How to Fix a Leaking Faucet

A leaking faucet might seem like a minor inconvenience, but over time, it can waste gallons of water and increase your utility bills. Fortunately, fixing a leaking faucet is usually a simple and inexpensive DIY task. In this guide, we’ll explore common causes of faucet leaks, step-by-step repair solutions, and tips for preventing future leaks.

Common Causes of a Leaking Faucet

Before fixing a leak, it’s important to understand why it’s happening. Here are some of the most common reasons your faucet may be dripping:

1. Worn-Out Washer

The rubber washer inside the faucet handle compresses each time you turn the water on and off. Over time, it can wear down, leading to leaks.

2. Faulty O-Ring

The O-ring is a small rubber seal in the faucet handle that prevents leaks. If it becomes loose or damaged, water may start dripping from the base of the handle.

3. Corroded Valve Seat

The valve seat connects the faucet and the spout. Corrosion due to mineral buildup can cause water to leak from the spout.

4. Loose or Damaged Parts

Nuts, screws, and other internal components may become loose or worn out, causing leaks.

5. High Water Pressure

If your faucet only leaks at certain times, such as when using other water fixtures, high water pressure may be the culprit.

Most faucet leaks can be repaired with a few basic tools, including an adjustable wrench, screwdriver, plumber’s tape, and replacement parts.

Step 1: Turn Off the Water Supply

Locate the shutoff valves under the sink and turn them clockwise to stop the water flow.
If you can’t find the shutoff valves, turn off your home’s main water supply.

Step 2: Remove the Faucet Handle

Use a screwdriver to remove the screw securing the handle.
Gently lift the handle to expose the internal components.

Step 3: Inspect and Replace Parts

Check the washer, O-ring, and valve seat for signs of wear or damage.
Replace any worn-out parts with new ones that match your faucet model.
Apply plumber’s tape to threaded areas to ensure a tight seal.

Step 4: Reassemble the Faucet

Put all parts back in place, ensuring they are secure.
Reattach the handle and tighten the screw.

Step 5: Turn On the Water Supply and Test

Slowly turn the shutoff valves back on.
Test the faucet to ensure the leak is fixed.

Preventing Future Faucet Leaks

To extend the life of your faucet and prevent future leaks, consider these tips:

Avoid over-tightening the handle, as this can wear out washers and O-rings more quickly.
Regularly clean the faucet to prevent mineral buildup and corrosion.
Check for leaks periodically and address small drips before they become bigger issues.
Install a water softener if you have hard water to reduce mineral deposits.

When to Call a Professional

While most faucet leaks are simple to fix, you should contact a plumber if:

The leak persists despite replacing washers and O-rings.
There’s a leak in the pipes beneath the sink.
You’re unsure how to disassemble or repair your faucet.

Conclusion

A leaking faucet is an easy DIY fix that can save homeowners money on water bills and prevent long-term plumbing issues. By identifying the cause of the leak and following simple repair steps, you can keep your faucets functioning efficiently. If in doubt, don’t hesitate to seek professional help to ensure your plumbing system stays in top shape.
