Dosatron Water Hammer Arrestor Kit 3/4'' BSP

The Dosatron Water Hammer Arrestor Kit is an optional accessory for the Dosatron Hobby System. Dosatron's revolutionary Hobby System is a modular, multi-pump system ideal for home and hobby growers. A water hammer arrestor (WHA) is a device installed in a plumbing system to prevent the sound of water hammer – that loud banging noise that can occur when water flow in your water line is suddenly stopped by a closing valve. This noise is caused by a pressure wave that travels through the pipes when the flow in your water supply is stopped abruptly, and can cause damage to pipes, fittings, and appliances.
