Water Hammer Arrestor Kits

Water hammer arrestors are used to prevent the potential damaging effects of water hammer which is defined as a pressure surge or wave caused when a fluid in motion is forced to stop or change directions suddenly.

For installations with strong water hammer potential such as using quick closing solenoid valves, we recommend using a Water Hammer Arrestor Kit.
