4.2 Faucet Installation Steps
- Insert Faucet Stem: Insert the faucet stem into the drilled hole on your kitchen countertop.
- Secure from Underneath: From under the sink, place the mounting washer onto the faucet stem. Then, slip on the wing nut and tighten it securely to hold the faucet in place.
- Attach Quick-Connect Fitting: Choose the appropriate quick-connect fitting (1/4 inch or 3/8 inch) based on your PE tubing size. Screw the quick-connect fitting tightly onto the faucet stem. Ensure the black seal ring is properly placed on the bottom of the fitting before screwing it on.
- Connect PE Tubing: Insert your PE tubing into the push-in quick-connect fitting. Push firmly until it is fully seated.
- Secure with Lock Clip: Secure the tubing connection by inserting the blue lock clip into the fitting. This prevents accidental disconnection.
- Flush the System: Once all connections are made and the water purification system is connected, turn on the water supply. Flush the faucet for at least 1 minute to clear any air or debris. During this time, carefully check all connections for any leaks.

6. Maintenance
To ensure the longevity and optimal performance of your Waterdrop faucet, follow these maintenance guidelines:

- Leak Checks: Periodically inspect all connections under the sink for any signs of leaks. Tighten connections if necessary.
- Filter Replacement: Refer to your water purification system's manual for recommended filter replacement schedules. A clogged filter can reduce water flow.
7. Troubleshooting
If you encounter issues with your Waterdrop faucet, consider the following common solutions:
- Low Water Flow:
- Check if the water supply valve under the sink is fully open.
- Inspect your water purification system's filter. A clogged filter can significantly reduce flow. Replace if needed.
- Ensure there are no kinks or obstructions in the PE tubing.
- Leaks from Faucet Base or Connections:
- Turn off the water supply.
- Verify that the mounting washer and wing nut under the sink are securely tightened.
- Check the quick-connect fittings and ensure the PE tubing is fully inserted and secured with the blue lock clip.
- Ensure the black seal ring is correctly positioned within the quick-connect fitting.
- If leaks persist, contact customer support.
- Stiff Handle:
- Over time, mineral buildup can affect handle movement. Ensure regular cleaning.
- If the handle remains stiff, it may indicate an internal issue. Contact customer support.
