What is Water Hammer?

The noise from banging pipes is caused by shocks from high-speed water flowing in the piping system when a fixture is suddenly closed. A sudden stoppage of the water (a non-compressible liquid) flowing at a given pressure and velocity causes a surge or spike of water and is called a water hammer. When this occurs, a pressure wave travels back through the piping until it finds a point of relief.

The LF15M2 and LF15M2S Water Hammer Arrestors are designed to eliminate this effect. The LF15M2 and LF15M2S features Lead Free* construction to comply with Lead-Free* requirements. Dishwashers, clothes washers, and fast-closing positive shutoff valves incorporated in the system all contribute to creating water shock which is not only annoying but damaging to pipes and appliances.
