3. Turn off the water supply to the faucet.

The first step is to turn off the water supply to the faucet. This can be done by turning the shut-off valves located under the sink. Once the water supply is turned off, you can begin removing the handle(s) from the faucet.

4. Remove the handle(s) from the faucet.

To remove the handle(s) from the faucet, you will need to first remove the screws that hold them in place. These screws are typically located on the back of the handle(s). Once the screws are removed, you can carefully pry the handle(s) off of the faucet.

Note: If the handles are stuck, you can try using a hair dryer to heat them up. This will make them easier to remove.

5. Remove the old cartridge.

Once the handle(s) are removed, you can access the old cartridge. The cartridge is located inside the faucet body. To remove the cartridge, you will need to first remove the retaining clip. This clip is typically located on the side of the cartridge. Once the retaining clip is removed, you can carefully pull the cartridge out of the faucet body.

Note: The cartridge may be stuck, so you may need to use a small screwdriver to pry it out.

6. Install the new cartridge.

To install the new cartridge, you will need to first apply a thin layer of plumber’s grease to the O-rings on the cartridge. This will help to create a watertight seal. Once the O-rings are greased, you can carefully insert the cartridge into the faucet body. Once the cartridge is inserted, you can replace the retaining clip.

7. Turn on the water supply to the faucet.

Once the new cartridge is installed, you can turn on the water supply to the faucet. The water should flow smoothly from the faucet without any leaks.

What if the new cartridge leaks?

If the new cartridge leaks, it may be because the O-rings are not properly seated. Try removing the cartridge and reseating the O-rings. You can also try using a different type of O-ring. If the leak persists, you may need to replace the cartridge.
