Why Your Bathroom Sink Faucet Is Leaking And What You Can Do About It

A leaky bathroom sink faucet is not just an annoyance; it can also waste water and increase your utility bills. Identifying the source of the leak is crucial for effective repairs. In this comprehensive guide, we delve into the various reasons why your bathroom sink faucet may be leaking and provide practical solutions to restore its functionality.

Common Causes of Bathroom Sink Faucet Leaks

1. Worn Washers

Washers are small rubber or plastic seals that create a watertight seal between the faucet handle and the valve stem. Over time, these washers can become worn or damaged, allowing water to leak.

2. Loose Handle

A loose handle can cause the faucet to leak because it allows water to escape through the gap between the handle and the faucet body.

3. Faulty Cartridge

Cartridges are self-contained units that control the flow of water in many modern faucets. A faulty cartridge can allow water to leak from the faucet.

4. Damaged O-Rings

O-rings are small rubber seals that create a watertight seal between the faucet body and other components. Damaged O-rings can allow water to leak.

5. Corroded Pipes

Corrosion can weaken the pipes that connect the faucet to the water supply, leading to leaks.

6. Mineral Buildup

Mineral buildup from hard water can clog the faucet’s aerator and restrict water flow. When the water pressure builds up behind the blockage, it can cause the faucet to leak.

7. Loose Aerator

The aerator is a small device attached to the end of the faucet that helps to create a smooth flow of water. A loose aerator can allow water to leak from the faucet.

DIY Solutions for Bathroom Sink Faucet Leaks

1. Replace Worn Washers

Replacing worn washers is a quick and easy fix for most faucet leaks. Simply turn off the water supply, disassemble the faucet handle, and replace the old washers with new ones.

2. Tighten Loose Handle

Use a wrench or pliers to tighten the handle to eliminate the gap between the handle and the faucet body.

3. Clean or Replace Aerator

Remove the aerator and clean it with vinegar or a commercial descaling solution. If the aerator is damaged, replace it with a new one.

4. Replace O-Rings

Identify the damaged O-rings and replace them with new ones. Make sure to use the correct size and type of O-ring for your faucet.

When to Call a Plumber

In some cases, it may be necessary to call a plumber to repair a bathroom sink faucet leak. If the leak is caused by:

• Corroded pipes

To prevent future bathroom sink faucet leaks, follow these tips:
