Water Hammer Arrestors

Water hammer arrestors manufactured by Watts are used for absorbing shock when the water flowing in a piping system stops suddenly. When a shutoff valve, dishwasher, faucet or washer closes quickly and stops the flow, the momentum it creates shakes and pounds pipes. These water hammer arrestors prevent this condition using a cushion of air that can effectively absorb the momentum. Widely used in commercial and industrial applications, these water hammer arrestors prevent noise and damaging effects of water hammers to the pipes. Selected models have low lead body construction for more efficient operation.
