A leaky faucet may seem like a minor nuisance, but over time, it can waste a significant amount of water and increase your water bill. In addition to the wasted water, if left untreated, the leak can cause damage to the surrounding sink or countertop. The good news is that fixing a leaky faucet is a simple DIY project that most homeowners can tackle themselves. By learning how to repair a leaky faucet, you can save money on plumbing costs and prevent further issues. Here's a step-by-step guide to help you fix that leaky faucet.

1. Turn Off the Water Supply

Before starting any repairs, it's essential to turn off the water supply to your faucet. You can find the shut-off valves under the sink. Turn both the hot and cold water valves clockwise to shut them off completely. After that, turn on the faucet to release any remaining water and ensure there is no pressure left in the pipes.

2. Plug the Drain

To prevent small parts, such as screws or washers, from falling down the drain during the repair process, plug the sink with a drain stopper or a rag. This simple step will save you time and frustration when working on your faucet.

3. Identify the Type of Faucet

There are several types of faucets, each with different components and repair methods. The most common types are:

  • Compression Faucets: These have two handles for hot and cold water and use a rubber washer to control water flow.
  • Cartridge Faucets: These have a single handle and use a cartridge to regulate water flow.
  • Ball Faucets: Often found in kitchen sinks, these faucets use a ball mechanism to control water flow.
  • Disc Faucets: These faucets feature a single handle and a ceramic disc to control water flow.

Identifying the type of faucet you have is crucial to know which parts to focus on during the repair.

4. Disassemble the Faucet

  • Compression Faucets: Use a screwdriver to remove the handle, usually by unscrewing the handle screw. Once the handle is off, use a wrench to remove the valve stem. At this point, you'll likely see a worn-out rubber washer or O-ring, which is typically the source of the leak.
  • Cartridge Faucets: After removing the handle, pull out the cartridge using pliers or a specialized tool. Inspect the cartridge for cracks or wear and tear that could be causing the leak.
  • Ball Faucets: You may need a special tool to disassemble ball faucets. After removing the handle, use the tool to remove the faucet cap and disassemble the faucet. Check for worn-out seals or O-rings.
  • Disc Faucets: Remove the handle and then the escutcheon (the decorative cover). Inspect the ceramic disc for any damage or worn seals that might be causing the leak.

5. Replace the Worn Parts

Once you've identified the damaged or worn-out parts, it's time to replace them. The most common parts to replace are:

  • Rubber washers or O-rings for compression faucets.
  • Cartridge or valve stem for cartridge faucets.
  • Seals or O-rings for ball or disc faucets.

It's important to take the old parts with you to a hardware store so you can find an exact match. A poorly fitting replacement part can lead to further leaks or damage to the faucet.

6. Reassemble the Faucet

After replacing the worn parts, reassemble the faucet in reverse order. Be sure all parts fit snugly and securely, but avoid overtightening, as this can cause damage to the faucet components.

7. Turn On the Water Supply

Once the faucet is reassembled, turn the water supply back on by opening the shut-off valves. Then, turn on the faucet to test it. Check for any remaining leaks around the handle or spout. If water is still dripping, you may need to check the parts again to ensure everything is correctly installed.

8. Test the Faucet

Finally, test the faucet thoroughly by running both hot and cold water. Make sure the faucet handles operate smoothly, and check for any leaks or drips. If the faucet continues to leak, it may be necessary to replace additional parts or consult a professional plumber.

Conclusion

Fixing a leaky faucet is a relatively simple and cost-effective task that can save you money on your water bill and prevent damage to your sink or countertop. By following these easy steps, you can repair the leak yourself and avoid the need for a plumber. Regularly maintaining your faucets and addressing issues promptly will help keep your plumbing system in good working order and reduce the risk of more expensive problems down the line.
