Water hammer may produce an instantaneous pressure many times greater than the normal pressure. For this reason, many building codes now require the installation of a pressure limiting valve installed at the meter or a water hammer arrestor, a device designed to absorb these shock waves and to prevent damage to appliances such as washing machines.
