How to Fix a Dripping Bathroom Sink Faucet with a Single Handle
A dripping bathroom sink faucet is a common problem that can waste water and increase your energy bills. Fortunately, it is usually a relatively simple repair that you can do yourself with a few basic tools.
Here are the steps on how to fix a dripping bathroom sink faucet with a single handle:
1. Gather your tools
You will need the following tools:
- Adjustable wrench
- Phillips screwdriver
- Flathead screwdriver
- Replacement faucet cartridge
2. Turn off the water supply
The first step is to turn off the water supply to the faucet. There are usually two valves under the sink, one for hot water and one for cold water. Turn both valves clockwise to shut off the water.
3. Remove the faucet handle
Once the water is turned off, you can remove the faucet handle. On most single-handle faucets, the handle is held in place by a small screw. Use a Phillips screwdriver to remove the screw and then pull the handle straight up to remove it.
4. Remove the cartridge
Once the handle is removed, you will see the cartridge. The cartridge is a cylindrical-shaped component that controls the flow of water. To remove the cartridge, use a flathead screwdriver to pry it loose from the faucet body. Be careful not to damage the cartridge or the faucet body.
5. Install the new cartridge
Take the new cartridge and align it with the faucet body. Push the cartridge into place until it is firmly seated. Then, use the flathead screwdriver to tighten the cartridge in place.
6. Reinstall the handle
Once the cartridge is installed, you can reinstall the handle. Push the handle onto the faucet body and then secure it with the screw.
7. Turn on the water supply
Once the handle is installed, you can turn on the water supply to the faucet. Check for leaks and make sure the faucet is working properly.
Tips
- If you are not comfortable replacing the cartridge yourself, you can call a plumber for assistance.
- If you have a two-handle faucet, the repair process is similar. The main difference is that you will need to replace both cartridges.
- It is a good idea to replace the faucet cartridge every few years to prevent leaks and ensure smooth operation.
