How to Fix a Leaking Single Handle Bathroom Sink Faucet

A leaking sink faucet can be a nuisance, wasting water and potentially causing damage to your bathroom. Fortunately, fixing a single handle bathroom sink faucet is a relatively simple task that most homeowners can handle with a few basic tools. Here's a step-by-step guide to help you fix your leaking faucet: ### Gather the Necessary Tools Before you start, gather the following tools: * Adjustable wrench or crescent wrench * Phillips head screwdriver * Flathead screwdriver * Replacement cartridge (if needed) * Rags or towels * Plumber's putty (optional) ### Step 1: Turn Off the Water Supply The first step is to turn off the water supply to the sink. There will be two shutoff valves under the sink, one for the hot water and one for the cold water. Turn both valves clockwise to shut off the water. ### Step 2: Remove the Faucet Handle Once the water is turned off, remove the faucet handle. This is usually done by unscrewing a small set screw located at the base of the handle with a Phillips head screwdriver. Once the set screw is removed, pull the handle straight up to remove it. ### Step 3: Remove the Cartridge With the handle removed, you will see a cartridge. This is the part of the faucet that controls the flow of water. To remove the cartridge, use a flathead screwdriver to insert into the slots in the cartridge and turn it counterclockwise. Once the cartridge is loose, pull it straight out. ### Step 4: Inspect the Cartridge Inspect the cartridge for any signs of damage or wear. If the cartridge is damaged, it will need to be replaced. ### Step 5: Install a New Cartridge (If Needed) If the cartridge is damaged, replace it with a new one. To install the new cartridge, insert it into the faucet body and turn it clockwise until it is snug. ### Step 6: Apply Plumber's Putty (Optional) If you are replacing the cartridge, you can apply a small amount of plumber's putty to the base of the cartridge before inserting it. This will help to create a watertight seal. ### Step 7: Reinstall the Handle Once the cartridge is installed, reinstall the handle by pushing it straight down onto the faucet body. Tighten the set screw at the base of the handle with a Phillips head screwdriver. ### Step 8: Turn on the Water Supply Turn on the water supply to the sink and check for leaks. If there are any leaks, tighten the connections on the cartridge and the handle until the leak stops. ### Conclusion Fixing a leaking single handle bathroom sink faucet is a simple task that most homeowners can handle with a few basic tools. By following these steps, you can save yourself the cost of calling a plumber and have your sink back in working order in no time.
