Water hammer is a pressure surge or wave caused when a fluid (usually a liquid but sometimes also a gas) in motion is forced to stop or change direction suddenly (momentum change). Water hammer commonly occurs when a valve closes suddenly at an end of a pipeline system, and a pressure wave propagates in the pipe.

This pressure wave can cause major problems, from noise and vibration to pipe collapse. This water hammer arrestor device is designed to prevent the impact that this has on water pipes and also water filters or housings that may also be present on the line.

This device could potentially save you thousands of dollars in damage if you are not at home when leaks in damaged pipes occour and in alot of cases landlords or homeowners/insurance people do not look favourably at houses that have taken no precautionary measures in protecting their home.
