How To Replace A Single Handle Bathtub Faucet In 5 Easy Steps!

Replacing a single handle bathtub faucet may seem like a daunting task, but with the right tools and a bit of know-how, it can be a manageable DIY project. Follow this comprehensive guide to learn the essential steps involved in this plumbing endeavor.

Gather Your Tools and Materials

Before embarking on this project, ensure you have the necessary tools and materials:

• Adjustable wrench
• Allen wrench (if required)
• Basin wrench
• Channel lock pliers
• Flashlight
• Gloves
• New single handle bathtub faucet
• Plumber’s tape
• Towels or rags
• Safety glasses

Step 1: Shut Off the Water Supply

Safety first! Locate the water supply valves beneath the sink or behind the bathtub and turn them off completely. Check if the water flow has stopped by turning on the faucet.

Step 2: Remove the Decorative Cap

The decorative cap on the handle conceals the screws that hold it in place. Using a flashlight, locate the small set screw and remove it with an Allen wrench. If there is no set screw, gently pry off the cap with a flathead screwdriver or your fingernails.

Step 3: Unscrew the Handle

Once the cap is removed, reveal the handle screws. Use an adjustable wrench to loosen these screws and detach the handle from the faucet body.

Step 4: Disconnect the Supply Lines

Beneath the handle, you’ll find the supply lines that connect the faucet to the water source. Use a basin wrench to carefully loosen these lines. Place a towel or rags underneath to catch any dripping water.

Step 5: Remove the Faucet Body

With the supply lines disconnected, you can now remove the faucet body. Use an adjustable wrench to loosen the mounting nuts that secure the faucet to the tub deck. Gently pull the faucet upwards and out of the tub.

Step 6: Install the New Faucet

Place the new faucet body into the tub deck and tighten the mounting nuts. Hand-tighten them as much as possible, then use an adjustable wrench to further tighten them by a quarter turn.

Step 7: Reconnect the Supply Lines

Attach the supply lines to the new faucet body and tighten them using a basin wrench. Ensure they are connected securely but avoid overtightening.

Step 8: Install the Handle

Slide the handle onto the faucet body and align it properly. Tighten the handle screws using an adjustable wrench. Reinstall the decorative cap and tighten the set screw, if applicable.

Step 9: Turn on the Water Supply

Slowly turn on the water supply valves and check for any leaks. If you notice any drips, tighten the connections as needed.

Troubleshooting Tips

• Loose handle: Tighten the handle screws using an adjustable wrench.
• Leaking water: Check the connections of the supply lines and faucet body. Tighten them if necessary.
• Water flow issues: Ensure the supply lines are not kinked or obstructed. Check the aerator for any debris.
• Difficult to remove faucet body: Use penetrating oil to loosen the mounting nuts. If they are still stuck, contact a plumber.

Final Note:

Replacing a single handle bathtub faucet is a rewarding DIY project that can save you both time and money. By following these detailed steps and troubleshooting tips, you can enjoy a fully functional and stylish bathroom fixture in no time.
