Everything You Need to Know About Water Hammer

Water hammer is often brushed off as just a minor inconvenience, but it can signal a more serious plumbing issue. Instead of ignoring the problem, it’s important to understand what water hammer is and why it’s worth addressing. Our trusted team of plumbers and AC repair contractors at onlineplumber is here to provide you with essential insights about water hammer.

What Is Water Hammer?

In an average household, water travels under significant pressure, required for delivering it efficiently throughout the home. Many homeowners habitually turn faucets and other water appliances on and off without a second thought. But, if you suddenly hear a loud, banging noise after shutting off a fixture, that’s water hammer at work. This noise occurs when the high-pressure water flow is abruptly stopped, leaving the pipes to absorb the sudden change. As a result, you get that distinctive banging sound caused by the shockwave of pressure.

How to Address Water Hammer

Ignoring water hammer is not a wise choice. The strong vibrations caused by it can lead to damages akin to those from an actual hammer striking the pipes. Luckily, resolving this issue doesn’t require a degree in plumbing or HVAC technology. Here are a few practical solutions you can consider:

  1. Correct Plumbing Installation Errors – Inexperienced plumbers may make critical mistakes by placing 90-degree turns in the plumbing. Just like a car can’t make sharp turns without slowing down, water under high pressure can’t navigate these abrupt angles efficiently, potentially requiring some plumbing replacements.
  1. Reduce Water Pressure – If you encounter water hammer whenever using fixtures around the house, it could be a sign that your water pressure is too high. Lowering that pressure may resolve the issue.
  1. Install a Water Hammer Arrester – If the banging occurs only with a specific fixture, consider installing a water hammer arrester (or in-line water surge arrester). This device can be added to your plumbing system, creating an air pocket that helps absorb the pressure during surges.
