Tools and Materials Needed:

Adjustable wrench

Basin wrench
New Moen single handle bathroom faucet
Teflon tape
Plumber's putty (optional)

Step-by-Step Instructions:

1. Shut Off the Water Supply

Locate the shutoff valves underneath the sink and turn them clockwise to close them. If your sink doesn't have shutoff valves, you'll need to turn off the main water supply to your home.

2. Disconnect the Water Lines

Using an adjustable wrench, loosen the nuts connecting the water supply lines to the old faucet. Remove the old faucet by gently pulling it straight up.

3. Remove the Old Faucet Handle

Locate the set screw on the top of the faucet handle and remove it with a Phillips screwdriver. Pull the handle straight up to remove it.

4. Disconnect the Cartridge

Using an adjustable wrench, loosen the nut that secures the cartridge to the faucet body. Carefully remove the old cartridge.

5. Install the New Cartridge

Insert the new cartridge into the faucet body and hand-tighten the nut. Avoid overtightening.

6. Reattach the Handle

Place the new handle on the faucet stem and tighten the set screw with a Phillips screwdriver.

7. Connect the Water Lines

Wrap Teflon tape around the threads of the new faucet supply lines and hand-tighten them into the corresponding ports on the faucet body. Use an adjustable wrench to fully tighten the nuts.

8. Apply Plumber's Putty (Optional)

Optional: For added leak protection, apply a thin layer of plumber's putty around the base of the faucet before setting it in place.

9. Install the Faucet

Place the faucet in the sink hole and tighten the mounting nuts from underneath the sink with a basin wrench.

10. Turn on the Water Supply

Slowly turn on the shutoff valves or main water supply and check for any leaks. Tighten any loose connections as necessary.

Tips:

Use caution when tightening the nuts and bolts, as overtightening can damage the faucet.
If the old cartridge is stuck, you may need to use a wrench to remove it.
Replace the aerator if it is clogged or damaged.
If you encounter any leaks, tighten the connections or apply additional Teflon tape.

By following these instructions carefully, you can successfully replace your Moen single handle bathroom faucet and enjoy a refreshed and updated look.
