Maintenance
Regular cleaning and maintenance will help preserve the appearance and functionality of your Schock faucet.
- Cleaning the Surface: Clean the faucet regularly with a soft cloth and mild soap. Rinse thoroughly with clean water and dry with a soft cloth to prevent water spots.
- Avoid Harsh Cleaners: Do not use abrasive sponges, scouring pads, or cleaners containing alcohol, ammonia, bleach, or other harsh chemicals, as these can damage the lacquered finish.
- Aerator Maintenance: Periodically unscrew the aerator from the spray head and clean any mineral deposits or debris. Rinse and reattach.
- Hose Inspection: Occasionally inspect the pull-out hose for any signs of wear or damage.
Troubleshooting
If you encounter any issues with your faucet, refer to the following common troubleshooting tips:
- Low Water Flow: Check if the aerator is clogged with debris or mineral deposits. Clean it as described in the Maintenance section. Ensure water supply valves are fully open.
- Leaks from Connections: Turn off the water supply and carefully tighten any loose connections. If the leak persists, check the seals and O-rings for damage and replace if necessary.
- Dripping Faucet: A dripping faucet often indicates a worn-out cartridge. Contact customer support for replacement parts or professional assistance.
- Difficulty Switching Spray Modes: Ensure the spray head button is not stuck or obstructed. Clean the spray head if necessary.
