How to Repair a Leaky Faucet Cartridge

You can easily repair a leaky faucet.

Cartridge faucets control the flow of water through holes in the body or stem of the cartridge. The cartridge also consists of a rubber O-ring to keep water from leaking out of the faucet. When a faucet begins to leak, the problem is either with the rubber O-ring or the cartridge itself. Faucet cartridges are located underneath the faucet handles on a double-handle faucet. You can purchase a cartridge at a local home remodeling or plumbing supply center.

Things You'll Need

• Thin, flathead screwdriver
• Phillips screwdriver
• Pliers

Instructions

1. Shut off the water supply to the sink. Located underneath the sink on the back wall are two shutoff valves. One controls the hot water, and the other controls the cold water. Turn the valves clockwise to shut off the water. Turn both water handles to the "On" position to release water pressure in the lines.

2. Remove the faucet handle on a double-handle faucet by prying off the retaining screw cover cap. Remove the handle retaining screw, and lift or twist off the handle.

3. Loosen the locking nut that holds the cartridge in place. The locking nut is located at the base of the cartridge on a double-handle faucet. Lift out the cartridge with a pair of pliers. You may need to twist the cartridge as you are removing it.

4. Take the old cartridge with you to purchase a replacement. Not all cartridges are alike, and it is easy to purchase one that will not fit.

5. Insert the new cartridge into the faucet with the flat side facing forward. Replace the locking nut, and tighten it with the pliers. Put the handle back in place, insert and tighten the handle retaining screw and snap the cover cap back in place.

Tips & Warnings

• Do not forget to turn off the water before removing your cartridge. Failure to do so will result in water spewing all over you and your kitchen.
