How To Change Out Bathroom Faucet

Replacing a bathroom faucet is a relatively simple plumbing task that can be completed in a few hours with the right tools and materials. Here's a step-by-step guide on how to do it:

Materials you'll need:

New bathroom faucet
Adjustable wrench
Plumber's putty
Teflon tape
Basin wrench
Bucket
Old towels or rags

Step 1: Turn off the water supply

Before you start working on the faucet, you need to turn off the water supply to the bathroom. There should be two shut-off valves under the sink, one for hot water and one for cold water. Turn both valves clockwise until they are completely closed.

Step 2: Disconnect the old faucet

Once the water supply is turned off, you can disconnect the old faucet. Use an adjustable wrench to loosen the nuts that are holding the faucet in place. Be careful not to overtighten the nuts, as you can damage the faucet or the sink.

Once the nuts are loose, you can remove the old faucet from the sink. Be sure to keep the old parts in case you need them for reference later.

Step 3: Clean the sink surface

Before you install the new faucet, it's important to clean the surface of the sink. Use a damp cloth to wipe away any dirt or debris. You can also use a mild cleanser to clean the surface if it's particularly dirty.

Step 4: Apply plumber's putty

Once the sink surface is clean, you can apply plumber's putty to the base of the new faucet. Plumber's putty is a moldable material that helps to create a watertight seal between the faucet and the sink.

To apply plumber's putty, simply roll it into a rope and then place it around the base of the faucet. Be sure to press the putty into place so that it creates a good seal.

Step 5: Install the new faucet

Once the plumber's putty is in place, you can install the new faucet. Place the faucet over the hole in the sink and then tighten the nuts that are holding it in place. Be sure to tighten the nuts until they are snug, but do not overtighten them.

Step 6: Connect the water supply lines

Once the faucet is installed, you can connect the water supply lines. Use Teflon tape to wrap the threads of the water supply lines before you connect them to the faucet. This will help to create a watertight seal.

Once the water supply lines are connected, turn on the water supply and check for leaks. If there are any leaks, tighten the nuts that are holding the water supply lines in place.

Step 7: Test the faucet

Once the water supply lines are connected, you can test the faucet to make sure that it is working properly. Turn on the hot and cold water and check for any leaks. If there are any leaks, tighten the nuts that are holding the faucet in place.

Once you have tested the faucet and made sure that it is working properly, you can finish up the installation by wiping away any excess water and debris.
