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

A leaky faucet is a common household issue that can be both annoying and costly if not addressed promptly. In this guide, we’ll cover how to fix a leaky faucet step-by-step, helping you save water and money. 

Whether you’re a DIY enthusiast or prefer professional help, understanding the basics of faucet repair can make a big difference.

Why Fixing a Leaky Faucet Matters

The Cost of Ignoring a Leak

Ignoring a leaky faucet can lead to higher water bills and potential water damage. A faucet that drips once per second can waste over 3,000 gallons of water a year! Fixing a leaky faucet promptly helps you conserve water and avoid unnecessary costs.

Tools and Materials You’ll Need

Essential Tools for the Job

Before you start, gather these tools:

  • Adjustable wrench
  • Phillips and flathead screwdrivers
  • Pliers
  • Replacement parts (washers, O-rings, etc.)
  • Plumber’s tape
  • Hex key or Allen wrench

Finding Replacement Parts

You can find replacement parts at local hardware stores, home improvement centers, or online retailers. Bringing the old part with you ensures you get the correct replacement.

Understanding the Types of Faucets

Identify Your Faucet Type

Knowing your faucet type is crucial for a successful repair. The main types include:

  • Compression faucets: Separate handles for hot and cold water.
  • Ball faucets: Single handle, often found in kitchens.
  • Cartridge faucets: Single or double handles, smooth handle movement.
  • Ceramic disk faucets: Single handle, long-lasting with a ceramic disk.

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

Step 1: Turn Off the Water Supply

Locate the shut-off valves under the sink and turn them off. If you can’t find them, turn off the main water supply.

This step prevents water from spraying everywhere when you disassemble the faucet.

Step 2: Disassemble the Faucet

Use a screwdriver to remove the handle. Depending on your faucet type, you may need a hex key or Allen wrench.

Carefully disassemble the faucet, laying out the parts in the order you remove them.

Step 3: Inspect and Replace Worn-Out Parts

Check the washers, O-rings, and other components for wear. Worn-out washers or O-rings are common causes of leaks.

Replace any damaged parts with new ones.

Step 4: Reassemble the Faucet

After replacing the worn-out parts, reassemble the faucet in the reverse order of disassembly.

Make sure everything is tightly secured but avoid over-tightening, which can cause damage.

Step 5: Turn the Water Supply Back On

Turn the shut-off valves back on and check the faucet. Run the water and observe if there are any leaks.

If the faucet still leaks, double-check that all parts are properly installed and tightened.

When to Consider Replacing the Faucet

Assessing the Situation

Sometimes, repairing the faucet isn’t enough. Consider replacing your faucet if:

  • The faucet is old and corroded.
  • Multiple parts need replacement.
  • The leak persists despite repairs.

Benefits of a New Faucet

A new faucet can enhance your sink’s functionality and aesthetic appeal.

Modern faucets are designed to be more efficient, potentially saving you water and money in the long run.

Preventing Future Leaks

Regular Maintenance Tips

Prevent future leaks with regular maintenance:

  • Clean aerators periodically to prevent mineral buildup.
  • Check for loose parts and tighten them as needed.
  • Avoid using excessive force when operating the faucet.
