5. Test for Leaks
Once installed, slowly turn on the main water supply and check all connections for any signs of leaks. Run the faucet for a few minutes to flush the lines.
Operating Instructions
Your FORIOUS kitchen faucet features a single-handle control for water temperature and flow, along with a versatile pull-down sprayer offering five distinct spray modes.

Maintenance
Regular maintenance will ensure the longevity and optimal performance of your FORIOUS faucet.
1. Cleaning the Faucet Finish
The matte black finish is fingerprint-resistant and easy to clean. Use a soft, damp cloth and mild soap to wipe down the faucet. Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the finish. Wipe dry with a clean cloth to prevent water spots.
2. Cleaning Silicone Nozzles
The silicone nozzles on the sprayer head are designed for easy cleaning. If mineral buildup occurs, simply flex the silicone nozzles with your fingers to dislodge any deposits. This ensures consistent spray performance.
3. Internal Components
The faucet features a durable ceramic disc valve, tested for 500,000 cycles, ensuring smooth operation and drip-free performance. The PEX hoses are food-grade and designed for high temperature resistance and superior durability, contributing to leak-proof performance.
