How to Fix a Dripping Kitchen Sink Faucet [Easy Step-by-Step Guide 2025]

If you’re like me, the sound of a dripping kitchen faucet can drive you crazy. That constant drip, drip, drip is not only irritating, but it can also waste a surprising amount of water (and money) over time. Luckily, fixing a leaky faucet is usually a relatively simple DIY project that doesn’t require calling in a plumber.

In this comprehensive guide, I’ll walk you through the most common causes of a dripping faucet and show you how to fix it step-by-step. By the end, you’ll have your kitchen sink running good as new—and you might even impress your friends and family with your plumbing prowess!

Why is My Kitchen Faucet Dripping?

Before we jump into the fix, let’s first take a look at what’s actually causing that annoying drip. There are a few main culprits behind a leaky kitchen faucet:

• Worn-out washers or O-rings: The washers and O-rings inside your faucet can become worn down over time, allowing water to seep through.
• Damaged faucet cartridge: Many modern faucets use a cartridge system rather than separate washers. If the cartridge is cracked or damaged, it will need to be replaced.
• Mineral buildup: Hard water can cause mineral deposits to accumulate inside the faucet, affecting the seal and causing leaks.
• Loose faucet handle: If the faucet handle is loose, it can create gaps that allow water to escape.

In some cases, the issue may be more serious, like a problem with the faucet’s internal mechanisms or even the plumbing behind the wall. But in most situations, a dripping kitchen faucet is an easy fix that you can handle yourself.

How to Fix a Leaky Kitchen Faucet: Step-by-Step Guide

Okay, let’s get to the good stuff—how to actually stop that leak! Here’s a step-by-step process for fixing a dripping kitchen sink faucet:

1. Turn Off the Water Supply

The first and most crucial step is to shut off the water supply to the faucet. There are usually two shut-off valves located underneath the sink—one for hot water and one for cold. Turn both of these valves clockwise to the closed position.

If you don’t have shut-off valves (or they’re not working), you may need to turn off the main water supply to your entire house. This is a bit more involved, but it’s better than having water spraying everywhere while you work on the faucet.

2. Remove the Faucet Handle

Next, you’ll need to remove the faucet handle. This is usually done by loosening a set screw or prying off a cap to expose the handle’s attachment point. Consult your faucet’s instruction manual if you’re unsure of the process.

Once the handle is off, you should be able to see the faucet stem—the main mechanism that controls water flow. This is where we’ll focus our attention.

3. Disassemble the Faucet Stem

Depending on your faucet type, the stem may come out as a single unit or it may have multiple pieces. Carefully remove the stem and inspect it for any worn or damaged components.

Look for things like:

• Worn washers or O-rings
• A cracked or bent stem
• Mineral buildup

If you find any of these issues, you’ll need to replace the damaged parts. Make note of the specific components you need so you can purchase the right replacement pieces.

4. Clean and Reassemble the Faucet

Once you’ve identified the problem, it’s time to clean and reassemble the faucet. Start by thoroughly cleaning all the faucet components to remove any mineral deposits or grime.

Then, carefully put the faucet stem back together, making sure all the pieces are aligned properly. Replace any worn washers, O-rings, or other damaged parts with the new ones you purchased.

Finally, reattach the faucet handle and turn the water supply back on. Check for any remaining leaks and make any necessary adjustments.

5. Test the Repaired Faucet

With the water back on, turn the faucet handle and check for any drips or leaks. If everything looks good, congratulations—you’ve successfully fixed your leaky kitchen sink faucet!

If you’re still experiencing issues, you may need to dig a bit deeper. Try removing the entire faucet assembly and inspecting it more closely. You may also need to replace the entire faucet cartridge or stem if the damage is too extensive.

Conclusion

Fixing a dripping kitchen faucet may seem daunting, but with the right tools and a bit of patience, it’s a job most homeowners can handle. By following the steps outlined in this guide, you’ll be able to diagnose the problem, replace any worn parts, and get your faucet working like new again.

Not only will this save you money on plumber fees, but it’s also a great feeling of accomplishment to tackle a home repair project yourself. Plus, you can impress your friends and family with your newfound plumbing skills!

So don’t let that constant drip drive you crazy any longer. Grab your toolkit and get to work—your kitchen sink will be good as new in no time.

FAQs

How often should I replace the washers and O-rings in my faucet?

As a general rule, it’s a good idea to replace the washers and O-rings in your faucet every 1-2 years, or anytime you notice signs of wear and tear like cracks or deterioration. This will help prevent future leaks and keep your faucet working smoothly.

Can I fix a leaky faucet without turning off the water supply?

While it is possible to make minor faucet repairs without shutting off the water, it’s generally not recommended. Working on a faucet with the water still running can be messy and unsafe. It’s best to turn off the water supply first to avoid potential water damage or injury.

What tools do I need to fix a leaky faucet?

The basic tools required for faucet repair include pliers, basin wrench, hex wrenches, screwdrivers, and replacement washers/O-rings/cartridges. You may also need a bucket to catch any water and a rag to wipe up drips. Having the right tools on hand will make the job much easier.

How long will it take to fix a dripping faucet?

The time it takes to fix a leaky faucet can vary depending on the complexity of the issue and your DIY experience. A simple washer replacement may only take 15-30 minutes, while a more involved cartridge replacement could take an hour or more. Plan to set aside at least an hour for the project to be safe.

Should I call a plumber instead of fixing it myself?

In most cases, a dripping kitchen faucet is an easy DIY repair that doesn’t require calling in a professional plumber. However, if you’re uncomfortable working on plumbing fixtures or the issue seems more complex, it may be worth getting a plumber involved to ensure the job is done right. They have the expertise and tools to tackle even the trickiest faucet problems.
