Moen Pull Out Kitchen Faucet Leaking at Base

A leaking kitchen faucet can be a frustrating problem to deal with, especially if you don’t know the cause of the leak. If you have a Moen pull out kitchen faucet that is leaking at the base, there are a few things you can do to fix the problem. In this article, we will provide you with step-by-step instructions on how to troubleshoot and repair your Moen pull out kitchen faucet.

Step 1: Turn Off the Water Supply

The first step to fix a Moen pull out kitchen faucet that is leaking at the base is to turn off the water supply. You can do this by turning off the water valves located under the sink. Once you have turned off the water supply, turn on the faucet to release any remaining water in the system.

Step 2: Remove the Handle

Once the water supply is turned off, you can begin to disassemble the faucet. The first step is to remove the handle. To do this, locate the set screw on the handle and use an Allen wrench to remove it. Once the set screw is removed, you can lift the handle off the faucet.

Step 3: Remove the Escutcheon Plate

After you have removed the handle, the next step is to remove the escutcheon plate. This plate covers the base of the faucet and is held in place by screws. Use a screwdriver to remove the screws and then lift the plate off the faucet.

Step 4: Inspect the O-ring

With the escutcheon plate removed, you can now inspect the O-ring. The O-ring is a small rubber ring that sits around the base of the faucet. If the O-ring is damaged, it can cause the faucet to leak at the base. Inspect the O-ring for any signs of wear or damage. If the O-ring is damaged, you will need to replace it.

Step 5: Replace the O-ring

If the O-ring is damaged, you will need to replace it. To do this, remove the old O-ring and replace it with a new one. Make sure to use the correct size O-ring for your faucet model. Once the new O-ring is in place, reassemble the faucet.

Step 6: Reassemble the Faucet

With the new O-ring in place, you can now reassemble the faucet. Start by replacing the escutcheon plate and securing it with screws. Then, place the handle back on the faucet and secure it with the set screw. Finally, turn on the water supply and test the faucet to make sure the leak has been fixed.

Step 7: Check the Cartridge

If the O-ring is not the cause of the leak, the next step is to check the cartridge. The cartridge is the part of the faucet that controls the flow of water. If the cartridge is damaged or worn, it can cause the faucet to leak at the base. To check the cartridge, you will need to disassemble the faucet further.

Step 8: Remove the Cartridge

To remove the cartridge, use pliers to grip the cartridge and pull it out of the faucet. If the cartridge is stuck, you may need to use a cartridge puller to remove it. Once the cartridge is removed, inspect it for any signs of wear or damage.

Step 9: Replace the Cartridge

If the cartridge is damaged or worn, you will need to replace it. Moen offers replacement cartridges for their faucets, and you can purchase them online or at your local hardware store. Once you have the replacement cartridge, insert it into the faucet and secure it in place with the retaining clip.

Step 10: Reassemble the Faucet

With the new cartridge in place, you can now reassemble the faucet. Start by replacing the escutcheon plate and securing it with screws. Then, place the handle back on the faucet and secure it with the set screw. Finally, turn on the water supply and test the faucet to make sure the leak has been fixed.

Step 11: Check the Supply Lines

If the O-ring and cartridge are not the cause of the leak, the next step is to check the supply lines. The supply lines are the hoses that connect the faucet to the water supply. If the supply lines are damaged or loose, they can cause the faucet to leak at the base.

Step 12: Tighten the Supply Lines

To check the supply lines, turn off the water supply and remove the escutcheon plate. Inspect the supply lines for any signs of wear or damage. If the supply lines are loose, use pliers to tighten them. If the supply lines are damaged, you will need to replace them.

Step 13: Replace the Supply Lines

If the supply lines are damaged, you will need to replace them. Moen offers replacement supply lines for their faucets, and you can purchase them online or at your local hardware store. Once you have the replacement supply lines, install them and tighten them with pliers.

Step 14: Reassemble the Faucet

With the new supply lines in place, you can now reassemble the faucet. Start by replacing the escutcheon plate and securing it with screws. Then, place the handle back on the faucet and secure it with the set screw. Finally, turn on the water supply and test the faucet to make sure the leak has been fixed.

Step 15: Check the Baseplate

If the leak persists, the next step is to check the baseplate. The baseplate is the part of the faucet that sits on the sink or countertop. If the baseplate is loose or damaged, it can cause the faucet to leak at the base.

Step 16: Tighten the Baseplate

To check the baseplate, remove the handle and escutcheon plate. Inspect the baseplate for any signs of wear or damage. If the baseplate is loose, use a wrench to tighten the mounting nuts. If the baseplate is damaged, you will need to replace it.

Step 17: Replace the Baseplate

If the baseplate is damaged, you will need to replace it. Moen offers replacement baseplates for their faucets, and you can purchase them online or at your local hardware store. Once you have the replacement baseplate, install it and tighten the mounting nuts.

Step 18: Reassemble the Faucet

With the new baseplate in place, you can now reassemble the faucet. Start by replacing the escutcheon plate and securing it with screws. Then, place the handle back on the faucet and secure it with the set screw. Finally, turn on the water supply and test the faucet to make sure the leak has been fixed.

Step 19: Call a Professional

If you have followed all of these steps and the faucet is still leaking at the base, it may be time to call a professional. A plumber can diagnose the problem and provide you with a solution that will fix the leak for good.
