3. Setup (Installation)
Professional installation is recommended for optimal performance and to ensure compliance with local plumbing codes. Before beginning, ensure you have all necessary tools and components.

- Plumber's putty or silicone sealant
- Flashlight

3.2 Pre-Installation Steps

- Clear the area under the sink for easy access.
- Remove your old faucet, if applicable. Clean the mounting surface thoroughly.
3.3 Faucet Installation

- From underneath the sink, secure the faucet using the provided mounting hardware (washer and mounting nut). Tighten firmly but do not overtighten.

5. Maintenance
Regular maintenance will help preserve the finish and functionality of your Waterstone faucet.
5.1 Cleaning the Faucet
- Clean the faucet regularly with a soft, damp cloth.
- For matte finishes, avoid abrasive cleaners, harsh chemicals, or polishing agents, as these can damage the finish.
- Wipe dry after cleaning to prevent water spots.
5.2 Aerator Maintenance
- If water flow decreases or becomes irregular, the aerator may be clogged.
- Unscrew the aerator from the spray head.
- Rinse any debris from the screen. For stubborn mineral deposits, soak the aerator in a 50/50 solution of white vinegar and water.
- Reattach the aerator, ensuring it is securely tightened.
