Replace Single Handle Bathroom Faucet Cartridge

Replacing a single handle bathroom faucet cartridge is a relatively simple procedure that can be completed in a short amount of time. By following these essential aspects, you can ensure that the job is done correctly and that your faucet will be working properly again in no time. ### Safety Precautions Before you begin working on your faucet, it is important to take a few safety precautions. First, 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 is turned off, you can open the faucet to release any residual water. Next, remove the aerator from the end of the faucet. This can be done by using a wrench or pliers to loosen the aerator and then unscrewing it by hand. ### Removing the Cartridge Once the aerator is removed, you will need to remove the cartridge. To do this, use a wrench or pliers to loosen the packing nut that is located behind the handle. Once the packing nut is loose, you can pull the cartridge straight out of the faucet. ### Installing the New Cartridge Before installing the new cartridge, it is important to lubricate the O-rings. This will help to ensure a watertight seal. Once the O-rings are lubricated, you can insert the new cartridge into the faucet. Push the cartridge straight into the faucet until it is fully seated. ### Replacing the Packing Nut Once the cartridge is installed, you can replace the packing nut. To do this, simply tighten the packing nut until it is snug. Be careful not to over-tighten the packing nut, as this could damage the cartridge. ### Reattaching the Aerator Once the packing nut is tightened, you can reattach the aerator. To do this, simply screw the aerator back onto the end of the faucet. ### Turning on the Water Supply Once the aerator is reattached, you can turn on the water supply to the faucet. Check for any leaks around the cartridge or the packing nut. If there are any leaks, you can tighten the packing nut a little bit more.
