How to Replace a Washer in a Bathroom Sink Faucet

A leaky faucet can be a source of frustration and waste. Often, a simple washer replacement can resolve the issue. This guide will provide step-by-step instructions on how to replace a washer in a bathroom sink faucet, equipping you with the knowledge to tackle this common plumbing repair.

1. Gather the Necessary Tools and Materials

Before embarking on the repair, ensure you have the following tools and materials readily available:

A screwdriver set (Phillips and flathead)
Adjustable wrench
Basin wrench
Channel-lock pliers
Replacement washer (compatible with your faucet)
Teflon tape
Bucket or container
Towels
Optional: Work gloves

It's important to choose a replacement washer that is compatible with your faucet. You can find this information on the manufacturer's website or by visiting a local hardware store.

2. Turn Off the Water Supply

Safety is paramount. Before beginning any plumbing work, turn off the water supply to the sink. This is usually achieved by turning the shut-off valve located beneath the sink or on the wall. Once you've turned off the valve, run the faucet to ensure all water has drained.

3. Remove the Faucet Handle

Depending on the type of faucet, the handle removal process may vary. For most commonly used faucets, you can follow these steps:

Locate the set screw on the handle. This may be visible or concealed under a decorative cap.
Use a screwdriver to loosen and remove the set screw.
Carefully pull the handle off the faucet stem.

4. Remove the Faucet Stem

The faucet stem is the long, metal rod that connects the handle to the faucet body. To remove it, you'll need to use a basin wrench.

Position the basin wrench around the faucet stem, ensuring that the jaws are securely gripping the stem.
Turn the wrench counterclockwise to loosen the stem. It may require some effort to break the stem free.
Once the stem is loose, carefully remove it from the faucet body.

5. Replace the Washer

The washer is a small, rubber or plastic disc located at the bottom of the faucet stem. It creates a seal to prevent leaks. To replace the washer, follow these steps:

Inspect the old washer for any signs of wear, such as cracks, tears, or hardening.
Carefully remove the old washer from the stem.
Place the new washer onto the stem, ensuring it is properly seated.

6. Reassemble the Faucet

Once the washer has been replaced, you can reassemble the faucet in reverse order.

Insert the faucet stem back into the faucet body, turning it clockwise to tighten it securely.
Reattach the handle to the stem and tighten the set screw.
Turn the water supply back on, slowly at first, to check for leaks.
If necessary, tighten the faucet stem or handle further to eliminate any leaks.

7. Test for Leaks

After reassembling the faucet, run the water and check for any leaks. If you notice any leaks, tighten the faucet stem or handle further. If the leak persists, it may indicate a more significant issue that requires professional attention.

By following these steps, you can effectively replace a washer in your bathroom sink faucet and resolve a common plumbing problem. Replacing a worn-out washer is a straightforward repair that can save you money and prevent further damage.
