How To Repair a Leaking Kitchen Sink Faucet

Dealing with a leaking kitchen sink faucet can be a frustrating experience. Fortunately, it is a fairly easy fix that doesn’t require a professional plumber or a lot of expensive tools. With a few simple steps, you can repair your kitchen sink faucet and get back to your daily routine.


    • Wrench
    • Screwdriver
    • Replacement Cartridge
    • Plumber’s Tape


    • First, you’ll need to shut off the water supply to your kitchen sink. This can usually be done with a knob or handle under the sink.
    • Next, you’ll need to remove the handle. You can do this by loosening the large set screws with a screwdriver or wrench. Once the handle is disassembled, you’ll be able to access the cartridge.
    • At this point, you’ll need to remove the cartridge. You may need a wrench to loosen the nuts that hold the cartridge in place. Once you’ve removed the cartridge, make sure to inspect it for damage.
    • If the cartridge is damaged, you’ll need to replace it. Make sure to get a cartridge that is designed for your specific type of faucet. Before installing the new cartridge, use plumbers tape to seal the threads. This will ensure that the new cartridge does not leak.
    • Once the new cartridge is installed, you’ll need to reassemble the faucet. Start by putting the handle back on and then replacing the set screws. Finally, turn the water supply back on and check to make sure there are no leaks.


Repairing a leaking kitchen sink faucet is a simple DIY project that can be done in less than an hour. All you need is a few basic tools and a replacement cartridge and you’ll be able to fix the leak and get back to your daily routine. It is essential to maintain a functioning plumbing system in the home, and this includes dealing with problems such as a leaking kitchen sink faucet. While it may be tempting to ignore the drip-drip-drip as it slowly drains away your water and money, it is important to take care of the issue sooner rather than later. Unchecked, a leaking kitchen sink faucet can lead to costly water damage and potential mold infestation. Here are some tips on how to repair a leaking kitchen sink faucet:

1. Identify the problem. Is the leak coming from the faucet itself, the actual handle, or somewhere else? Take a closer look and locate the source of the leak for a more effective repair.

2. Turn off the water valve and move toward the faucet. You may need to access the faucet and its fixtures in order to begin the repair. These can usually be found underneath the sink, and they can be unscrewed to give better access to the problem area.

3. Disassemble the faucet. Depending on the type of faucet you have, this may involve removing one or more components such as a handle, a stem, a seal, and other parts. Make sure to keep track of each piece in case you need to put the faucet back together again.

4. Replace the seals. This can be done with a new seal or with a rubber gasket sealer. Whichever type you choose, make sure that the new seal fits tightly in order to prevent further water leakage.

5. Put everything back together. Reassemble the faucet and its components, and then turn the water valve back on. Finally, test the faucet to make sure that it is no longer leaking.

By following these steps, you should be able to repair a leaking kitchen sink faucet on your own or with the help of a plumber. If the issue persists, it may be worth looking into replacing the entire unit with a brand-new faucet.
