Bang - Bang - Bang from your Laundry Room?    What is Water Hammer?

Water Hammer - the noise from banging pipes is caused by shocks from stopping high speed water flow in the pipe when a valve is suddenly closed at a plumbing fixture or appliance. Sudden stoppage causes a "bounce back" of the water. This is called water hammer. It might be compared to driving your car at slow speed into a wall where the effect is negligible. However, if you drove the car at a much higher speed, the impact would be greater, and consequently so would the bounce back or shock.

Dishwashers, clothes washers, ice makers, irrigation valves, faucets or other quick closing, electrically controlled valves that are operated automatically can all contribute to creating water hammer. Water Hammer is not only annoying but damaging to pipes and the appliances that are connected to your water system too. The simple, economical solution is Watts No. 150A-HA designed with a swivel 3/4 female hose X 3/4 male hose tee and a pre-charged air chamber installed it the middle of a tee designed to fit on the 3/4" hose connections, which are the universally standard connections of laundry washing machine shut off valves in North America.
