When your plumbing system is operating normally, the process of using faucets and water appliances should be relatively silent. If turning a valve off or on results in loud banging noises reverberating through your pipes, it’s referred to by plumbers as water hammer. Here are a few questions about this problem, so you know what to do about noisy pipes. 

The Top 4 Questions About Water Hammer Answered

What causes water hammer?

Water hammer is caused by an increase in pressure when a faucet or valve is turned on or shut off. When the liquid flowing through your pipes has to suddenly change direction, a hydraulic shock occurs, and it may bang against the sides of the pipe, causing a loud noise.

This can occur when vertical air chambers are full, household water pressure is too high, or when older pipes are not sufficiently secured into the walls, thus increasing the risk of movement and components banging up against each other during sudden changes in pressure. 

Does this issue cause pipe damage?

At first, this plumbing issue may simply be frustrating since the loud noise can be distracting as you go about your day.

In time, water hammer can lead to erosion within your pipes and premature damage due to added movement and pressure. Immediate action is highly recommended, or you may experience additional trouble, such as leaks or even burst pipes. 

How can you prevent water hammer?

You can prevent water hammer by checking your vertical air chambers to make sure they’re empty. Other prevention tactics include lowering your household water pressure or installing new plumbing pipes that are properly secured to the walls. 

Should you call a plumber to fix this issue?

It’s best to hire an experienced plumber since they can provide a comprehensive inspection and evaluation of your plumbing system to pinpoint the issue.

Depending on the cause of your water hammer, they can open or close valves as needed, empty air chambers, install new ones, update old pipes, and install brand new piping systems to eradicate the problem safely and efficiently.
