Fixing this common faucet issue doesn't have to be complicated. In many cases, DIY faucet replacement or repair is possible as long as you have the right guidance.

In this article, experts from Aerator.com teach you how to fix a dripping faucet in six simple steps.

Why is My Faucet Leaking?

According to the U.S. Environmental Protection Agency, leaks account for up to 10,000 gallons of water per household annually. When you address faucet leaks and issues promptly, you don't just conserve water but also save a significant amount on utility bills.

Understanding the causes of a leaky faucet can help you figure out where to start. Common reasons include worn-out washers, corroded valve seats, faulty seals and loose parts.

Different types of faucets (compression, ball, cartridge, and ceramic disk) can leak for various reasons. For example, compression faucets often suffer from worn washers, while ball faucets may leak due to worn-out seals.

Tools & Materials Required

To fix a leaky faucet, you'll need the following tools and materials:

• Adjustable Wrench: To loosen nuts and bolts
• Pliers: To unscrew faucet parts
• Screwdriver: To remove screws holding the faucet together
• Replacement parts: Washers, O-rings, aerators

If your faucet has an issue with splashing water, you may need to replace a faucet aerator. You can find a variety of these spare parts on Aerator.com.

Step-by-Step Instructions to Fix Your Leaky Faucet

Here is a step-by-step guide to fixing your leaky faucet prepared by our experts:

Step 1: Turn Off the Water Supply

Locate the shut-off valve, which is usually under the sink or to its side. Turn it clockwise to stop the flow of water. If you can't find the valve, you may need to turn off the main water supply.

Step 2: Plug the Drain

Before disassembling the faucet, plug the drain to avoid losing small parts. Washers or screws can easily fall down the drain.

Step 3: Disassemble the Faucet

Depending on the faucet type, use the appropriate tools to remove the handle and other components. Follow this diagram for guidance (example diagram).

Step 4: Inspect and Replace Worn-Out Parts

Carefully check washers, O-rings, seals, and aerators for signs of wear. Replace any damaged parts with new ones. Make sure to match the exact specifications to avoid further leaks.

Step 5: Reassemble the Faucet and Test

Reassemble the faucet, making sure all parts are tightened properly. Turn the water supply back on and test for leaks by turning the faucet on and off.

Step 6: Troubleshooting

If the faucet leaks persist, double-check the installation of the new parts and check that everything is secure. If issues persist, consider consulting a professional plumber.

Common Mistakes When Fixing a Leaky Faucet

When fixing a leaky faucet, you need to avoid common mistakes, such as:

• Over tightening screws and bolts
• Using the wrong or improperly sized replacement parts
• Failing to turn off the water supply before starting the repair

To prevent these mistakes, follow instructions carefully and double-check your work as you go.

When dealing with leaks, it's important to consider the type of faucet you have, as this will determine the appropriate repair method. Bathroom faucets, kitchen faucets, and bathtub faucets each have their unique mechanisms and potential issues. For example, a bathtub faucet might require different components for repair compared to a kitchen faucet. Identifying the correct type of faucet ensures that you use the right tools and replacement parts, making the repair process smoother and more effective.

Preventing and Fixing Leaks After Replacing a Faucet Aerator

Replacing an aerator can sometimes cause your faucet to drip or leak. This can happen for several reasons:

• Improper installation
• Overtightening the aerator
• Debris trapped in the faucet
• Worn-out internal components

To fix the problem, check if the aerator is screwed on evenly but not over-tightened. Clean out any debris dislodged during the replacement process and inspect internal faucet parts if the leak persists.

You can also run the faucet without the aerator for a few seconds to identify whether the problem lies with the aerator or another part.

The key to avoiding aerator issues is choosing a high-quality aerator that fits your faucet model. Aerator.com offers a wide range of reliable options.

After installation, regular maintenance can help prevent leaks and ensure smooth faucet operation. Learn more about proper aerator maintenance here and check out this guide on how to clean your aerator.
