How To Install A New Faucet In Bathroom Sink

Replacing a bathroom 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 faucet
Adjustable wrench
Plumber's putty
Teflon tape
Flashlight
Bucket or bowl
Screwdriver (if necessary)

Step 1: Turn Off the Water Supply

Before you begin, turn off the water supply to the bathroom sink. There will be two shut-off valves located under the sink, one for hot water and one for cold water. Turn each valve clockwise until it is fully closed.

Step 2: Disconnect the Old Faucet

Once the water supply is turned off, use an adjustable wrench to disconnect the water supply lines from the old faucet. Then, use a flashlight to locate the mounting nuts that hold the faucet in place. Loosen these nuts with the adjustable wrench and remove the old faucet.

Step 3: Apply Plumber's Putty

Apply a ring of plumber's putty around the base of the new faucet. This will help to create a watertight seal between the faucet and the sink.

Step 4: Install the New Faucet

Place the new faucet in the sink and tighten the mounting nuts. Be sure to tighten the nuts evenly to avoid damaging the faucet or the sink.

Step 5: Connect the Water Supply Lines

Wrap a few layers of Teflon tape around the threads of the water supply lines. Then, connect the water supply lines to the new faucet. Tighten the nuts by hand, then use the adjustable wrench to tighten them further. Do not overtighten the nuts.

Step 6: Turn on the Water Supply

Turn on the water supply to the bathroom sink. Check for leaks around the base of the faucet and at the water supply lines. If you see any leaks, tighten the nuts further.

Step 7: Test the Faucet

Turn on the new faucet and let it run for a few minutes. Check for leaks and make sure that the water temperature is correct. If everything is working properly, you have successfully installed the new faucet.

Tips:

If you are not comfortable working with plumbing, it is best to hire a licensed plumber.
Before you start, make sure that you have all of the necessary tools and materials.
Be careful not to overtighten the nuts, as this can damage the faucet or the sink.
If you see any leaks, tighten the nuts further until the leak stops.
