How to Replace a One Piece Bathroom Faucet

Replacing a one-piece bathroom faucet is a relatively straightforward task that can be completed in about an hour. By following these steps, you can save yourself the cost of hiring a plumber.

Tools and Materials You'll Need

Adjustable wrench
Basin wrench
Pliers
Screwdriver
New faucet
Plumber's putty
Teflon tape

Step 1: Turn Off the Water Supply

The first step is to turn off the water supply to the faucet. There will be two shut-off valves located under the sink. Turn both valves clockwise to close them.

Step 2: Remove the Old Faucet

Use an adjustable wrench to loosen the nuts that hold the faucet in place. Be careful not to overtighten the nuts, as this can damage the faucet.

Once the nuts are loose, you can remove the faucet by pulling it straight up. Make sure to hold onto the faucet with both hands, as it may be heavy.

Step 3: Clean the Surface

Before installing the new faucet, clean the surface of the sink where the faucet will be mounted. Use a damp cloth to wipe away any dirt or debris.

Step 4: Apply Plumber's Putty

Apply a thin layer of plumber's putty to the underside of the new faucet. This will help to create a watertight seal between the faucet and the sink.

Step 5: Install the New Faucet

Place the new faucet on the sink and align it with the holes. Push the faucet down until it is flush against the sink.

Use an adjustable wrench to tighten the nuts that hold the faucet in place. Again, be careful not to overtighten the nuts.

Step 6: Connect the Water Supply Lines

Connect the water supply lines to the faucet. Use a basin wrench to tighten the nuts on the supply lines. Do not overtighten the nuts, as this can damage the supply lines.

Step 7: Turn On the Water Supply

Once the water supply lines are connected, turn on the water supply valves under the sink. Check for leaks around the faucet and supply lines.

If there are any leaks, turn off the water supply and tighten the nuts on the faucet or supply lines. Once the leaks are stopped, turn on the water supply again.

Step 8: Test the Faucet

Test the faucet to make sure it is working properly. Turn on the hot and cold water taps and check for any leaks or uneven flow.

If the faucet is working properly, you have successfully replaced your one-piece bathroom faucet.
