abrasive cleaners.
- Inspection: Routinely check for any signs of wear, such as cracks in plastic parts or corrosion on metal components.
- Seal Check: Inspect the rubber seals for deterioration. Worn seals can lead to continuous water leakage into the toilet bowl. Replace seals as needed.
5. Troubleshooting
Common issues and their potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Water continuously runs into the toilet bowl. | Worn or dirty flush seal; misaligned mechanism. | Clean or replace the flush seal. Ensure the mechanism is correctly seated. |
| Weak or incomplete flush. | Low water level in cistern; obstruction in mechanism. | Check the water fill level. Inspect the mechanism for debris and clear any obstructions. |
| Cistern does not fill after flushing. | Faulty fill valve (not part of flush mechanism); water supply off. | Check water supply. Inspect and potentially replace the fill valve. |
