Identifying the Source of the Leak

Before you start repairing the leak, it’s crucial to identify its source. Common causes of leaks in single-handle faucets include:

• Worn or damaged O-rings
• Loose handle
• Faulty cartridge
• Cracked faucet body

Tools and Materials You’ll Need

To fix a leaky kitchen faucet single handle, you’ll need the following tools and materials:

• Adjustable wrench
• Phillips head screwdriver
• Flat head screwdriver
• Allen wrench (if necessary)
• New O-rings (if necessary)
• Replacement cartridge (if necessary)
• Plumber’s putty
• Rags

Step-by-Step Repair Instructions

1. Turn Off the Water Supply

Before starting any repairs, turn off the water supply to the faucet. Locate the water valves under the sink and turn them clockwise to shut off the water.

2. Remove the Handle

Using a Phillips head screwdriver, remove the screw that secures the handle to the faucet body. Gently pull the handle straight up to remove it.

3. Inspect the O-Rings

Once the handle is removed, inspect the O-rings located under it. If the O-rings are worn, damaged, or missing, they need to be replaced.

4. Replace the O-Rings (Optional)

If the O-rings need replacing, apply a small amount of plumber’s putty to the new O-rings and place them in the grooves under the handle. Make sure the O-rings are properly seated.

5. Tighten the Handle

Reinstall the handle by aligning it with the O-rings and pushing it down firmly. Use the Phillips head screwdriver to tighten the screw that secures the handle.

6. Remove the Cartridge

Using an adjustable wrench, loosen the nut that holds the cartridge in place. Carefully pull the cartridge straight up to remove it.

7. Replace the Cartridge (Optional)

If the cartridge is faulty, it needs to be replaced. Insert the new cartridge into the faucet body and tighten the nut using the adjustable wrench.

8. Reassemble the Faucet

Once the cartridge is replaced, reassemble the faucet by pushing the handle down and tightening the screw. Turn on the water supply and check for leaks.

Troubleshooting

If the leak persists after following the above steps, try the following troubleshooting tips:

• Check the faucet body for cracks or damage. If the faucet body is cracked, it may need to be replaced.
• Inspect the connections between the faucet and the plumbing pipes. Make sure the connections are tight and there are no leaks.
• Consider replacing the entire faucet if the leak cannot be fixed with the above methods.
