Step-by-Step Installation Guide
This guide assumes a standard two-handle bathroom faucet installation. The steps may vary slightly depending on your specific faucet model. Always refer to your faucet's instruction manual for detailed guidance.
1. Turn Off the Water Supply
This is crucial! Locate the shut-off valves under the sink for both hot and cold water lines. Turn them clockwise until they're completely closed. Turn on the faucet briefly to relieve any remaining pressure in the lines.
2. Disconnect the Old Faucet
- Remove the faucet handles: Usually, there are small screws underneath or on the side of the handles. Unscrew these and remove the handles.
- Disconnect the water supply lines: Use adjustable wrenches to carefully loosen and disconnect the hot and cold water supply lines from the old faucet. Have your bucket ready to catch any dripping water.
- Disconnect the drain assembly: This may involve loosening nuts connecting the faucet's tailpiece to the drain assembly.
- Remove the faucet mounting nuts: Using a basin wrench, carefully unscrew the mounting nuts securing the faucet to the sink. Remove the old faucet.
3. Clean the Sink Surface
Carefully remove any old putty or sealant from the sink surface where the old faucet was mounted. A putty knife or flathead screwdriver works well for this. Clean the area thoroughly.
4. Prepare the New Faucet
- Apply Plumber's Putty: Apply a small amount of plumber's putty to the base of the new faucet, creating a watertight seal. Follow the manufacturer's instructions for proper application.
- Install the new faucet: Carefully place the new faucet into the sink's mounting holes.
- Secure the faucet with mounting nuts: Using the basin wrench, tighten the mounting nuts to secure the faucet firmly to the sink. Don't overtighten!
5. Connect the Water Supply Lines
- Wrap Teflon Tape: Wrap Teflon tape around the threads of the new faucet's supply line connections. This helps create a watertight seal and prevents leaks.
- Attach the Water Supply Lines: Connect the hot and cold water supply lines to the new faucet. Tighten securely with adjustable wrenches.
6. Connect the Drain Assembly
Reconnect the drain assembly to the new faucet, ensuring all connections are tight and secure.
7. Turn On the Water Supply
Slowly turn the hot and cold water supply valves counterclockwise. Check carefully for any leaks around the faucet and supply lines. Tighten any connections as needed.
8. Test the Faucet
Turn the faucet on and off several times to ensure proper operation. Check for any leaks.
Troubleshooting
If you encounter leaks, double-check all connections, paying close attention to the tightness of the nuts and the effectiveness of the Teflon tape. If the problem persists, consult a qualified plumber.
By following these steps, you can successfully install your new bathroom faucet and enjoy a refreshed bathroom. Remember safety first, and always consult your faucet's instructions for specific guidance.
