Installation Instructions
Tools Required:
- Adjustable wrench or spanner
- Screwdriver (if needed for cistern cover)
- Bucket and sponge (for residual water)
Step-by-Step Installation:
- Turn off Water Supply: Locate the water shut-off valve for the toilet, usually on the wall or floor behind the toilet, and turn it clockwise until the water flow stops. Flush the toilet to empty the cistern.
- Remove Cistern Lid: Carefully lift the cistern lid and set it aside in a safe place.
- Disconnect Old Valve: Disconnect any flush buttons or levers attached to the old flush valve. Depending on the model, you may need to twist or unclip the old valve from its base. Remove the old valve from the cistern.
- Clean Cistern Base: Clean any debris or sediment from the base of the cistern where the flush valve sits. Ensure the surface is smooth for a proper seal.
- Install New Valve: Place the new Geberit 240.622.00.1 Dual Flush Valve into the cistern, ensuring it is correctly seated on the sealing gasket at the bottom outlet. Twist or secure it according to the specific design of your cistern's base.
- Connect Flush Mechanism: Reconnect the flush buttons or levers to the new dual flush valve. Ensure the full flush and half flush mechanisms are correctly aligned and functional.
- Restore Water Supply: Slowly turn the water shut-off valve counter-clockwise to restore water supply to the cistern. Allow the cistern to fill.
- Check for Leaks: Inspect all connections and the base of the flush valve for any signs of leaks. If leaks are present, turn off the water supply and re-tighten connections or re-seat the valve.
- Test Flush: Perform several full and half flushes to ensure the valve operates correctly and the cistern refills properly.
- Replace Cistern Lid: Once satisfied with the installation and operation, carefully replace the cistern lid.
Operating Instructions
The Geberit 240.622.00.1 Dual Flush Valve offers two flushing options to conserve water:
- Full Flush: Press and hold the larger button or lever for a complete flush, emptying the entire cistern.
- Half Flush: Press and release the smaller button or lever for a reduced flush, using less water for liquid waste.
Ensure the flush button/lever returns to its original position after each flush to allow the cistern to refill completely.
Maintenance
Regular maintenance helps ensure the optimal performance and longevity of your dual flush valve.
- Cleaning: Periodically clean the inside of the cistern and the flush valve components to prevent mineral buildup and debris accumulation. Use a non-abrasive cleaner and a soft brush.
- Seal Inspection: Annually inspect the rubber seals and gaskets for wear or damage. Worn seals can lead to leaks and inefficient flushing. Replace any damaged seals promptly.
- Float Adjustment: If the water level in the cistern is incorrect, the float mechanism on the fill valve (not part of this flush valve) may need adjustment. Refer to your fill valve's manual for instructions.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Toilet runs continuously or refills slowly. | Flush valve seal is worn or obstructed. | Turn off water, remove valve, clean seal, or replace the seal if damaged. |
| Weak or incomplete flush. | Water level too low; flush mechanism misaligned. | Check fill valve for proper water level adjustment. Ensure flush buttons/levers are correctly connected to the valve. |
| Flush button/lever sticks. | Mechanism is dirty or misaligned. | Clean the flush button/lever assembly. Ensure it moves freely and is not obstructed by the cistern lid. |
| Water leaks from the base of the cistern. | Flush valve not seated correctly; damaged gasket. | Turn off water, remove and re-seat the flush valve, ensuring the gasket is properly aligned. Replace the gasket if damaged. |
