Dealing with a dripping kitchen faucet can be incredibly annoying.

Things You'll Need

Before diving into faucet repair, gather the necessary supplies:

Having these supplies close at hand will make the repair process much smoother.

Shutting Off the Water Supply

Before tackling any faucet repair, it's crucial to shut off the water supply lines. This prevents water from spraying out while the faucet is disassembled. Here's how to do it:

  1. Locate the water supply valves, typically under the sink. They will be connected to the hot and cold water supply lines.
  2. Turn the hot and cold knobs on the faucet to the "off" position.
  3. Turn the water supply valves clockwise to shut off the water.
  4. Turn on the faucet to release any built-up pressure and ensure no water is still flowing.

With the water supply stopped, you can now start taking the faucet apart without making a huge mess.

Inspecting the Faucet

Before jumping into repairs, inspect the faucet closely to try diagnosing the problem. Start by thoroughly cleaning the faucet with vinegar to remove any mineral deposits that could be causing leaks between components. Check for signs of corrosion, worn parts, and damage. Internal parts like the cartridge, washers, O-rings, and valve seats are common culprits. Any visibly damaged parts should be replaced.

Also consider testing the water pressure. If the leak only occurs when pressure is high, simply reducing the pressure may fix the issue.

Removing the Faucet Handle

With the water off, the next step is removing the faucet handle so you can access the internal components. Refer to the manufacturer's instructions for your specific model. Typically, there will be a small set screw on the handle that needs to be loosened with a screwdriver before pulling the handle up and off the faucet body. Place the handle somewhere safe so you can reattach it later.

Removing the Cartridge

The cartridge is an internal part containing seals, washers, and valves that control water flow and mixing. A damaged cartridge can cause leaks. Use a specialty cartridge removal tool to extract the old cartridge. Inspect seals and washers for cracks or tears and replace any worn parts with new ones.

Cleaning Hard Water Deposits

If the leak appears to be coming from limescale buildup around components, you can try dissolving the deposits before replacing any parts. Mix equal parts white vinegar and warm water and pour the solution over the affected areas of the faucet. Allow it to sit for a few hours before scrubbing away buildup with an old toothbrush. Repeat as needed until the deposits are gone.

Checking/Replacing Washers and Seals

Worn-out washers are another common source of leaks. After removing the cartridge, check the condition of the faucet washers. Remove the retainer nut holding the washer/seal in place with adjustable pliers or a wrench. Replace any leaky washer with a new one of the same size. Repeat this process to replace all seals and O-rings as needed.

Reassembling the Faucet

Once any worn parts have been replaced, it's time to reassemble the faucet. First, wrap plumber's tape around the threads of any components you removed to prevent future leakage. Then replace the parts in reverse order, being careful not to overtighten anything. Tighten pieces by hand first, then use a wrench to give an additional quarter turn.

Turning Water Back On

With the faucet reassembled, slowly turn the hot and cold water supply valves back on and check for any drips or leaks as pressure builds. Once you've confirmed no leaks, turn the faucet handles on to check water temperature and flow. Your kitchen faucet should now be drip-free and working properly again!

When to Call a Plumber

In some cases, if you've tried the steps above and are still experiencing leaks, professional help may be needed. Repairs involving very complex faucet designs or requiring specialty tools are often best left to qualified plumbers. Continued dripping despite your efforts will also necessitate calling in an expert. Don't ignore persistent leaks, as they can lead to mold, damages, and costly water bills over time.

Dripping faucets may seem like a minor nuisance, but promptly addressing leaks is important to avoid water waste and potential damages. In many cases, fixing a leaky kitchen faucet yourself is a simple DIY project requiring just a few tools and replacement parts. With proper maintenance and attention, you can stop those annoying drips and restore your faucet to full working condition.
