4. Maintenance
Regular cleaning and maintenance will ensure the longevity and optimal performance of your faucet.
- Cleaning: Clean the faucet regularly with a soft cloth and mild soap. Avoid using abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the matte black finish.
- Water Spots: To prevent water spots, wipe the faucet dry after each use.
- Aerator Maintenance: Periodically unscrew and clean the aerator (located at the tip of the spout) to remove any mineral buildup or debris that may affect water flow.

5. Troubleshooting
If you encounter any issues with your faucet, refer to the common troubleshooting tips below.
- Low Water Flow: Check if the aerator is clogged with debris or mineral deposits. Clean or replace the aerator if necessary. Ensure both hot and cold water supply valves are fully open.
- Leaks from Faucet Base: Verify that all mounting hardware is securely tightened. Check the O-rings and gaskets for proper seating and damage.
- Dripping Faucet: A dripping faucet usually indicates an issue with the ceramic disc cartridge. While the faucet uses a drip-free cartridge, if dripping occurs, ensure it is properly installed or consider replacing it if damaged.
- Water Temperature Issues: Ensure both hot and cold water supply lines are connected correctly and that the water heater is functioning properly.
