How To Fix A Dripping Moen Bathroom Faucet?

A dripping Moen bathroom faucet can be a major annoyance, not to mention a waste of water. If you’re tired of listening to the drip, drip, drip, and you’re ready to save some money on your water bill, you’ve come to the right place. In this guide, we’ll show you how to identify and troubleshoot a dripping Moen bathroom faucet, so you can get it fixed quickly and easily.

Identifying the Problem

The first step to fixing a dripping Moen bathroom faucet is to identify the problem. Here are some of the signs that your faucet is dripping:

  • The faucet is constantly dripping, even when it’s turned off.
  • The faucet drips when you turn it on and off.
  • The faucet drips when you’re using it.
  • The faucet drips after you’ve turned it off for a while.

If you’re seeing any of these signs, your faucet is probably dripping. However, you’ll need to do a little more troubleshooting to figure out what’s causing the problem.

How to Tell if the Problem is with the Faucet or the Water Supply Line

The first thing you need to do is determine if the problem is with the faucet itself or the water supply line. To do this, you’ll need to turn off the water supply to the faucet.

To turn off the water supply to the faucet, follow these steps:

1. Find the shut-off valve for the faucet. The shut-off valve is usually located near the faucet, on the water supply line.
2. Turn the shut-off valve clockwise until it’s completely closed.

Once you’ve turned off the water supply to the faucet, check to see if the drip stops. If the drip stops, the problem is with the faucet. If the drip continues, the problem is with the water supply line.

Troubleshooting the Problem

If the problem is with the faucet, you’ll need to troubleshoot the problem to figure out what’s causing the drip. Here are some common causes of a dripping Moen bathroom faucet:

  • A worn-out washer. The washer is a small, rubber disk that sits between the faucet stem and the faucet body. Over time, the washer can wear out and become damaged. This can cause the faucet to drip.
  • A loose faucet stem. The faucet stem is the part of the faucet that controls the flow of water. If the faucet stem is loose, it can cause the faucet to drip.
  • A clogged cartridge. The cartridge is a small, plastic or metal cylinder that controls the flow of water through the faucet. If the cartridge becomes clogged, it can cause the faucet to drip.

To troubleshoot the problem, you’ll need to remove the faucet handle and stem. Once you’ve removed the handle and stem, you can inspect the faucet for damage or wear. If you find a worn-out washer, a loose faucet stem, or a clogged cartridge, you can replace the damaged part.

Replacing the Washer

To replace the washer, follow these steps:

1. Remove the faucet handle and stem.
2. Locate the washer. The washer is a small, rubber disk that sits between the faucet stem and the faucet body.
3. Remove the old washer. You can use a small screwdriver or a pair of pliers to remove the old washer.
4. Install the new washer. Make sure the new washer is the correct size.
5. Reinstall the faucet handle and stem.

Tightening the Faucet Stem

To tighten the faucet stem, follow these steps:

1. Remove the faucet handle and stem.
2. Locate the faucet stem. The faucet stem is the part of the faucet that controls the flow of water.
3. Use a wrench to tighten the faucet stem.
4. Reinstall the faucet handle and stem.

Replacing the Cartridge

To replace the cartridge, follow these steps:

1. Turn off the water supply to the faucet.
2. Remove the faucet handle and stem.
3. Locate the cartridge. The cartridge is a small, plastic or metal cylinder that controls the flow of water through the faucet.
4. Remove the old cartridge. You can use a small screwdriver or a pair of pliers to remove the old cartridge.

Over time, faucet washers can wear out and become damaged. This can cause the faucet to drip. To fix this problem, you will need to replace the faucet washer.

To replace a faucet washer, you will need the following tools:
