How To Replace A Bathroom Sink Faucet

Replacing a bathroom sink faucet is a relatively simple plumbing project that can be completed in a few hours. By following these step-by-step instructions, you can save yourself the cost of hiring a plumber.

Tools and Materials You'll Need:

New bathroom sink faucet
Adjustable wrench
Basin wrench
Plumber's putty
Teflon tape
Flashlight (optional)

Step-by-Step Instructions:

1. Turn Off the Water Supply:

Locate the water supply valves beneath the sink and turn them clockwise to shut off the water. If there are no valves, you will need to turn off the main water supply to your home.

2. Disconnect the Old Faucet:

Use the adjustable wrench to loosen the nuts that hold the water supply lines to the faucet. Be careful not to overtighten. Once the nuts are loose, you can disconnect the water supply lines by hand.

Next, use the basin wrench to loosen the nuts that hold the faucet to the sink. Once the nuts are loose, you can lift the faucet off the sink.

3. Clean the Sink Surface:

Use a cloth or sponge to clean the surface of the sink where the new faucet will be installed. Remove any old plumber's putty or debris.

4. Apply Plumber's Putty:

Roll out a small piece of plumber's putty into a rope. Place the rope around the base of the new faucet, making sure to create a watertight seal.

5. Install the New Faucet:

Place the new faucet over the hole in the sink and align it correctly. Tighten the nuts that hold the faucet to the sink using the basin wrench. Be careful not to overtighten.

6. Reconnect the Water Supply Lines:

Wrap the threads of the water supply lines with Teflon tape to create a watertight seal. Screw the water supply lines onto the faucet by hand, then tighten them using the adjustable wrench.

7. Turn On the Water Supply:

Slowly turn on the water supply valves beneath the sink or turn on the main water supply to your home. Check for leaks around the base of the faucet and the water supply lines.

8. Adjust the Faucet:

Use the adjustable wrench to adjust the position of the faucet as needed. You may also need to adjust the handles to ensure that the water flows smoothly.

Tips:

If you are not comfortable working with plumbing, it is best to hire a qualified plumber.
Be sure to purchase a new faucet that is compatible with your sink and water supply lines.
Use a flashlight to inspect the underside of the sink for any leaks.
Tighten all nuts and bolts securely, but do not overtighten.
