5. Maintenance
Proper maintenance will ensure the longevity and optimal performance of your KUZOR faucet.
Cleaning:
- Clean the faucet regularly with a soft, damp cloth and mild soap.

Aerator Maintenance:
- If water flow becomes restricted, the aerator may be clogged with mineral deposits.
- The aerator is detachable. Gently unscrew it from the spout.

- Reattach the aerator securely.
Drain Maintenance:

- The drain stopper can be easily removed for cleaning.
6. Troubleshooting
If you encounter issues with your KUZOR faucet, refer to the following common troubleshooting steps:
| Problem | Possible Cause | Solution |
|---|---|---|
| Low Water Flow | Clogged aerator; partially closed water supply valves. | Clean the aerator (see Maintenance section). Ensure hot and cold water supply valves under the sink are fully open. |
| Leaks from Faucet Base | Loose mounting nut; improper sealing. | Tighten the mounting nut underneath the sink. Ensure rubber gaskets are correctly seated. |
| Leaks from Handle | Worn ceramic cartridge. | Contact KUZOR customer service for assistance or professional plumbing advice. |
| Pop-Up Drain Not Sealing | Debris in drain; improper installation of drain stopper. | Remove and clean the drain stopper. Reinstall the drain ensuring proper alignment and sealing. |
| No Hot/Cold Water | Water supply valve closed; reversed hot/cold connections. | Check that both hot and cold water supply valves are fully open. Verify hot and cold hoses are connected to the correct supply lines. |
