How to Remove a Single Handle Moen Bathroom Faucet

When a bathroom faucet starts malfunctioning, the culprit is often the cartridge, which is responsible for controlling the flow and temperature of the water.

Replacing a Moen single-handle bathroom faucet cartridge is a relatively easy task that can be accomplished with a few simple tools. Follow these step-by-step instructions to remove the faucet and replace the cartridge:

1. Gather Your Tools

You will need the following tools to remove a Moen single-handle bathroom faucet:

Phillips head screwdriver
Adjustable wrench
Basin wrench (optional)
Replacement Moen cartridge

2. Turn Off the Water Supply

Before you begin, turn off the water supply to the faucet. There are typically two shut-off valves under the sink, one for hot water and one for cold water. Turn both valves clockwise to turn off the water.

3. Remove the Handle

Locate the set screw on the back of the handle. Use a Phillips head screwdriver to loosen the set screw.

Once the set screw is loose, you can remove the handle by pulling it straight up.

4. Remove the Cartridge Retainer Nut

Once the nut is loose, you can remove it by hand.

5. Remove the Cartridge

Grip the cartridge with your hand and pull it straight up to remove it from the faucet body.

6. Replace the Cartridge

Insert the new cartridge into the faucet body and push it down until it is seated.

Tighten the cartridge retainer nut by hand until it is snug. Then, use an adjustable wrench to tighten it further, but do not overtighten.

7. Reinstall the Handle

Align the handle with the cartridge stem and push it down until it is seated.

Tighten the set screw on the back of the handle with a Phillips head screwdriver.

8. Turn On the Water Supply

Turn on the water supply to the faucet and check for leaks. If there are any leaks, tighten the cartridge retainer nut further.
