How to Repair a Leaking Moen Shower Faucet

Moen shower faucets are known for their durability and reliability, but even the best faucets can eventually start to leak. If you’re experiencing a leak from your Moen shower faucet, don’t despair. With a few simple tools and some basic plumbing skills, you can usually fix the problem yourself.

This guide will walk you through the process of repairing a leaking Moen shower faucet. We’ll start by identifying the source of the leak, then we’ll show you how to turn off the water supply and remove the faucet handle. Once the faucet is disassembled, we’ll walk you through the steps of repairing the leak and reinstalling the faucet.

Identify the Source of the Leak

The first step in repairing a leaking Moen shower faucet is to identify the source of the leak. This can be done by following the path of the water from the faucet to the point where it’s leaking.

In most cases, the leak will be coming from one of the following areas:

• The faucet handle
• The faucet cartridge
• The shower valve
• The shower arm

To identify the source of the leak, you’ll need to turn on the water to the faucet and look for any signs of water coming out of these areas. If you see water coming out of the faucet handle, the problem is likely with the faucet cartridge. If you see water coming out of the faucet body, the problem is likely with the shower valve. And if you see water coming out of the shower arm, the problem is likely with the shower arm itself.

Once you’ve identified the source of the leak, you can begin the next step of repairing the faucet.

Turn Off the Water Supply

Before you can begin repairing the leak, you’ll need to turn off the water supply to the faucet. This can be done by turning the shut-off valve located behind the faucet clockwise.

If you can’t find the shut-off valve, you may need to turn off the water to the entire house. This can be done by turning the main water shut-off valve located near the water meter.

Once you’ve turned off the water supply, you can begin removing the faucet handle.

Remove the Faucet Handle

To remove the faucet handle, you’ll need to use a flat-head screwdriver to pry off the decorative cap that covers the screw underneath. Once the cap is removed, you can use the screwdriver to loosen the screw and remove the handle.

On some Moen shower faucets, the handle is held in place by a clip. To remove this type of handle, you’ll need to use a pair of needle-nose pliers to pry up the clip and release the handle.

Once the handle is removed, you can access the faucet cartridge.

Repair the Leaking Faucet Cartridge

The most common cause of a leaking Moen shower faucet is a worn-out faucet cartridge. To repair a leaking faucet cartridge, you’ll need to remove the old cartridge and replace it with a new one.

To remove the old cartridge, you’ll need to use a pair of pliers to grip the cartridge and turn it counterclockwise. Once the cartridge is loose, you can pull it out of the faucet body.

Before you install the new cartridge, make sure to apply a thin coat of plumber’s grease to the O-rings. This will help to create a watertight seal.

Once the new cartridge is installed, you can reinstall the faucet handle and turn on the water supply.

If the leak is still present, you may need to replace the shower valve or shower arm.

Replace the Shower Valve or Shower Arm

To replace the shower valve, you’ll need to turn off the water supply to the entire house and drain the water from the pipes. Once the pipes are drained, you can remove the old shower valve and install the new one.

To replace the shower arm, you’ll need to turn off the water supply to the faucet and remove the old shower arm. Once the old shower arm is removed, you can install the new one.

Once the new shower valve or shower arm is installed, you can turn on the water supply and test the faucet for leaks.
