Moen Medina Kitchen Faucet Leaking at Base: How to Fix It

If you have a Moen Medina kitchen faucet and you’re experiencing leaks at the base, you’re not alone. This is a common problem that can be caused by a variety of issues. In this article, we’ll walk you through the steps to identify and fix the problem so you can enjoy a leak-free faucet once again.

Step 1: Turn off the Water Supply

The first step in fixing a leaking Moen Medina kitchen faucet is to turn off the water supply. Look for the shut-off valves under the sink and turn them clockwise until the water stops flowing. If you can’t find the shut-off valves, you may need to turn off the main water supply to your house.

Step 2: Remove the Handle

Once the water supply is turned off, you can start disassembling the faucet. Begin by removing the handle. This can usually be done by loosening a set screw with an Allen wrench or a screwdriver.

Step 3: Remove the Cartridge

Next, you’ll need to remove the cartridge. This is the part of the faucet that controls the water flow. To remove the cartridge, you may need to use pliers or a cartridge removal tool. Follow the manufacturer’s instructions for your specific model.

Step 4: Inspect the Cartridge

With the cartridge removed, inspect it for any signs of damage or wear. If the cartridge is cracked or broken, it will need to be replaced. If it appears to be in good condition, clean it thoroughly with a soft brush and vinegar or a commercial cleaner.

Step 5: Inspect the O-Ring

The O-ring is a small rubber ring that seals the cartridge in place. Inspect it for any signs of wear or damage. If it’s worn or damaged, it will need to be replaced.

Step 6: Inspect the Valve Seat

The valve seat is the part of the faucet body that the cartridge sits on. Inspect it for any signs of damage or wear. If it’s damaged, you’ll need to replace it.

Step 7: Replace the Cartridge

If the cartridge is in good condition, or you’ve replaced it, it’s time to reassemble the faucet. Insert the cartridge back into the faucet body and tighten it with pliers or a cartridge removal tool.

Step 8: Replace the O-Ring

If you’ve replaced the O-ring, slide it into place over the cartridge. Make sure it’s seated properly and is in good condition.

Step 9: Replace the Valve Seat

If you’ve replaced the valve seat, install the new one according to the manufacturer’s instructions. Make sure it’s snug and secure.

Step 10: Reinstall the Handle

With everything back in place, it’s time to reinstall the handle. Tighten the set screw with an Allen wrench or a screwdriver.

Step 11: Turn on the Water Supply

Once the handle is back in place, turn on the water supply. Check for leaks around the base of the faucet. If you don’t see any leaks, turn on the faucet and make sure it’s working properly.

Step 12: Tighten Loose Connections

If you’re still experiencing leaks at the base of the faucet, it’s possible that there’s a loose connection. Check all the connections between the faucet and the sink and tighten any that are loose.

Step 13: Check for Cracks in the Faucet Body

If tightening the connections doesn’t solve the problem, check the faucet body for cracks or damage. If you find any, you’ll need to replace the entire faucet.

Step 14: Check the Supply Lines

If you’re still experiencing leaks, it’s possible that there’s a problem with the supply lines. Check them for any signs of damage or wear. If they’re damaged, they’ll need to be replaced.

Step 15: Check the Sink

If none of the previous steps have solved the problem, it’s possible that the sink itself is damaged. Check for cracks or damage around the base of the faucet. If you find any, you’ll need to repair or replace the sink.

Step 16: Contact Moen Customer Service
