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 LF150A 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.

Consists of a pre-charged air chamber that is rechargeable, an air-tight sealing cap, standard tire valve connection for easy charging, stainless steel top, sealed-in diaphragm, lower stainless steel chamber, and brass hex ad

Can be installed in new or existing plumbing systems in any angle
