How To Repair A Dripping Moen Bathroom Faucet

A dripping bathroom faucet is a common problem that can waste water and increase your water bill. If you have a Moen bathroom faucet that is dripping, there are a few things you can do to try and fix it yourself. Here are the steps on how to repair a dripping Moen bathroom faucet:

1. Gather your tools and materials

You will need the following tools and materials to repair a dripping Moen bathroom faucet:

Phillips head screwdriver
Flat head screwdriver
Allen wrench
Replacement cartridge (if necessary)
O-rings (if necessary)
Plumber's putty
Rags

2. Turn off the water supply

Before you start working on the faucet, you need to turn off the water supply. There are usually 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 supply.

3. Remove the aerator

The aerator is the small screen at the end of the faucet spout. It helps to aerate the water and create a more even flow. To remove the aerator, simply unscrew it by hand. If the aerator is stuck, you can use a pair of pliers to gently loosen it.

4. Remove the handle

Once the aerator is removed, you can remove the handle. To do this, use a Phillips head screwdriver to remove the screw that is holding the handle in place. Once the screw is removed, you can pull the handle straight up to remove it.

5. Remove the cartridge

The cartridge is the part of the faucet that controls the flow of water. To remove the cartridge, use an Allen wrench to loosen the screw that is holding it in place. Once the screw is loosened, you can pull the cartridge straight up to remove it.

6. Inspect the cartridge and O-rings

Once the cartridge is removed, you can inspect it for any damage. If the cartridge is damaged, it will need to be replaced. You should also inspect the O-rings on the cartridge for any damage. If the O-rings are damaged, they will need to be replaced.

7. Replace the cartridge and O-rings (if necessary)

If the cartridge or O-rings are damaged, they will need to be replaced. To replace the cartridge, simply insert the new cartridge into the faucet body and tighten the screw to hold it in place. To replace the O-rings, simply remove the old O-rings and replace them with new O-rings.

8. Reassemble the faucet

Once the cartridge and O-rings have been replaced, you can reassemble the faucet. To do this, simply insert the cartridge into the faucet body and tighten the screw to hold it in place. Then, place the handle back on the faucet and tighten the screw to hold it in place. Finally, screw the aerator back onto the end of the faucet spout.

9. Turn on the water supply and test the faucet

Once the faucet is reassembled, you can turn on the water supply and test the faucet. If the faucet is still dripping, there may be another problem that needs to be addressed. You may need to call a plumber to help you diagnose and repair the problem.
