Stop the Drip: How to Fix a Leaky Faucet in 6 Simple Steps

Few household issues are as persistent—and as deceptively expensive—as a dripping faucet. While it may seem like a minor annoyance, that steady leak can waste gallons of water and quietly drive up your utility bills. If you’ve been wondering how to fix a leaky faucet, the good news is that many repairs are easy enough to handle yourself. For homeowners who want to better understand other plumbing components around the home, it’s also worth knowing how things like pipe joints and water supply systems vary across fixtures.

Here’s what you’ll learn in this blog:

• Why even small faucet leaks matter more than you think
• A clear, step-by-step process to fix most faucet types
• The tools you need and common issues to expect
• When it’s smarter (and safer) to call in a pro

Why Fixing a Leaky Faucet Should Be a Priority

While it’s tempting to ignore the occasional drip, doing so can lead to larger problems over time. Whether you live in Cottage Grove, MN, and surrounding areas, or elsewhere, a leaky faucet is a red flag that something needs attention.

Here are the top reasons you shouldn’t wait:

• Water Waste: A slow-dripping faucet can waste over 3,000 gallons of water per year
• Higher Water Bills: Even moderate leaks can cause monthly spikes in utility costs
• Structural Damage: Persistent leaks can result in mold, warped cabinetry, or damaged drywall
• Plumbing Strain: Leaks may indicate pressure imbalances or failing internal components
• Peace of Mind: Eliminating the sound of constant dripping improves sleep and reduces stress

6 Simple Steps to Fix a Leaky Faucet

Not every faucet leak requires a plumber. If the issue is due to worn washers, seals, or a damaged cartridge, you can usually handle it with some basic tools and a little time.

1. Turn Off the Water Supply

Before doing anything else, shut off the water to prevent an unexpected mess.

• Locate the water shutoff valves under your sink
• Turn them clockwise to stop water flow
• Turn on the faucet to drain any leftover water in the line

Place a small towel or bowl under the sink to catch any drips when disconnecting parts.

2. Plug the Drain

It’s surprisingly easy to lose small parts during a faucet repair. Prevent parts from falling into the sink by plugging the drain.

• Use a sink stopper or tightly rolled towel
• This ensures no screws or washers disappear mid-repair

3. Remove the Faucet Handle

Now you’ll begin disassembling the faucet to access the internal components.

• Use a flathead screwdriver to remove the decorative cap
• Unscrew the handle and gently lift it off
• Place all parts in the order you removed them

Take a quick photo of the faucet before you start. It’ll help with reassembly later.

4. Identify Your Faucet Type

Different faucets have different internal mechanisms, so it’s important to know which kind you’re working with.

• Compression faucet: Two handles, uses rubber washers
• Cartridge faucet: One or two handles, contains a replaceable cartridge
• Ball faucet: Single handle, uses a ball joint with seals and springs
• Ceramic disk faucet: Durable with a ceramic disk controlling water flow

Each type has its own common wear points, as detailed in the next step.

5. Replace the Worn Component

This is typically the source of the leak.

• Compression: Replace rubber washer at the base of the valve stem
• Cartridge: Pull out the cartridge and insert a matching new one
• Ball: Replace springs and rubber seals inside the body
• Ceramic disk: Clean or replace worn seals or cracked disk

Use plumber’s grease when installing new parts to ensure smooth operation and a tight seal.

6. Reassemble and Test

Once all parts are replaced and properly seated:

• Reattach the handle and tighten the screws
• Turn the water supply back on slowly
• Check for any drips while the faucet is off and while water runs

If the leak continues, you may have missed a worn component or have damage deeper within the plumbing.

What Tools You’ll Need

Having the right tools makes the process smoother and less frustrating. Before starting, gather these items:

• Adjustable wrench: To remove nuts or fittings
• Flathead and Phillips screwdrivers: For handle and cartridge access
• Allen wrench: Commonly used for single-handle faucets
• Replacement parts: Washer, O-ring, cartridge, or seals based on faucet type
• Plumber’s grease: Helps maintain watertight seals
• Rags or towels: For water cleanup and protecting finishes

Some older homes in Cottage Grove, MN, and surrounding areas may also require rust remover or a small wire brush to handle mineral buildup.

Faucet Types Compared: Leak Causes and Fixes

Knowing your faucet style will help you figure out where the leak is and what part likely needs replacement.

Faucet Type	Leak Cause	Common Fix
Compression	Worn washer	Replace washer and possibly the valve seat
Cartridge	Cracked or loose cartridge	Remove and replace with exact model
Ball	Damaged springs or seals	Replace internal springs, cam, or rubber seats
Ceramic Disk	Mineral buildup or cracked seal/disk	Clean inlet ports, replace worn seals or disk

If your faucet model is no longer available in stores, a universal replacement kit may help, or it might be time for a full fixture upgrade.

When to Skip the DIY and Call a Pro

While many homeowners can handle a leaky faucet repair, there are a few scenarios where calling in a licensed plumber is a better choice.

The Leak Persists After Replacement

If you’ve changed washers, cartridges, or seals and the leak continues, there may be an issue deeper in the valve seat or supply line.

You See Corrosion or Rust

In homes with older plumbing, particularly in Cottage Grove, MN, and surrounding areas, signs of corrosion might suggest aging or degraded pipes. DIY repairs won’t fix long-term damage.

There’s Water Under the Sink

If the leak is coming from underneath your faucet or inside the cabinet, it may involve pipe connections or fittings, not just the faucet hardware.

You Don’t Have the Right Tools

If you’re missing a basin wrench, can’t identify the faucet model, or aren’t sure which replacement part to buy, a quick professional visit can prevent hours of guesswork.

You’re Replacing Multiple Fixtures

Sometimes it’s more cost-effective to upgrade several fixtures at once, especially during bathroom or kitchen renovations. Letting a professional handle it ensures everything is installed up to code.

How to Prevent Faucet Leaks in the Future

Once your faucet is leak-free, a few preventive habits can help you avoid future issues:

• Turn handles gently: Overtightening wears out washers and seals faster
• Clean aerators regularly: Unscrew the tip of the faucet and rinse out sediment
• Check under your sink monthly for early signs of moisture or mold
• Flush hot water lines annually to remove mineral deposits
• Know your water pressure: Excessively high pressure can damage plumbing components

If you’re unsure whether water pressure or hard water might be contributing to faucet wear, a licensed plumber can evaluate your system and recommend solutions.

Get Rid of That Drip for Good

A leaky faucet isn’t just a nuisance—it’s a small problem that can lead to big consequences if ignored. Whether it’s wasted water, rising bills, or hidden damage, tackling the issue early makes all the difference. With the right tools and a little know-how, most homeowners in Cottage Grove, MN, and surrounding areas can handle the fix themselves.
