Watts Series 150A Water Hammer Arrestor 1/2

Watts Series 150A Water Hammer Arrestor 1/2 Watts Series 150A Water Hammer Arrestor 1/2 MIP for Controlling Water Pressure Shock. Watts Series 105A water hammer arrestors should always be installed as close to the source of shock as possible - one unit on each hot and cold water line. 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 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. Operating Pressure: 150 psi working pressure. Maximum velocity 10 feet per second . Maximum shock pressure 200 psi. minimize
