Look under the sink to locate the shutoff valves on the water supply lines for the faucet. Most shutoff valves have a small, football-shaped handle or a lever that rotates. Close the valve for the faucet tap you will be working on by turning the handle clockwise until it stops.
If your house does not have shutoff valves under the sink, turn off the water supply to the house at the main shutoff valve. Once the water is shut off, open the faucet fully to release any pressure in the water lines and let any water drain out.
If your shutoff valves have levers instead of knobs, rotate the levers until they are perpendicular to the water pipes or tubing (the direction of the water flow).
Pull straight up on the cap to remove it from the faucet body.
Loosen the cartridge retaining nut. Unscrew the nut all the way and remove it from the faucet body.
Note the orientation of the faucet cartridge. You must reinstall the new cartridge in exactly the same way.
Pull the cartridge straight up to remove it from the faucet body. If necessary, grab the shaft at the top of the cartridge with pliers to pull out the cartridge.
Bring the old cartridge with you to the hardware store or home center to find an exact replacement. New cartridges typically include new rubber O-rings for the cartridge. If desired, also pick up some plumber's grease for the O-rings. This makes it easier to insert the cartridge into the faucet body and is an especially good idea if the old cartridge was difficult to remove.
If you have plumber's grease, apply a small amount to the cartridge's O-rings, using your finger.
Insert the new cartridge into the faucet body in the same orientation as the original cartridge. Push the cartridge all the way into the housing.
Secure the cartridge with the retaining nut, tightening the nut carefully (do not over-tighten. Reinstall the faucet cap.
Turn on the shutoff valve for the water supply to the tap by opening it counterclockwise all the way. Test the faucet for proper operation.
