How To Replace A Pfister Bathroom Faucet Cartridge

Replacing a Pfister bathroom faucet cartridge is a relatively easy task that can be completed in about 30 minutes. By following these simple steps, you can save yourself the cost of hiring a plumber.

The first step is to gather the necessary tools. You will need a Phillips head screwdriver, an adjustable wrench or channel-lock pliers, and a new Pfister bathroom faucet cartridge.

Once you have gathered your tools, you need to turn off the water supply to the faucet. There are usually two shut-off valves under the sink, one for the hot water and one for the cold water. Turn both valves to the "off" position.

Once the water supply is turned off, you can remove the old cartridge. First, remove the handle by unscrewing the set screw with the Phillips head screwdriver. Once the handle is removed, you will see a cap covering the cartridge. Use the adjustable wrench or channel-lock pliers to remove the cap.

Once the cap is removed, you will see the cartridge. Use the adjustable wrench or channel-lock pliers to unscrew the cartridge and remove it from the faucet.

Now you can install the new cartridge. First, apply a small amount of silicone grease to the O-rings on the new cartridge. Then, screw the new cartridge into the faucet. Hand-tighten the cartridge as much as possible, then use the adjustable wrench or channel-lock pliers to tighten it further.

Once the cartridge is installed, you can reattach the cap. Use the adjustable wrench or channel-lock pliers to tighten the cap.

Finally, reattach the handle. Screw the set screw back into the handle and tighten it with the Phillips head screwdriver.

Now you have successfully replaced the Pfister bathroom faucet cartridge. Turn the water supply back on and test the faucet to make sure it is working properly.
