Single Handle Bathroom Faucet Repair

A single handle bathroom faucet is a convenient and popular type of faucet that combines both hot and cold water into a single lever. When this type of faucet starts to leak or malfunction, it can be frustrating and lead to wasted water. Fortunately, repairing a single handle bathroom faucet is relatively easy and can be done with a few simple tools. ### Materials Needed * Adjustable wrench * Screwdriver (Phillips and flathead) * Replacement cartridge (if necessary) * Plumber's putty (optional) * Lubricating grease (optional) ### Step-by-Step Instructions

1. Turn off the water supply

Before starting any work on the faucet, turn off the water supply to the bathroom. There are typically two shut-off valves located under the sink. Turn the valves clockwise to close them.

2. Remove the aerator

The aerator is the small screen located at the tip of the faucet. Use a wrench to unscrew the aerator and remove it.

3. Unscrew the handle

Once the aerator is removed, you should see a small screw located beneath it. Use a screwdriver to remove the screw and then pull the handle straight up to detach it.

4. Remove the cartridge

The cartridge is the part of the faucet that controls the flow of water. Use an adjustable wrench to loosen the nut that holds the cartridge in place. Once the nut is loose, you can pull the cartridge straight out of the faucet body.

5. Inspect the cartridge

Inspect the cartridge for any damage or wear. If the cartridge is damaged, it will need to be replaced. If the cartridge is in good condition, it may simply need to be lubricated.

6. Lubricate the cartridge (optional)

If the cartridge is not damaged, you can lubricate it with a small amount of plumber's grease. Apply the grease to the O-rings and other moving parts of the cartridge.

7. Replace the cartridge (if necessary)

If the cartridge is damaged, replace it with a new one. Insert the new cartridge into the faucet body and tighten the nut to secure it in place.

8. Reinstall the handle

Place the handle back onto the faucet body and secure it with the screw.

9. Reinstall the aerator

Screw the aerator back onto the end of the faucet.

10. Turn on the water supply

Turn the shut-off valves under the sink counterclockwise to turn the water supply back on. Check for any leaks around the faucet.

Tips

* If you are not comfortable repairing the faucet yourself, call a licensed plumber. * Replace the aerator regularly to prevent mineral buildup. * Regularly lubricate the cartridge to keep the faucet working smoothly. * If the faucet is leaking from the base, it may need to be reseated with plumber's putty. By following these instructions, you can easily repair a single handle bathroom faucet and get it back in working order.
