What is Water Hammer? The noise from banging pipes is caused by shocks of high speed water flowing in the pipe when a fixture is suddenly closed. Sudden stoppage causes a “bounceback” of the water and 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 bounceback or shock. Dishwashers, clothes washers, quick-closing faucets all contribute to creating water hammer which is not only annoying but damaging to pipes and appliances. The simple, economical solution is Watts Series 150A designed with a pre-charged air chamber and a rugged sealed-in diaphragm which flexes to absorb the shock. It can be installed vertically, horizontally or at any angle.
