Installation
The HOIGY Waterfall Bathroom Sink Faucet is designed for quick and easy installation, typically within 10 minutes, without requiring specialized tools or a plumber. It is compatible with 3-hole basins ranging from 4 to 10 inches, with a sink hole diameter of 1.1-1.5 inches and a sink thickness of 0.1-1.9 inches.
Installation Steps:
- Insert the Faucet: Place the faucet spout and handles into the designated holes on your sink or countertop.
- Secure with Plastic Nut: From underneath the sink, screw the plastic nuts onto the threaded shafts of the faucet components to secure them in place.
- Connect Snap-on Connector: Attach the water supply hoses to the faucet and then connect them to the included snap-on connector. Ensure a secure fit to prevent leaks.
- Connect Angle Valves: Connect the other ends of the water supply hoses to your hot and cold angle stop valves.
The package includes all necessary components: the faucet, 20.5-inch 3/8" water supply hoses, a pop-up drain, and installation hardware. The water hoses are pre-connected to the vanity faucet to minimize potential leakage points during installation.

Pop-Up Drain Installation:
The included pop-up drain is designed for easy installation and features a press mechanism that prevents sticking and water accumulation. It is compatible with sink holes between 1.6-1.9 inches and sink thicknesses between 1.2-2.4 inches. Ensure your sink has an overflow if using the overflow-compatible drain.

Operating Instructions
Your HOIGY faucet features two lever handles for independent control of hot and cold water. The left handle typically controls hot water, and the right handle controls cold water. Adjusting the handles allows you to achieve your desired water temperature and flow rate.
- Water Flow: Turn the handles upwards to open the water flow.
- Temperature Control: Rotate the left handle for hotter water and the right handle for colder water. Adjust both handles simultaneously to mix water to your preferred temperature.
- Waterfall Spout: The unique waterfall spout delivers a steady, laminar stream of water, enhanced by a 3-layer metal filter and built-in pressure reducing valve to prevent splashing and conserve water.

Maintenance
To ensure the longevity and appearance of your HOIGY faucet, follow these simple maintenance guidelines:
- Cleaning: Clean the faucet regularly with a soft cloth and mild soap. Avoid abrasive cleaners, harsh chemicals, or scouring pads, as these can damage the matte black finish. The upgraded surface material resists fingerprints and water spots, making cleaning easier.
- Filter Maintenance: Periodically check the 3-layer metal filter in the spout for any debris or mineral buildup. If necessary, gently remove and clean the filter to maintain optimal water flow.
- Leak Prevention: Regularly inspect connections for any signs of leaks. The faucet's design, including the high-sealing ceramic valve core and nylon braided supply hoses with snap-on connectors, is engineered for leak-free performance.

Troubleshooting
If you encounter any issues with your HOIGY faucet, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Water Leakage | Loose connections, damaged O-rings, ceramic valve issue. | Check all connections, especially the snap-on connector and angle valve connections. Ensure they are tightened correctly. The faucet features a high-sealing ceramic valve core and durable nylon braided hoses designed to prevent leaks. If leaks persist, contact customer service. |
| Low Water Flow | Clogged filter, low water pressure, kinked supply hose. | Inspect the 3-layer metal filter in the spout for debris and clean if necessary. Check your household water pressure. Ensure supply hoses are not kinked. |
| Handles Stiff or Difficult to Turn | Mineral buildup, internal component issue. | Clean around the base of the handles. If the issue persists, contact customer service. |
| Pop-Up Drain Not Functioning | Debris, improper installation. | Clear any debris from the drain mechanism. Re-check installation to ensure proper alignment. |
