Installation (Setup)
Before you begin, ensure the main water supply is turned off. Clear the area under the sink for easy access.
Tools You May Need:
- Adjustable Wrench
- Phillips Head Screwdriver
- Plumber's Putty or Silicone Sealant
- Flashlight
- Bucket and Towel
Installation Steps:
- Prepare the Sink: If installing on a 3-hole sink, place the deck plate over the holes. For a 1-hole sink, the deck plate is optional.
- Install the Faucet: Insert the faucet body through the hole(s) in the sink or deck plate. Ensure the faucet is centered and facing the correct direction.
- Secure the Faucet: From underneath the sink, slide the rubber washer, metal washer, and mounting nut onto the threaded shank of the faucet. Hand-tighten the mounting nut, then use a wrench to secure it firmly, but do not overtighten.
- Connect Supply Lines: Attach the hot and cold supply lines (included) to the corresponding inlets on the faucet. Connect the other ends of the supply lines to your hot and cold water shut-off valves. Ensure connections are tight to prevent leaks.
- Install Pop-up Drain: Apply plumber's putty or silicone sealant around the flange of the pop-up drain. Insert the drain body into the sink drain hole. From underneath, secure the drain with the provided washer and nut. Connect the drain to your P-trap assembly.
- Test for Leaks: Slowly turn on the main water supply. Check all connections for leaks. If leaks occur, tighten the connections as needed.

Maintenance
Proper care and maintenance will ensure the longevity and appearance of your GBBNE faucet.

- Spout Cleaning: Periodically check the waterfall spout for mineral buildup. If necessary, gently clean with a soft brush and a vinegar solution.
- Leak Checks: Periodically inspect all connections under the sink for any signs of leaks. Tighten connections if needed.
Troubleshooting
