How To Repair Moen Bathroom Faucet Dripping Water

A dripping bathroom faucet can be frustrating and wasteful. If you have a Moen bathroom faucet that is dripping, there are a few things you can do to repair it yourself.

Before you start, you'll need to gather a few tools. You'll need a Phillips head screwdriver, a flathead screwdriver, and a pair of pliers. You may also need a new washer or O-ring, depending on the cause of the leak.

Once you have your tools, follow these steps to repair your Moen bathroom faucet:

Turn off the water supply to the faucet. There should be two shut-off valves under the sink, one for the hot water and one for the cold water. Turn both valves clockwise to turn off the water.
Remove the aerator. The aerator is the small, screen-like attachment at the end of the faucet. Use a wrench or pliers to unscrew the aerator.
Inspect the washer or O-ring. The washer or O-ring is a small, rubber seal that sits inside the faucet. If the washer or O-ring is worn or damaged, it can cause the faucet to leak.
Replace the washer or O-ring. If the washer or O-ring is worn or damaged, you will need to replace it. You can purchase a new washer or O-ring at a hardware store.
Reinstall the aerator. Once you have replaced the washer or O-ring, you can reinstall the aerator. Screw the aerator back onto the faucet.
Turn on the water supply to the faucet. Turn the shut-off valves counterclockwise to turn on the water.

If your Moen bathroom faucet is still dripping after following these steps, you may need to call a plumber.
