Water hammer is a relatively common plumbing phenomenon that can be heard when the flow of water suddenly stops or reverses direction and rattles your plumbing. This noise is often heard in older homes with metal pipes. The resulting bang coming from your water pipes can be unsettling, but your plumbing contractor is equipped to handle the issue.

A Brief Guide to Water Hammer

What causes water hammer?

When a valve or appliance shuts off water flow, leftover water can get caught in the air chambers. These vertical pipes are designed to help regulate pressure in your plumbing. Modern homes have air chambers installed at critical points throughout the house to prevent the flow of water from surging. 

When a line is shut off, the sudden stop or backflow of water can cause a shock wave that reverberates through your plumbing. This hydraulic shock is common in homes that lack an adequate number of properly positioned air chambers.

Does water pressure affect water hammer?

While the liquid inside an air chamber causes water hammer, the pressure on your system is the ultimate culprit. The higher the water pressure, the more likely you are to experience this problem. 

If you’re in an area where municipal water pressure is abnormally high, plumbing contractors can install a pressure device on the water main to reduce the stress on your system.

Does water hammer damage my pipes?

Over time, the hydraulic shock in your plumbing can erode your pipes. In extreme cases, where too much unregulated pressure stays in your system, pipes can burst. 

What can plumbing contractors do to fix water hammer?

There are a couple of solutions your contractors can implement. If your home doesn’t have the proper number of air chambers to regulate pressure, a plumber can install them at key points in your system.

Another solution is installing a water hammer arrestor. This device is similar to an air chamber but seals the piping with a diaphragm valve or piston to prevent the backflow of water that causes hydraulic shock.
