- Water Flow Control: Use the two side handles to control the water flow. Typically, one handle controls hot water and the other controls cold water.
- Temperature Adjustment: Mix hot and cold water by adjusting both handles simultaneously to achieve the desired water temperature.
- On/Off: Turn the handles clockwise to shut off the water flow and counter-clockwise to open it.
- Aerated Spray: The faucet provides a soft, aerated water stream for comfortable use and reduced splashing.
6. Maintenance
To maintain the pristine appearance and functionality of your Dornbracht faucet, follow these maintenance guidelines:
- Regular Cleaning: Clean the faucet regularly with a soft cloth and a mild, non-abrasive cleaning agent. Avoid using harsh chemicals, abrasive sponges, or cleaners containing alcohol, ammonia, or bleach, as these can damage the platinum finish.
- Drying: After cleaning, always dry the faucet with a soft cloth to prevent water spots and mineral buildup.
- Aerator Maintenance: If water flow becomes weak or uneven, the aerator may be clogged. Unscrew the aerator from the spout, clean it of any debris or mineral deposits, and then reattach it.
- Avoid Scratches: Do not use sharp objects or tools directly on the faucet surface.
7. Troubleshooting
If you encounter issues with your faucet, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Low water flow | Clogged aerator; partially closed stopcock; debris in water lines. | Clean or replace aerator; ensure stopcocks are fully open; flush water lines. |
| Leaking from spout | Worn cartridge; loose connections. | Tighten connections; replace cartridge (professional service recommended). |
| Leaking from base | Loose mounting nuts; damaged O-rings. | Tighten mounting nuts; replace O-rings. |
| Water temperature inconsistent | Issues with water heater; unbalanced water pressure. | Check water heater settings; consult a plumber for pressure issues. |
