Fixing a Leaking Outside Faucet When Hose Is Attached

Having an outside faucet, also known as a hose bib or spigot, is a convenient feature for any homeowner. It allows you to water your plants, wash your car, or carry out various outdoor tasks with ease. 

However, it can be frustrating to discover that your outside faucet is leaking when you attach a hose to it. Not only can this waste water and increase your utility bills, but it can also cause damage to the faucet and surrounding areas. 

In this article, we will explore the common causes of a leaking outside faucet when a hose is attached. We’ll also provide step-by-step troubleshooting and repair tips to help you resolve the issue.

Common Causes of Leaking Outside Faucets

Common Causes of Leaking Outside Faucets

Let’s explore some of the typical reasons why your outside faucet might leak when a hose is attached:

  1. Worn-out Washer: One of the most common culprits behind a leaking outside faucet is a worn-out or damaged rubber washer. 

This small yet crucial component resides inside the faucet and is responsible for creating a watertight seal when you turn on the faucet. 

As time goes by and with constant use, this washer can wear down, develop cracks, or lose its elasticity, ultimately leading to water seepage around the faucet handle.

  1. Loose or Damaged Connection: Another likely cause of leaks is a loose or damaged connection between the hose and the faucet. Over time, the frequent attachment and detachment of the hose can cause the connection to loosen. 

Additionally, wear and tear can lead to damaged threads on either the hose or the faucet, further contributing to water leakage when the faucet is turned on.

  1. Cracked or Split Pipe: If you live in an area with freezing temperatures during winter, your outside faucet is at risk of developing cracks or splits in the pipe

Water left inside the faucet can freeze and expand, exerting pressure on the pipe walls. When the faucet is used again after thawing, water can seep through these tiny openings, causing leaks during warmer seasons.

  1. High Water Pressure: While strong water pressure is essential for efficient water flow, excessively high water pressure can be detrimental to your outside faucet’s integrity. 

The intense pressure can strain the faucet and its components, particularly the seals. Over time, this stress weakens the seals and may lead to water escaping from the faucet when in use.
