Water Leaking From Bathroom Sink Handle: Causes and Solutions

A leaking bathroom sink handle is a common plumbing issue that can waste water and increase your utility bills. While it may seem like a minor inconvenience, ignoring a leaking handle can lead to more serious problems down the road. In this article, we'll explore the common causes of water leaking from bathroom sink handles and provide step-by-step instructions on how to fix them yourself.

Causes of Leaking Bathroom Sink Handles

There are several potential causes for a leaking bathroom sink handle, including:

Worn or damaged O-rings: O-rings are small rubber gaskets that create a seal between the handle and the faucet body. Over time, O-rings can wear out or become damaged, allowing water to leak.
Loose handle screws: The screws that hold the handle in place can become loose, causing the handle to wobble and allowing water to leak around it.
Damaged cartridge or stem: The cartridge or stem is the main component inside the handle that controls the flow of water. If the cartridge or stem is damaged, it can cause water to leak.
Corroded or cracked faucet body: The faucet body can become corroded or cracked over time, creating a leak path for water.

How to Fix a Leaking Bathroom Sink Handle

Depending on the cause of the leak, you may be able to fix it yourself using the following steps:

1. Gather your tools

You will need:

Adjustable wrench
Allen wrench or hex key
Phillips screwdriver
Replacement O-rings (if needed)
Faucet grease

2. Turn off the water supply

Locate the water supply valves under the sink and turn them off to prevent water from flowing into the faucet.

3. Remove the handle

Use the Allen wrench or hex key to remove the screw that secures the handle to the faucet body. Pull the handle straight up to remove it.

4. Inspect the O-rings

Examine the O-rings for any signs of wear or damage. If the O-rings are damaged, you will need to replace them.

5. Tighten loose screws

Use the adjustable wrench to tighten any loose screws that hold the handle in place.

6. Lubricate the handle and O-rings

Apply a small amount of faucet grease to the O-rings and the threads of the handle. This will help to create a watertight seal and prevent future leaks.
