Troubleshooting a Leaky Faucet: The Easiest Way to Replace a Washer

A leaky faucet is not only annoying, but it can also waste a significant amount of water and increase your water bill. If you’re experiencing a drip, drip, drip from your faucet, it’s likely due to a worn-out washer. Replacing a washer is a relatively simple and inexpensive fix that can be completed with basic tools and some DIY know-how. In this article, we’ll guide you through the easiest way to troubleshoot and replace a washer in a leaky faucet.

Identifying the Problem

Before you start, it’s essential to identify the source of the leak. Turn off the water supply to the faucet by locating the shut-off valves under the sink and turning them clockwise. Open the faucet to drain the water from the pipes. Then, inspect the faucet to determine where the leak is coming from. Common areas where leaks occur include:

  • The faucet handle or stem
  • The spout or aerator
  • The drain assembly

If the leak is coming from the faucet handle or stem, it’s likely due to a worn-out washer.

Tools and Materials Needed

To replace a washer, you’ll need the following tools and materials:

  • Adjustable wrench or basin wrench
  • Channel-type pliers (for removing old washer)
  • Needlenose pliers (for removing small parts)
  • Teflon tape
  • New washer ( matching the old one)
  • Silicone-based lubricant (optional)

Step-by-Step Instructions

  1. Disassemble the Faucet: Remove any visible screws or clips that hold the handle or stem in place. Gently pull the handle or stem away from the faucet body.
  2. Locate the Old Washer: Look for the old washer, which is usually located at the base of the stem or handle. It may be held in place by a small clip or screw.
  3. Remove the Old Washer: Use channel-type pliers to grasp the old washer and twist it counterclockwise to remove it. Be careful not to damage the surrounding area.
  4. Inspect and Clean the Area: Inspect the area where the old washer was located and clean out any debris or mineral buildup.
  5. Install the New Washer: Place the new washer in the same location as the old one, making sure it’s properly seated and aligned.
  6. Secure the New Washer: If the new washer has a clip or screw, use needlenose pliers to secure it in place. Apply a small amount of silicone-based lubricant to the washer to prevent corrosion.
  7. Reassemble the Faucet: Put the handle or stem back in place, making sure it’s properly aligned and secured with screws or clips.
  8. Turn On the Water Supply: Turn the shut-off valves counterclockwise to restore water supply to the faucet.
  9. Test the Faucet: Turn on the faucet to test it for leaks.

Tips and Precautions

  • Before starting the repair, make sure to turn off the water supply to the faucet to avoid any water damage or flooding.
  • Use Teflon tape to create a watertight seal on threaded connections.
