How To Replace A Three Piece Bathroom Faucet

Replacing a three-piece 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 and have your new faucet installed in no time.

Before you begin, gather all of the necessary tools and materials. You will need a new three-piece bathroom faucet, a basin wrench, a pair of pliers, a screwdriver, and some plumber's putty.

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 under the sink, one for the hot water and one for the cold water. Turn both valves clockwise until they are fully closed.

Step 2: Remove the old faucet.

Once the water supply is turned off, you can remove the old faucet. Use the basin wrench to loosen the nuts that hold the faucet in place. Be careful not to overtighten the nuts, as this can damage the faucet.

Step 3: Install the new faucet.

Apply a thin bead of plumber's putty to the base of the new faucet. This will help to create a watertight seal. Place the new faucet in place and tighten the nuts until they are snug.

Step 4: Connect the water supply lines.

Connect the water supply lines to the new faucet. The hot water line should be connected to the red valve and the cold water line should be connected to the blue valve. Tighten the nuts on the water supply lines until they are snug.

Step 5: Turn on the water supply.

Slowly turn on the water supply valves under the sink. Check for any leaks. If you see any leaks, tighten the nuts on the faucet or water supply lines until the leak stops.
