• A screwdriver
• A wrench
• A basin wrench
• Penetrating oil

1. Turn off the water supply to the faucet. This is usually located under the sink.

Repair the Faucet

Once you have disassembled the faucet, you can begin to repair it. The following are some common repairs for single-handle faucets:

• Replace the O-rings. O-rings are small rubber rings that seal the faucet. If the O-rings are worn or damaged, they can cause leaks. To replace the O-rings, you will need to remove the faucet cartridge. Once the cartridge is removed, you can replace the O-rings.
• Replace the cartridge. The cartridge is the heart of the faucet. It is responsible for controlling the flow of water and the temperature of the water. If the cartridge is damaged, it will need to be replaced. To replace the cartridge, you will need to remove the faucet handle and escutcheon. Once the handle and escutcheon are removed, you can access the cartridge. Remove the old cartridge and install the new one.
• Replace the faucet stem. The faucet stem is the part of the faucet that connects the handle to the cartridge. If the faucet stem is damaged, it will need to be replaced. To replace the faucet stem, you will need to remove the handle and escutcheon. Once the handle and escutcheon are removed, you can access the faucet stem. Remove the old faucet stem and install the new one.

Once you have repaired the faucet, you can reassemble it. Be sure to tighten all of the nuts and screws securely. Turn on the water supply to the faucet and test it to make sure that it is working properly.

Reparing a single-handle faucet is a relatively simple task. By following these steps, you can save yourself the time and money of hiring a plumber. However, if you are not comfortable working with plumbing fixtures, it is best to consult with a professional.
