As a trusted plumbing professional with years of experience offering services to residents in Paramus, NJ, I can tell you that strange knocking sounds in your pipes are not something to be ignored. Known as 'water hammer', these sounds can signal potential issues within your plumbing system. Understanding what causes this knocking and how to address it can save you both time and costly repairs.

What is water hammer?

Water hammer is a common plumbing phenomenon that occurs when a valve closes suddenly at an end of a pipeline system, causing the water to stop or change direction abruptly. The resulting pressure shockwave creates a banging or knocking sound that can be heard throughout your home.

Causes of knocking pipes

1. High Water Pressure

One of the most common causes is excessively high water pressure. When water pressure exceeds the capacity of your plumbing system, it can lead to water hammer. Checking and regulating your water pressure can often mitigate these noises.

2. Loose Pipes

Pipes that are not securely fastened can move around in response to changes in water flow. This movement and banging against walls or other pipes can contribute to knocking noises. Securing these pipes can often resolve the issue.

3. Worn Out Valves

Older valves can wear out over time, leading to irregular water flow and the subsequent knocking sounds. Replacing worn out valves is part of regular maintenance that can prevent water hammer.

Why you should care

Ignoring these sounds can lead to severe consequences such as pipe damage or flooding, which are costly and disruptive to repair. For residents of Paramus, NJ, dealing with these issues as soon as they arise can prevent further damage. Regular inspections and maintenance from a professional offering plumbing in Paramus, NJ can help identify and resolve these issues.
