How To Change Bathroom Faucets

Changing a bathroom faucet is a relatively simple plumbing task 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

Before you begin, gather the following tools and materials:

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

Step-by-Step Instructions

1. Turn Off the Water Supply

Locate the water supply valves beneath the sink. Turn both the hot and cold water valves clockwise to shut off the water supply.

2. Remove the Old Faucet

Use the adjustable wrench to loosen the nuts that secure the faucet to the sink. Be careful not to overtighten the nuts, as this can damage the faucet or the sink.

Once the nuts are loose, use the basin wrench to unscrew the faucet from the sink. If the faucet is difficult to remove, you may need to use a flashlight to see better.

3. Clean the Sink Surface

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

4. Apply Plumber's Putty

Roll out a small piece of plumber's putty into a rope. Apply the putty to the underside of the new faucet, around the base of the faucet body.

5. Wrap Teflon Tape

Wrap Teflon tape around the threads of the water supply lines. This will help to create a watertight seal.

6. Connect the Water Supply Lines

Connect the water supply lines to the new faucet. Make sure to connect the hot water line to the hot water inlet and the cold water line to the cold water inlet.

7. Tighten the Nuts

Use the adjustable wrench to tighten the nuts that secure the faucet to the sink. Be careful not to overtighten the nuts.

8. Turn On the Water Supply

Turn on the water supply valves beneath the sink. Check for leaks around the base of the faucet and the water supply lines.

9. Adjust the Faucet

Adjust the faucet to the desired temperature and flow rate. You may need to use the adjustable wrench to adjust the handle or the set screw.

Tips

If you are not comfortable changing the faucet yourself, you can hire a plumber to do it for you.
Be sure to purchase a new faucet that is compatible with your sink.
If you have any questions, consult a plumbing professional.
