How to Fix a Leaky Bathroom Sink Faucet with Double Handles (Moen)

A leaky bathroom sink faucet can be a frustrating and costly problem. However, fixing a leaky Moen double handle faucet is a relatively simple task that can be completed in a few easy steps. Here's a comprehensive guide to help you fix your leaky faucet and restore your bathroom to its pristine condition.

1. Gather Essential Tools

Before you begin, gather the necessary tools for the job, including:

- Adjustable wrench - Allen wrench (hex key) - Plumber's putty - New washers or O-rings (if needed)

2. Turn Off the Water Supply

Locate the shut-off valves under the sink and turn off both the hot and cold water supply. This prevents any water from flowing into the faucet while you work.

3. Remove the Faucet Handles

Use an Allen wrench to loosen and remove the screws securing the handles. Gently pull the handles straight up to detach them from the faucet.

4. Remove the Stem Assemblies

Place an adjustable wrench on the packing nut located directly below the handle. Turn the packing nut counterclockwise to loosen it. Pull the stem assembly straight up to remove it.

5. Inspect the Washers or O-rings

Examine the washers or O-rings on the stem assembly. If they are worn, cracked, or damaged, replace them with new ones.

6. Apply Plumber's Putty

Apply a thin layer of plumber's putty to the base of the stem assembly where it will make contact with the faucet body.

7. Reinstall the Stem Assemblies

Carefully insert the stem assemblies back into the faucet body. Hand-tighten the packing nuts to secure them.

8. Tighten the Packing Nuts

Using the adjustable wrench, gently tighten the packing nuts further. Be careful not to overtighten, as this can damage the faucet.

9. Reattach the Handles

Align the handles correctly and insert them back onto the stems. Secure them with the screws using the Allen wrench.

10. Turn on the Water Supply

Turn on the shut-off valves under the sink to restore the water supply. Check for any leaks at the handles or base of the faucet.

11. Adjust the Handles

Adjust the handles until they move smoothly and the water flows evenly from both the hot and cold sides.

Tips for Prevention and Maintenance

To prevent future leaks and maintain the health of your faucet, consider the following tips:

- Regularly clean the faucet and its components to remove mineral buildup. - Monitor the condition of the washers or O-rings and replace them as needed. - If the faucet is subject to frequent use, consider installing a water hammer arrestor to reduce pressure surges. - Call a professional plumber if the leak persists or if you encounter any unexpected difficulties.
