2. Setup and Installation
Proper installation is crucial for the correct function of the Geberit Double Flow Bell. If you are unsure about any steps, it is recommended to consult a qualified plumber.
2.1 Safety Precautions
- Always turn off the water supply to the toilet before beginning any work.
- Flush the toilet to empty the tank.
- Wear appropriate personal protective equipment, such as gloves and eye protection.
2.2 Installation Steps (General Guide)
- Remove Old Mechanism: Disconnect the water supply line from the fill valve. Remove the old flush valve by unscrewing the large nut from underneath the toilet tank. Carefully lift out the old mechanism.
- Clean Tank Base: Thoroughly clean the opening at the bottom of the toilet tank to ensure a good seal for the new flush valve.
- Install New Flush Valve: Place the new Geberit Double Flow Bell into the tank opening from the inside. Ensure the rubber gasket is correctly seated on the outside of the tank opening.
- Secure with Nut: From underneath the tank, thread and tighten the large plastic nut onto the flush valve. Hand-tighten first, then use a wrench for a quarter to half turn more. Do not overtighten, as this can crack the tank.
- Connect Water Supply: Reconnect the water supply line to the fill valve.
- Adjust Water Level: Turn on the water supply and allow the tank to fill. Adjust the fill valve to ensure the water level is appropriate, typically about 1 inch below the top of the overflow pipe.
- Test Flush: Perform several test flushes to check for leaks and proper operation of both flush volumes.

3. Operating Instructions
The Geberit Complete Double Flow Bell features a dual-flush mechanism designed to conserve water. The operation typically involves two distinct flush options:
- Small Flush (Partial Flush): Pressing the smaller button or partially depressing the main button (depending on your toilet's flush plate/handle) activates a reduced water volume flush. This is ideal for liquid waste, saving water.
- Full Flush (Complete Flush): Pressing the larger button or fully depressing the main button activates the full water volume flush. This is intended for solid waste, ensuring thorough clearing of the bowl.
Familiarize yourself with your toilet's flush plate or handle to understand how to activate each flush option.
4. Maintenance
Regular maintenance helps prolong the life of your Geberit Double Flow Bell and ensures efficient operation.
- Cleaning: Periodically inspect the flush valve for mineral buildup or debris. If necessary, turn off the water supply, drain the tank, and gently clean the components with a soft brush and mild, non-abrasive cleaner. Avoid harsh chemicals that can damage rubber seals.
- Seal Inspection: Check the rubber seals (especially the flapper or sealing washer at the base of the bell) for wear, cracks, or deterioration. Worn seals are a common cause of leaks and should be replaced promptly.
- Adjustment Check: Ensure that the flush buttons or lever operate smoothly and return to their original position after each flush. Verify that the water level in the tank is consistent and at the correct height.
5. Troubleshooting
Here are some common issues and their potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Water constantly runs into the bowl. | Worn or dirty flush valve seal; improper seating of the bell. | Clean or replace the flush valve seal. Ensure the bell mechanism is seated correctly. |
| Weak or incomplete flush. | Low water level in tank; obstruction in the flush valve; faulty flush button/lever. | Adjust the fill valve to raise the water level. Check for debris in the flush valve. Inspect flush button/lever for proper function. |
| Toilet does not flush. | Disconnected flush button/lever; severe obstruction. | Reconnect the flush button/lever to the flush valve. Check for and remove any obstructions. |
| Leak at the base of the tank. | Loose mounting nut; damaged tank-to-bowl gasket; cracked tank. | Tighten the mounting nut (do not overtighten). Inspect and replace the tank-to-bowl gasket if necessary. If the tank is cracked, it may need replacement. |
If these troubleshooting steps do not resolve the issue, it is advisable to contact a professional plumber or Geberit customer support.
