Moen Bathroom Faucet Fix Leak: A Step-by-Step Guide

Moen bathroom faucets are known for their durability and reliability. However, even the best faucets can develop leaks over time. If you have a Moen bathroom faucet that is leaking, don't panic. Here is a step-by-step guide to help you fix the leak.

Step 1: Gather Your Tools and Materials

Before you begin, you will need to gather the following tools and materials:

Adjustable wrench
Phillips head screwdriver
Flat head screwdriver
Pliers
Replacement faucet cartridge
Teflon tape
Plumber's putty

Step 2: Turn Off the Water Supply

Once you have gathered your tools and materials, you need to turn off the water supply to the faucet. There will be two valves under the sink that control the hot and cold water supply. Turn both valves clockwise until they are completely closed.

Step 3: Remove the Faucet Handle

With the water supply turned off, you can now remove the faucet handle. Most Moen bathroom faucets have a small screw on the top of the handle. Use the Phillips head screwdriver to remove the screw.

Once the screw is removed, you can pull the handle straight off the faucet. If the handle is stuck, you may need to use the pliers to pry it off.

Step 4: Remove the Cartridge

With the handle removed, you can now see the cartridge. The cartridge is a cylindrical-shaped piece of metal that is responsible for controlling the flow of water. Use the adjustable wrench to loosen the retaining nut that holds the cartridge in place.

Once the retaining nut is loose, you can pull the cartridge straight out of the faucet.

Step 5: Replace the Cartridge

With the old cartridge removed, you can now install the new cartridge. Before you install the new cartridge, apply a small amount of plumber's putty to the base of the cartridge. This will help to create a seal and prevent leaks.

Once the plumber's putty is applied, insert the new cartridge into the faucet. Hand-tighten the retaining nut until it is snug.

Step 6: Reattach the Faucet Handle

With the cartridge replaced, you can now reattach the faucet handle. Align the handle with the stem of the cartridge and press it into place. Secure the handle with the screw that you removed earlier.

Step 7: Turn On the Water Supply

Once the faucet handle is reattached, you can turn on the water supply. Slowly open the valves under the sink until the water is flowing through the faucet.

Check for leaks around the faucet. If you see any leaks, tighten the retaining nut until the leak stops.

Step 8: Test the Faucet

Once you have tightened the retaining nut, you can test the faucet to make sure it is working properly. Turn on the faucet and let the water run for a few minutes.

Check for leaks around the faucet. If you see any leaks, tighten the retaining nut until the leak stops.

If the faucet is working properly, you can now enjoy your leak-free Moen bathroom faucet.
