Water hammer is usually caused in high pressure (e.g. mains pressure) water systems either when a tap is turned off quickly, or by fast-acting solenoid valves, which suddenly stop the water moving through the pipes and sets up a shock wave through the water, causing the pipes to vibrate and ‘shudder’.

If an arrester doesn’t eliminate the water hammer, reduce peak flow by partially closing the water-supply valves. The washer will fill more slowly but it will still fill to the right water level. If that doesn’t work, consider a larger arrester or pressure reducing valves. (Hire a plumber to install those.)

What causes plumbing pipes to make a banging noise? If you hear a vibrating, banging or pounding noise when taps are turned on or off it’s usually due to hydraulic shock in your plumbing pipework. Hydraulic shock is more commonly known as “water hammer”. The banging noise you hear is the result of vibrations in pipes.
