How To Change A Single Handle Bathroom Faucet

Replacing a single-handle bathroom faucet is a relatively simple plumbing project that can be completed in a few hours. Whether you're a seasoned DIYer or a complete novice, following these step-by-step instructions will guide you through the process, ensuring a successful installation.

Tools and Materials Required:

Adjustable wrench
Faucet wrench
Channel-lock pliers
New single-handle faucet
Plumber's putty
Teflon tape
Basin wrench (optional)

Step-by-Step Instructions:

1. Turn off the Water Supply: Locate the water supply valves under the sink. Turn the hot and cold water valves clockwise to关闭them.

2. Disconnect the Water Lines: Using an adjustable wrench, loosen the water supply lines that connect to the faucet. Hold the nuts on the faucet with a faucet wrench to prevent them from turning. Disconnect the lines by hand.

3. Remove the Old Faucet: Use an adjustable wrench to loosen and remove the mounting nut that secures the faucet to the sink. Lift the old faucet straight up to detach it from the sink.

4. Clean the Mounting Surface: Remove any old plumber's putty or debris from the sink mounting surface. Clean the area with a damp cloth.

5. Apply Plumber's Putty: Roll out a thin bead of plumber's putty and create a circle around the base of the new faucet. Press the putty into place to form a seal.

6. Install the New Faucet: Carefully position the new faucet over the mounting surface and align the water supply holes. Press down firmly to set the putty.

7. Secure the Mounting Nut: Tighten the mounting nut by hand until snug. Then, use an adjustable wrench to fully tighten the nut, but avoid overtightening.

8. Connect the Water Lines: Hand-tighten the water supply lines onto the faucet. Use an adjustable wrench to tighten them further, but only until snug.

9. Wrap Teflon Tape: Apply two to three layers of Teflon tape clockwise around the threads of the spray hose. This will help prevent leaks.

10. Install the Spray Hose: Attach the spray hose to the faucet outlet and tighten it securely.

11. Test the Faucet: Turn on the water supply valves and slowly open the faucet. Check for any leaks around the base of the faucet, the water supply lines, and the spray hose connection. If you notice any leaks, tighten the connections accordingly.

12. Finish Up: Insert the aerator into the faucet outlet and tighten it by hand. Clean up any excess plumber's putty or water spills.

Tips:

Before starting, ensure you have all the necessary tools and a new faucet that is compatible with your sink.
If you encounter any stubborn nuts or bolts, use penetrating oil to loosen them.
Be careful not to overtighten any connections, as this can damage the fittings.
If you are not confident in your DIY skills, it's always advisable to consult a professional plumber.

Conclusion:

Replacing a single-handle bathroom faucet is a straightforward task that can give your bathroom a fresh and updated look. By following these detailed instructions, you can successfully install a new faucet and enjoy the benefits of a functional and stylish bathroom.
