A leaky faucet can be a major annoyance, wasting water and driving up your utility bills. If you have a Moen bathroom faucet that's leaking, don't despair. With a few simple tools and a little bit of time, you can fix it yourself.
In this article, we'll walk you through the essential steps on how to fix a leaky Moen bathroom faucet. We'll cover everything from identifying the source of the leak to replacing the necessary parts.
Identifying the Source of the Leak
The first step in fixing a leaky faucet is to identify the source of the leak. This can be done by visually inspecting the faucet and looking for any obvious signs of water damage. Common sources of leaks include the following:
- The washer
- The O-rings
- The cartridge
- The aerator
Replacing the Washer
If the leak is coming from the washer, you'll need to replace it. The washer is a small, rubber ring that sits between the faucet handle and the stem. Over time, the washer can wear out and cause the faucet to leak. To replace the washer, follow these steps:
- Turn off the water supply to the faucet.
- Remove the handle by unscrewing the set screw.
- Remove the stem by unscrewing the packing nut.
- Replace the washer with a new one.
- Reassemble the faucet in reverse order.
Replacing the O-Rings
If the leak is coming from the O-rings, you'll need to replace them. O-rings are small, rubber rings that seal the connections between different parts of the faucet. Over time, O-rings can wear out and cause the faucet to leak. To replace the O-rings, follow these steps:
- Turn off the water supply to the faucet.
- Remove the handle by unscrewing the set screw.
- Remove the stem by unscrewing the packing nut.
- Replace the O-rings with new ones.
- Reassemble the faucet in reverse order.
Replacing the Cartridge
If the leak is coming from the cartridge, you'll need to replace it. The cartridge is a self-contained unit that controls the flow of water through the faucet. Over time, the cartridge can wear out and cause the faucet to leak. To replace the cartridge, follow these steps:
- Turn off the water supply to the faucet.
- Remove the handle by unscrewing the set screw.
- Remove the cartridge by unscrewing the retaining nut.
- Replace the cartridge with a new one.
- Reassemble the faucet in reverse order.
Replacing the Aerator
If the leak is coming from the aerator, you'll need to replace it. The aerator is a small, screen-like device that attaches to the end of the faucet spout. Over time, the aerator can become clogged with mineral deposits and cause the faucet to leak. To replace the aerator, follow these steps:
- Unscrew the aerator from the faucet spout.
- Clean the aerator by soaking it in vinegar for a few hours.
- Reattach the aerator to the faucet spout.
