How to resolve a Moen leaking bathroom faucet: Step-by-Step guide

Bathroom faucets can develop leaks over time due to various reasons, such as worn-out parts, improper installation, or mineral buildup. If your Moen bathroom faucet is leaking, it is important to address it promptly to prevent water damage and unnecessary water wastage. Here's a step-by-step guide to help you fix a leaking Moen bathroom faucet:

Materials required:

Replacement cartridge
Faucet handle removal tool
Adjustable wrench
Plumber's putty
Soft cloths

Step 1: Turn off the water supply

Before starting any repairs, turn off the water supply valves located beneath the sink. This will prevent water from flowing into the faucet while you work.

Step 2: Remove the faucet handle

Use the faucet handle removal tool to remove the handle from the faucet. If it is difficult to remove, apply some penetrating oil to loosen it.

Step 3: Remove the cartridge

Once the handle is removed, you will see the cartridge. Use an adjustable wrench to loosen and remove the cartridge.

Step 4: Inspect the cartridge

Inspect the cartridge for any signs of damage, corrosion, or mineral buildup. If the cartridge is damaged, it will need to be replaced.

Step 5: Install the new cartridge

Apply a thin layer of plumber's putty to the base of the new cartridge and insert it into the faucet body. Tighten the cartridge using an adjustable wrench.

Step 6: Reinstall the faucet handle

Place the faucet handle over the cartridge stem and tighten it using the faucet handle removal tool.

Step 7: Turn on the water supply

Turn on the water supply valves beneath the sink and check if the faucet is still leaking. If the leak has not been resolved, repeat the steps above to ensure that the cartridge was installed correctly.

Step 8: Clean the faucet

Use a soft cloth to wipe away any water or debris from the faucet and surrounding area.

Additional Tips

1. If the leak is coming from the base of the faucet, you may need to replace the O-rings or washers. 2. If the leak is coming from the spout, you may need to replace the aerator or the spout itself. 3. If you are not comfortable making these repairs yourself, it is best to call a qualified plumber for assistance.
