4. Setup and Installation
Follow these steps to replace the lower supply assembly in your EcoFlush toilet.
- Prepare the Toilet:
- Turn off the water supply valve located at the wall behind or near the toilet.
- Flush the toilet to empty the tank. Hold the flush handle down to ensure as much water as possible drains out.
- Use a sponge or towel to remove any remaining water from the tank.
- Disconnect Old Assembly:
- Disconnect the water supply line from the bottom of the existing lower supply assembly. Have a small bucket or towel ready to catch any residual water.
- Inside the toilet tank, locate the large nut that secures the lower supply assembly to the tank. Unscrew this nut.
- Carefully remove the old lower supply assembly from the toilet tank.
- Install New Assembly:
- Insert the new EcoFlush B8100-01 Lower Supply Assembly into the hole at the bottom of the toilet tank, ensuring the rubber washer is correctly seated on the outside of the tank.
- From underneath the tank, thread the large plastic nut onto the shank of the new assembly. Hand-tighten the nut securely. Avoid overtightening.
- Reconnect the water supply line to the threaded connection at the bottom of the new assembly. Hand-tighten, then use a wrench for a final quarter-turn, ensuring a snug fit without overtightening.
- Check Connections:
- Ensure all connections are secure.
- Slowly turn the water supply valve back on.
- Allow the tank to fill. Inspect all connections for leaks. If leaks are present, gently tighten the connections further until the leak stops.

5. Operating Instructions
Once installed, the EcoFlush B8100-01 Lower Supply Assembly operates automatically to refill the toilet tank after each flush. No manual adjustments are typically required for its basic operation.
- Water Level: The assembly is designed to fill the tank to the appropriate water level. If the water level is consistently too high or too low, refer to the Troubleshooting section.
- Flushing: The toilet will flush normally once the tank is filled.
6. Maintenance
Regular maintenance helps ensure the longevity and efficient operation of your EcoFlush B8100-01 Lower Supply Assembly.
- Periodic Inspection: Periodically check for any signs of leaks around the connections or within the toilet tank.
- Cleaning: If mineral deposits accumulate, they can affect the valve's performance. Turn off the water supply, drain the tank, and gently clean the visible components of the assembly with a soft brush and mild cleaner. Avoid harsh chemicals.
- Float Mechanism: Ensure the float mechanism (if applicable to your specific toilet model's fill valve) moves freely without obstruction.
7. Troubleshooting
Refer to the following table for common issues and their potential solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Toilet tank does not fill or fills slowly. | Water supply valve is closed or partially closed. Debris in the fill valve. | Ensure the water supply valve is fully open. Turn off water, remove assembly, and check for debris. |
| Continuous running water. | Water level too high, causing overflow. Flapper not sealing correctly. | Check the water level adjustment (if applicable to your fill valve type). Inspect the flapper for proper seal. |
