Typical Reasons a Faucet Keeps Dripping

A dripping faucet can be a frustrating and costly problem.

A dripping faucet can be a frustrating and costly problem. It wastes water and can damage the plumbing system or even lead to flooding if left unchecked for too long.

Here are some common reasons why the faucet may be dripping or leaking:

Worn out washer

A worn-out washer is among the most common reasons for a dripping faucet. When the washer wears out, water can seep through the spout and leak. The good news is that replacing the washer is a relatively simple fix. It involves turning off the water supply, removing the handle, and replacing the washer.

Corroded valve seat

The valve seat is the connection between the faucet and the spout. Over time, the valve seat can become corroded, causing leaks. A rusty valve seat requires a professional plumber to fix it. They will remove the valve seat and replace it with a new one.

Loose or worn-out O-ring

An O-ring is a small rubber ring inside the faucet that helps create a seal. If the O-ring is loose or worn out, it can cause water to leak. Replacing the O-ring is a simple fix that involves disassembling the faucet and replacing the worn-out O-ring with a new one.

Worn out cartridge

A cartridge is a valve that controls the water flow in the faucet. Eventually, the cartridge will wear out and cause leaks. Replacing it requires turning off the water supply, disassembling the tap, and replacing the old cartridge with a new one. Note that this is a more complex fix that may require the assistance of a professional plumber.

Broken or cracked pipes

Broken or cracked pipes can cause water to leak from the faucet. This is a more serious issue requiring a professional plumber's attention. They must assess the damage and repair or replace the pipes as necessary.

The water pressure is too high

High water pressure in a home can cause faucets to drip constantly. When the water pressure in the pipes is too high, it stresses the tap and the plumbing system, leading to leaks and drips. The excess pressure can cause the internal parts of the faucet to wear out faster than usual, resulting in a constant drip even when the tap is turned off. Check the water pressure to ensure it's safe if the faucet is constantly dripping.

Get professional assistance

Understanding the typical reasons for a dripping faucet can help identify the problem and promptly find a solution. From worn-out washers to broken pipes, a tap may be dripping for many reasons. While some remedies are simple DIY fixes, others may require expert assistance.

If homeowners experience a dripping faucet, they should contact a professional plumbing service to assess the issue and provide the necessary repairs.
