How to Fix a Dripping Faucet and Stop That Annoying Leak for Good

That steady drip coming from your faucet is more than just irritating. Over time, even a slow leak can waste hundreds of gallons of water and quietly add up on your water bill. The good news is that many faucet problems can be solved with a few basic tools and a little patience.

This guide walks you through how to fix a leaky faucet step by step, so you can stop that drip before it turns into something bigger.

Why Is Your Faucet Dripping in the First Place?

Before you reach for a wrench, it helps to understand what is causing water to leak in the first place. A dripping faucet usually comes down to worn-out internal parts. The most common culprits include a damaged washer, a cracked o-ring, a worn valve seat, or a faulty cartridge.

Hard water is another factor that many homeowners overlook. Mineral deposits and buildup from hard water can corrode internal parts over time, causing water to leak even in faucets that are relatively new. Corrosion, wear, and tear will eventually affect every faucet, no matter the brand or material.

High water pressure can also cause leaks, especially if the faucet drips only at certain times of day. When pressure builds beyond what the faucet is designed to handle, it forces water through even small gaps in the seal.

What You Will Need Before You Start

Gathering your tools ahead of time makes the job go much smoother. Here is what to have on hand:

• A flathead and Phillips screwdriver

• An adjustable wrench

• Replacement parts such as a washer, o-ring, or cartridge

• Plumber's grease

• A small container to catch water

  
  

Replacement parts are available at most hardware stores. If you are unsure what you need, take a photo of the faucet model before you head out.

Easy Steps to Fix Your Faucet

Step 1: Turn Off the Water

This is the most important step. Shut off the water supply using the valves located beneath the sink. Turn the faucet on briefly afterward to release any remaining pressure and clear the water from the line. Once the water is off, place a towel in the sink to catch drips and protect the drain.

Step 2: Remove the Handle

Look for a decorative cap on the top of the handle. Use a flathead screwdriver to pry it off gently. Beneath it, you will find a screw holding the faucet handle in place. Unscrew it and carefully remove the handle to expose the internal components.

Step 3: Access the Stem and Internal Parts

With the faucet handle removed, you will see a packing nut securing the valve stem in place. Use your wrench to loosen the packing nut and pull out the stem. This is where most of the damage tends to happen.

Inspect the small rubber washer at the bottom of the stem. This washer creates a watertight seal against the valve seat, and when it wears out, it starts causing water to leak. A worn rubber ring or o-ring along the side of the stem is another common source of a drip.

Step 4: Replace the Faulty Parts

If the washer or o-ring looks cracked, flattened, or corroded, it needs to be replaced. A simple repair like swapping out a small rubber washer or o-ring can stop a leak that has been dripping for months. Check the valve seat as well, since corrosion on the seat can prevent a proper seal even after you replace the washer.

For compression faucets, replacing the washer is usually enough. For cartridge-style faucets, you may need to replace the entire cartridge. Specialty faucets may require parts that are brand-specific, so check your faucet model if you are unsure.

Do not overtighten the new parts when reassembling. Doing so can damage the fitting and create new problems.

Step 5: Reassemble and Test

Put everything back in reverse order: stem, packing nut, faucet handle, screw, and decorative cap. Once everything is snug, turn on the water supply and turn the faucet on slowly. Spend a moment checking for leaks around the base and handle before calling it done.

Steps to Prevent Future Faucet Problems

Regular maintenance is one of the best ways to prevent leaks from developing in the first place.

Flushing out mineral deposits, replacing worn parts early, and avoiding excess water pressure all help prevent damage to your home over time.

If you have hard water, consider installing a filtration system. This helps prevent buildup that can become corroded inside valves and faucets. You can also learn more about water-efficient options and EPA WaterSense low-flow fixtures.
