5. Operation
The GROHE 37349000 flush valve provides a reliable flushing mechanism with adjustable volume control.
Flushing the WC:
To flush the WC, simply press the flush button or lever on the valve. The valve is designed to deliver a consistent flush based on the set volume.
Adjusting Flushing Volume:
The flushing volume can be adjusted between 6 and 9 liters to conserve water. Consult the technical diagram or the internal mechanism for the specific adjustment screw or lever. Typically, a small adjustment screw allows you to fine-tune the amount of water released per flush. Turn clockwise to decrease volume, counter-clockwise to increase.
6. Maintenance
Regular maintenance will ensure the optimal performance and appearance of your GROHE flush valve.
Cleaning the Surface:
- Clean the GROHE StarLight chrome surface with a soft cloth and mild soap or a non-abrasive cleaner specifically designed for chrome finishes.
- Rinse thoroughly with clean water and dry with a soft cloth to prevent water spots.
- Avoid using abrasive sponges, scouring pads, or cleaners containing alcohol, ammonia, or harsh acids, as these can damage the chrome finish.
Internal Maintenance:
- Periodically check for any signs of leaks or reduced flushing performance.
- If flushing performance degrades, the internal components (e.g., diaphragm, seals) may need inspection or replacement. Consult a qualified plumber for internal repairs.
7. Troubleshooting
If you encounter issues with your GROHE flush valve, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Weak or incomplete flush | Low water pressure; partially closed stop valve; clogged inlet filter; incorrect flush volume setting. | Check main water supply pressure. Ensure stop valve is fully open. Clean or replace inlet filter. Adjust flush volume setting. |
| Continuous water flow after flush | Faulty diaphragm or seal; debris in valve mechanism. | Turn off water supply. Inspect and clean the diaphragm/seal for debris. Replace if damaged. |
| Leakage from connections | Loose connections; damaged seals or washers. | Turn off water supply. Tighten connections. Replace any worn or damaged seals/washers. |
| Loud noise during flush | High water pressure; loose internal components. | Adjust flow pressure to within recommended range (1.2-5.0 bar). Inspect internal components for looseness. |
If the problem persists after attempting these solutions, please contact GROHE customer support or a qualified plumber.
