Why is the Faucet Leaking?

Never Ignore a Leaking or Dripping Faucet

A leaking or dripping faucet is more than just a nuisance. While it may seem like a minor annoyance, the truth is that allowing this issue to persist can have severe consequences for a homeowner’s home and wallet. The first problem with ignoring a leaking or dripping faucet is the potential for water damage. The longer someone waits to address it, the more costly the damage and repairs will be when the time comes. 

Even if a leaking or dripping faucet isn’t causing water damage, ignoring it can still cost homeowners. The water wasted from leaks, even a slowly dripping faucet, can add up quickly and spike water bills. If homeowners notice this issue at home, they should contact a plumber immediately. Taking care of leaks sooner rather than later can help save money and reduce the chance of costly damage to a home. This blog will share some of the most common reasons that cause faucets to leak. 


o ringWhen the O-ring in a faucet is worn out, it can cause dripping near the handle. An O-ring is a circular seal made from rubber or another pliable material that is used to create a watertight connection between two parts of a plumbing fixture or other machinery. The O-ring fits into an appropriately sized groove and is held in place by the pressure created when two pieces are joined together. 

Over time, this seal can wear out or become damaged, leading to leaks. When looking for evidence of a worn-out O-ring, it's essential to look at the area near the handle of a faucet, as water will often escape from there first due to the pressure created when turning the handle. Replacing a worn-out O-ring is an easy fix and can help prevent additional water damage and high water bills in the future.


A worn-out or corroded washer can cause leaking at the faucet's spout. A washer is an integral part of a faucet, as it is designed to seal off the connection between its internal parts and the plumbing in a home. When it becomes worn out or corroded, it can no longer provide the necessary seal, and water will begin to leak out.

The washer in a faucet can become worn out or corroded due to several factors. One of the most common causes is age and general wear and tear. Over time, washers may break down due to the constant pressure of water running through them. Corrosion can also be an issue, particularly in areas with hard water. It’s essential to ensure the new washer is correctly sized for the faucet to ensure a secure fit and prevent further damage or leaks. Replacing a worn-out or corroded washer can help keep taps functioning properly and reduce water waste.

Valve Seat

However, when a valve seat starts to corrode, it can no longer provide an effective seal, leading to leaking and dripping at the faucet's spout. Washers and valve seats can both cause leaking at the spout of a tap, but plumbers can accurately identify the cause upon inspection. 

Valve seats in faucets become corroded due to various reasons. One common cause is age and regular wear and tear. The buildup of minerals and other sediments, such as lime and calcium deposits, can also cause corrosion. Additionally, over-tightening of the faucet handle can contribute to valve seat corrosion, as it puts additional strain on the sealant and can cause it to weaken over time. Corroded valve seats should be replaced immediately to prevent further damage and water waste.
