How to Repair a Moen Double Handle Bathroom Faucet

When a double-handle bathroom faucet leaks, drips, or otherwise malfunctions, it can be a source of frustration and inconvenience. However, with a few basic tools and a little bit of know-how, you can often repair the faucet yourself and save the cost of calling a plumber. Here's a step-by-step guide on how to fix a Moen double-handle bathroom faucet:

Tools and Materials You'll Need:

Adjustable wrench
Phillips and flathead screwdrivers
Replacement cartridge (if needed)
O-rings (if needed)
Plumber's tape
Cloths

Step 1: Turn Off the Water Supply

The first step is to turn off the water supply to the faucet. There should be two shut-off valves located under the sink, one for the hot water and one for the cold water. Turn both valves clockwise until they are fully closed.

Step 2: Remove the Handle Caps

Next, remove the handle caps. For most Moen faucets, the caps can be pried off with a screwdriver or a butter knife. Once the caps are removed, you will see a screw that holds the handle in place.

Step 3: Remove the Handles

Use the screwdriver to remove the screws and then lift the handles straight up to remove them.

Step 4: Remove the Cartridge

With the handles removed, you will see the cartridge. The cartridge is a cylindrical-shaped component that contains the seals and other parts that control the flow of water. To remove the cartridge, use the adjustable wrench to loosen the cartridge nut. Once the nut is loosened, you can pull the cartridge straight out.

Step 5: Inspect the Cartridge

Once the cartridge is removed, inspect it for any damage or wear. If the cartridge is damaged, it will need to be replaced. If the cartridge is in good condition, you can simply clean it by wiping it down with a cloth and applying a small amount of lubricant to the seals.

Step 6: Replace the Cartridge

If you need to replace the cartridge, insert the new cartridge into the faucet body. Hand-tighten the cartridge nut until it is snug.

Step 7: Replace the Handles

Replace the handles by aligning them with the splines on the cartridge and then pushing them down until they are fully seated.

Step 8: Replace the Handle Caps

Replace the handle caps by pressing them back into place.

Step 9: Turn On the Water Supply

Turn the water supply valves back on. Open the faucet and check for leaks. If there are no leaks, then your repair is complete.

Troubleshooting

If you are still having problems with your Moen double-handle bathroom faucet, there are a few things you can check:

Make sure that the cartridge is fully seated in the faucet body.
Check the O-rings for any damage or wear. If the O-rings are damaged, they will need to be replaced.
Apply plumber's tape to the threads of the cartridge nut and the handle screws to help prevent leaks.

If you have tried all of the above and you are still having problems with your faucet, then you may need to call a plumber for assistance.
