How To Change Out 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 money on professional plumbing services and give your bathroom a fresh, updated look.

Tools and Materials You'll Need:

New bathroom sink faucet

Adjustable wrench

Basin wrench

Plumber's putty

Teflon tape

Bucket

Screwdriver (optional)

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 flow. If your sink does not have accessible water supply valves, you will need to turn off the main water supply to your home.

2. Disconnect the Water Supply Lines:

Use an adjustable wrench to loosen the nuts connecting the water supply lines to the old faucet. Hold the faucet in place with your other hand to prevent it from turning. Once the nuts are loose, hand-tighten them the rest of the way.

3. Remove the Old Faucet:

Use a basin wrench to loosen the mounting nuts that secure the old faucet to the sink. Again, hold the faucet in place to keep it from rotating. Carefully lift the old faucet out of the sink.

4. Clean the Faucet Mounting Surface:

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

5. Apply Plumber's Putty and Install the New Faucet:

Roll a rope of plumber's putty and place it around the base of the new faucet. Make sure the putty creates a watertight seal between the faucet and the sink.

Insert the new faucet into the sinkhole and tighten the mounting nuts hand-tight. Use the basin wrench to further tighten the nuts, but be careful not to overtighten and damage the faucet.

6. Connect the Water Supply Lines:

Apply Teflon tape to the threads of the new faucet's water supply connections. Screw the water supply lines onto the faucet and tighten them with an adjustable wrench. Make sure the connections are snug, but again, avoid overtightening.

7. Turn on the Water Supply and Check for Leaks:

Slowly turn on the water supply valves under the sink or at the main water supply. Check the connections for any leaks. If you find any, tighten the nuts slightly until the leak stops.

8. Install the Handle and Pop-Up Drain (Optional):

Depending on the type of faucet you have, you may need to install a handle and pop-up drain. Follow the manufacturer's instructions for proper installation.

Tips:

Use a flashlight to inspect hard-to-reach areas for leaks.

If you are replacing a widespread faucet, you will need to measure the distance between the handle holes before installing the new faucet to ensure proper alignment.

Consider hiring a professional plumber if you have any doubts about your ability to complete the project safely and correctly.
