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.

Can be installed in new or existing plumbing systems in 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
