How To Change A 3 Hole Bathroom Faucet

How to Change a 3-Hole Bathroom Faucet: A Step-by-Step Guide

Replacing a bathroom faucet is a common home improvement task that can save you money and improve the functionality of your bathroom. While it may seem like a daunting task, changing a 3-hole faucet is relatively straightforward if you follow the steps outlined below.

Before you begin, gather the following tools and materials:

Adjustable wrench
Pliers
Screwdriver
Faucet cleaner
Plumber's putty
New faucet
Thread sealant tape

Step 1: Turn off the Water Supply

The first step is to turn off the water supply to the faucet. Typically, there are two shut-off valves located under the sink, one for the hot water line and one for the cold water line. Turn both valves clockwise until they are completely closed.

Step 2: Disconnect the Water Lines

Once the water supply is turned off, disconnect the water lines that are connected to the faucet. Use an adjustable wrench to loosen the nuts that hold the water lines to the faucet. Be careful not to overtighten the nuts as you may damage the water lines.

Step 3: Remove the Old Faucet

Using pliers, remove the nuts that hold the faucet in place. Once the nuts are removed, lift the faucet straight up to detach it from the sink. Be careful as there may be some residual water in the faucet.

Step 4: Clean the Sink Surface

Before installing the new faucet, clean the surface of the sink where the faucet will be mounted. Use a faucet cleaner and a damp cloth to remove any dirt or debris. This will ensure a good seal between the faucet and the sink.

Step 5: Apply Plumber's Putty

Apply a thin bead 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 6: Install the New Faucet

Place the new faucet into the hole in the sink and align the holes in the faucet with the holes in the sink. Push down on the faucet to compress the plumber's putty and create a seal. Secure the faucet in place with the nuts that you removed earlier.

Step 7: Wrap Thread Sealant Tape on Water Lines

Wrap thread sealant tape around the threads of the water lines that will connect to the faucet. This will help to prevent leaks and ensure a tight connection.

Step 8: Connect the Water Lines

Connect the water lines to the faucet by tightening the nuts that hold them in place. Use an adjustable wrench to tighten the nuts, but be careful not to overtighten them.

Step 9: Turn on the Water Supply

Turn on the water supply to the faucet by opening the shut-off valves under the sink. Check for any leaks around the faucet and tighten any loose connections as needed.

Step 10: Finish the Installation

Once you have checked for leaks, install the handles and any other decorative pieces that came with the faucet. Your new 3-hole bathroom faucet is now installed and ready to use.

If you encounter any problems while changing your bathroom faucet, do not hesitate to seek the advice of a professional plumber. A plumber can help you troubleshoot any issues and ensure that your faucet is installed correctly.
