How To Change a 3-Handle Bathtub Faucet

Replacing a worn-out or leaky bathtub faucet is a common plumbing project that homeowners can often tackle themselves. While the process may seem daunting, with clear instructions and the right tools, you can successfully update your bathroom with a new 3-handle faucet. This article will guide you through the steps of removing your old faucet and installing a new one, providing helpful tips and safety precautions along the way.

Step 1: Gather Your Tools and Materials

Before embarking on this project, ensure you have all the necessary tools and materials. These include:

Adjustable wrench
Channel-lock pliers
Phillips head screwdriver
Flathead screwdriver
Plumbers tape
Basin wrench
New 3-handle bathtub faucet
New faucet supply lines (if needed)

It is recommended to have a bucket or basin handy to catch any water that may drain from the pipes during the process.

Step 2: Turn Off the Water Supply

Safety is paramount. Before disassembling any plumbing fixtures, ensure you turn off the water supply to the bathtub. This is typically located near the water meter or in the basement. Once you have turned off the water, run the faucet to drain any remaining water in the pipes.

Step 3: Disconnect the Old Faucet

Now you can begin removing the old faucet. First, use the adjustable wrench to loosen the nuts holding the faucet handles to the valve stems. Once the nuts are loose, remove the handles. Next, use the channel-lock pliers to remove the decorative escutcheons or plates that cover the faucet assembly.

For the faucet body, you may need to use a basin wrench to reach and loosen the nuts that secure it to the tub spout. These nuts are often difficult to access, so be patient and take your time. Once the nuts holding the faucet body are loose, gently pull it out from the tub spout.

Step 4: Remove the Old Supply Lines

The next step is to disconnect the old supply lines. These are the pipes that connect the faucet to the water supply. Use your adjustable wrench to loosen the nuts holding the supply lines to the faucet. Once the nuts are loose, remove the supply lines.

Step 5: Install the New Faucet

Now that the old faucet is removed, you can install the new faucet. Before attaching the faucet to the tub spout, wrap the threads of the faucet body with plumber's tape. This will help to prevent leaks. Next, carefully insert the new faucet body into the tub spout and secure it with the nuts you removed earlier.

Attach the new supply lines to the faucet, making sure to tighten the nuts securely. Remember to wrap the threads on the supply lines with plumber's tape as well. Once the supply lines are attached, connect the handles to the valve stems, ensuring they are properly aligned. You may need to use a Phillips head screwdriver to secure the handles to the stems.

Step 6: Turn on the Water and Check for Leaks

After installing the new faucet, turn the water supply back on. Once the water is flowing, check all connections for leaks. If you find any leaks, tighten the connections accordingly.

It is important to note that different brands and models of faucets may have unique installation instructions. Refer to the manual provided with your new faucet for specific guidance.
