Watts Lead Free* Water Hammer Arrestors 0750162

The noise from banging pipes is caused by shocks of high speed water flowing in the piping system when a fixture is suddenly closed. 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 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 elliminate this effect. The LF15M2 and LF15M2S features Lead Free* construction to comply with Lead Free* requirements.
