How To Stop Water Hammer Washing Machine. It could be from a toilet flushing, or the washing machine cycling, or perhaps a timed sprinkler system — in short, anything causing water to move through the pipes. Call a plumber and have a ‘pressure limiting valve’ or water hammer arrester installed.
Install water hammer arresters on washing machine taps. The washer will fill more slowly but it will still fill to the right water level. Ordinarily, plumbing pipes are designed to pressurise the water passing through them.
Instead of installing a vertical pipe near valves to capture and absorb pressure, the arrestors use a mixture of springs and air bladders to absorb water movement and reduce shock waves.
Disconnect the water supply from the washing machine. Water hammer is that loud thudding sound whenever the water stops entering your dishwasher or washing machine, or on turning off a tap. This is a piece of device that can be connected to your plumbing system to act as a cushion and absorb the shock caused by water hammer. The most effective means of controlling water hammer is a measured, compressible cushion of air which is permanently separated from the water system.
