A leaky faucet is more than just an annoyance—it wastes water, increases utility bills, and can even cause hidden damage if left untreated. Many homeowners assume that fixing a faucet requires calling a plumber. However, with the right tools, a little patience, and some guidance, you can handle this common household repair yourself. In this detailed handyman guide, we’ll walk you step by step through how to fix a leaky faucet while also sharing DIY plumbing tips for homeowners.

By the end, you’ll not only have a faucet that no longer drips but also the confidence to handle other basic home plumbing maintenance tasks.

Why Fixing a Leaky Faucet Matters

A dripping faucet may look harmless, but the numbers tell a different story. According to the U.S. Environmental Protection Agency, one household’s faucet leaking one drop per second can waste over 3,000 gallons of water per year. This wasted water also increases your water bill unnecessarily.

Ignoring the problem can also make it worse. Over time, constant dripping can cause:

• Corrosion in the faucet parts.
• Stains and water damage around sinks.
• Mold or mildew growth if water pools under the sink.

That’s why learning how to fix a leaky faucet is not just about convenience—it’s about saving resources, preventing damage, and keeping your home in good shape.

Common Causes of a Leaky Faucet

Before you grab your tools, it’s helpful to understand why faucets leak. Here are the most common reasons:

1. Worn-out washers – The rubber washer inside the faucet compresses every time you turn the handle. Eventually, it wears out and causes dripping.
2. Loose or damaged O-ring – O-rings help keep faucet parts sealed. When they loosen or crack, leaks start.
3. Corroded valve seat – Over time, water minerals can corrode the valve seat, leading to leaks near the spout.
4. Improper installation – If the faucet was installed incorrectly or too tightly, it may cause premature leaks.
5. Cartridge problems – In modern faucets, a faulty cartridge often causes drips or irregular water flow.

Identifying the cause saves time and helps you use the right repair method.

Tools Every Homeowner Should Have Before Starting

Before fixing your faucet, make sure you have the right tools ready. Having a basic toolkit not only helps with this job but prepares you for other common household repairs DIY.

Here’s what you’ll need:

• Adjustable wrench
• Phillips and flathead screwdrivers
• Pliers
• Hex (Allen) wrench set
• Replacement washers, O-rings, or faucet cartridges
• Plumber’s tape
• Cleaning cloth
• Small container (to hold screws and parts)

Tip: Always keep spare washers and O-rings in your toolbox. They are cheap, easy to store, and can save you from multiple trips to the hardware store.

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

Now that you have your tools, let’s go through the repair process step by step.

Step 1: Turn Off the Water Supply

Locate the shutoff valves under the sink and turn them clockwise to stop the water. If you can’t find them, shut off your home’s main water line. Always check by turning on the faucet to make sure the water flow has stopped completely.

Step 2: Plug the Drain

Use a sink plug or a cloth to cover the drain. This prevents small screws or washers from falling into the drain during the repair.

Step 3: Disassemble the Faucet

• Remove the decorative cap from the handle.
• Use a screwdriver or Allen wrench to loosen the screw holding the handle.
• Pull the handle off to access the inner parts.

Step 4: Inspect the Washer and O-Ring

• Carefully remove the nut or cartridge using your wrench.
• Check the washer and O-ring for cracks, wear, or buildup.
• Replace them with new ones of the same size.

Step 5: Clean and Reassemble

• Clean the valve seat with a cloth to remove dirt or corrosion.
• Apply plumber’s tape to ensure a tight seal.
• Reassemble the faucet in reverse order.

Step 6: Test the Faucet

Turn the water supply back on and slowly open the faucet. Let the water run for a few seconds to ensure the leak is gone.

If it’s still dripping, the issue may be with the cartridge or valve seat. In that case, replacing the cartridge is the next step, or you may need a professional plumber if corrosion is severe.

DIY Plumbing Tips for Homeowners

Once you learn how to fix a faucet, you can tackle other small plumbing jobs confidently. Here are some DIY plumbing tips for homeowners:

• Check for leaks regularly under sinks and behind toilets. Early detection prevents costly damage.
• Don’t overtighten fittings—this can damage washers and threads.
• Use plumber’s tape on threaded connections to prevent leaks.
• Flush your water heater yearly to remove sediment buildup.
• Know your main water shutoff valve location for emergencies.

These basic steps make plumbing maintenance less stressful and keep your home safe.
