A dripping faucet might seem like a small annoyance, but over time it can waste hundreds of gallons of water and increase your utility bill. Even a slow drip can add up to significant water loss each year. The good news is that most leaky faucets can be fixed with a few basic tools and a little patience. Here’s a step-by-step guide to help you stop that drip and save both water and money.

Identify Your Faucet Type

Before you start, it’s important to know what kind of faucet you have. The repair process depends on the type:

• Compression faucets – have separate handles for hot and cold water and use rubber washers to control flow.
• Cartridge faucets – use a cartridge that moves up and down to regulate water.
• Ball faucets – common in older single-handle kitchen sinks, with a rotating ball mechanism.
• Ceramic disk faucets – modern single-handle faucets that use ceramic disks to control flow and temperature.

Knowing your faucet type will help you determine which parts may need replacement.

Turn Off the Water Supply

Always start by turning off the water. Look under the sink for the shutoff valves—one for hot and one for cold water—and turn them clockwise to close. If you can’t find them, shut off the main water supply to your home.

Once the water is off, open the faucet to release any remaining pressure. Place a towel or stopper in the sink to prevent small parts from falling down the drain.

Disassemble the Faucet

The exact steps vary by faucet type, but here’s a general approach:

1. Remove the handle. Look for a small screw, often hidden under a decorative cap. Use an Allen wrench or screwdriver to remove it.
2. Take off the handle and trim. This exposes the internal parts—cartridge, stem, or ball assembly.
3. Loosen the retaining nut. Use an adjustable wrench, but be careful not to scratch the finish.
4. Inspect the internal parts. Look for worn washers, O-rings, or seals. These are often the cause of leaks.

Take the worn parts to a hardware store or home improvement center to find exact replacements.

Replace the Worn Parts

• Compression faucets: Replace the rubber washer and O-ring on the valve stem.
• Cartridge faucets: Replace the cartridge with a new one designed for your faucet model.
• Ball faucets: Replace the rubber seats and springs inside the faucet body.
• Ceramic disk faucets: Replace the entire disk cartridge if it’s cracked or worn.

Before reassembling, apply a small amount of plumber’s grease to the O-rings and threads to ensure a smooth fit and prevent future leaks.

Reassemble and Test

Reassemble the faucet in the reverse order. Turn the water supply back on slowly and test the faucet. If the drip is gone, you’ve successfully fixed it! If it still leaks, double-check that all parts are seated correctly and that no debris is trapped inside.

Prevent Future Leaks

To keep your faucet in good shape:

• Avoid overtightening handles. It wears out washers and seals faster.
• Clean and descale regularly. Mineral buildup can damage internal parts.
• Check for small leaks early. Fixing them right away prevents bigger problems later.
• Use plumber’s grease when reassembling to extend the life of seals and O-rings.

If you live in an area with hard water, consider installing a water softener to reduce mineral buildup in your plumbing fixtures.

When to Call a Plumber

While most faucet leaks are easy to fix, some situations call for professional help—such as when:

• The faucet is built into the wall or a complex fixture.
• You can’t identify the source of the leak.
• The leak persists after replacing parts.
• You notice water damage under the sink.

A licensed plumber can quickly diagnose the issue and ensure your plumbing is safe and up to code.

A Simple Fix with Big Benefits

Repairing a leaky faucet usually takes less than an hour, but it can save you gallons of water and lower your utility bills. It’s a small DIY project that makes a big difference—for your wallet and the environment. Plus, there’s nothing quite as satisfying as turning off the water and hearing… silence.
