Step 3: Disconnect the Old Faucet (if applicable) 

If you’re replacing an existing faucet, use an adjustable wrench to disconnect the supply lines (hot and cold) from the old faucet. 

Also, disconnect the faucet from the sink or countertop. Make sure to catch any remaining water in a bucket or with a towel.

Step 4: Remove the Old Faucet 

Unscrew the mounting nuts that secure the old faucet to the sink or countertop. Lift the old faucet out.

Most touchless faucets require a power source, usually batteries or an electrical outlet. Follow the manufacturer’s instructions to connect the power supply. For battery-powered faucets, install the batteries in the control box.

How to Maintain Your Touchless Faucet After Installation

Maintaining a touchless faucet is essential to ensure it continues to work properly and remains hygienic. Here are some maintenance tips for a touchless faucet after installation:

1. Regular Cleaning

Wipe down the faucet with a damp cloth regularly to remove water spots, fingerprints, and any residue. Use a mild, non-abrasive cleaner if necessary.

Avoid harsh or abrasive cleaners, which can damage the faucet’s finish.

2. Avoid Chemicals

Avoid using harsh chemicals or abrasive pads on the faucet, as they can damage the finish and sensor.

3. Inspect for Leaks

Periodically check for any leaks around the base of the faucet or at the supply line connections. If you notice leaks, tighten the connections or replace any faulty components as needed.

4. Check the Batteries (If Applicable)

If your touchless faucet is battery-operated, monitor the battery life. Replace the batteries as needed to ensure the sensor functions correctly. Most touchless faucets will give you an indicator when the batteries are low.

5. Clean the Sensor Eye

The sensor is a critical component of the touchless faucet. Keep the sensor eye clean and free from obstructions.

Use a soft, damp cloth to wipe it down and remove any buildup that may affect its performance.

6. Inspect the Control Box

Check the control box regularly to ensure it is securely mounted and free from debris. Make sure the wires and connections are not damaged or loose.

7. Maintain the Water Supply Lines

Periodically inspect the water supply lines for signs of wear or damage. If you notice any issues, replace the supply lines as necessary.

8. Maintain the Solenoid Valve

The solenoid valve is a key component of the touchless system. 

While it typically requires little maintenance, it’s essential to keep it free from debris or mineral buildup that may affect its operation. 

If you notice reduced water flow or erratic behavior, you may need to clean or replace the solenoid valve.

9. Consult the Manufacturer’s Manual

Refer to the manufacturer’s manual or instructions that came with your touchless faucet for specific maintenance guidelines. Manufacturers may have unique recommendations for their products.

10. Address Issues Promptly

If you encounter any issues with your touchless faucet, such as reduced water flow, inconsistent sensor response, or unusual sounds, address them promptly. It’s best to troubleshoot and resolve problems early to prevent more significant issues.

11. Schedule Professional Service

If you are unsure about how to maintain or repair your touchless faucet, or if you encounter complex issues, consider consulting a professional plumber or the faucet manufacturer’s customer support for assistance.
