How to Fix a Leaky Faucet – Simply Explained

A leaky faucet is not only annoying but can also lead to higher water bills and A dripping faucet might not seem like a big deal, but over time it can waste a surprising amount of water and lead to higher utility bills or even water damage. The good news? Fixing it yourself is easier than you might think. With a few basic tools and a bit of patience, you can stop the leak and feel great about saving both water and money. Here’s a straightforward, no-jargon guide to help you fix a leaky faucet at home.

Step 1: What You’ll Need

Before you start, gather these tools and materials:

Adjustable wrench
Screwdrivers (both flat-head and Phillips)
Replacement parts (like O-rings, washers, or a new cartridge depending on the faucet)
Plumber’s grease
A rag or cloth
A small bowl to keep tiny parts from rolling away

Step 2: Shut Off the Water

Look under your sink for the water shutoff valves and turn them clockwise to close. If you don’t see individual valves, you may need to shut off the main water supply to your home. Once off, turn on the faucet to release any remaining water in the line.

Step 3: Take the Faucet Apart

This part varies a bit depending on whether you have a compression, ball, cartridge, or ceramic disk faucet—but the basic idea is the same:

Remove the handle. You may need to pry off a decorative cap to reach the screw underneath.
Lift off the handle. If it’s stuck, a gentle wiggle or firm pull should do the trick.
Disassemble the body. Use your wrench to remove any retaining nuts or collars. As you go, keep track of each piece and how it fits back together.

Step 4: Find and Replace What’s Broken

Inspect the internal parts. The most common causes of leaks are worn-out washers, O-rings, or cartridges.

If you see damaged washers or O-rings, remove and replace them with new ones. A light coating of plumber’s grease helps seal and protect them.
If it’s a cartridge faucet, swap out the old cartridge for a new one that matches exactly. Bring the old part with you to the hardware store if you’re unsure.

Step 5: Put Everything Back Together

Time to reassemble:

Put all the internal components back in the reverse order you removed them.
Reattach the handle securely.
Turn the water supply back on slowly.

Then, test the faucet by turning it on and off a few times. The leak should be gone—and if it’s not, double-check that everything is seated correctly and tightened just enough (but not overtightened).

Fixing a leaky faucet is one of those small home repairs that feels great to complete on your own.
