Bathroom Sink Faucet Constantly Running: Causes and Fixes

A constantly running bathroom sink faucet is not only annoying but also wastes water and energy. Fortunately, fixing the problem is usually not difficult. This article will discuss some common causes of a constantly running bathroom sink faucet and provide step-by-step instructions on how to fix them.

Causes

There are several reasons why a bathroom sink faucet may start leaking continuously. Some of the most common causes include:

Worn-out Washer: The washer is a small rubber or plastic disc that sits between the faucet handle and the faucet body. Over time, the washer can become worn or damaged, causing it to leak water.
Damaged O-Rings: O-rings are small rubber or plastic rings that create a seal between the faucet handle and the faucet body. Like washers, O-rings can become worn or damaged over time, causing leaks.
Loose Faucet Handle: A loose faucet handle can allow water to leak from the base of the faucet.
Defective Cartridge: The cartridge is a small part that controls the flow of water through the faucet. If the cartridge is defective, it can cause the faucet to leak continuously.
