Water hammer is the name given to the effect of sudden pressure changes, also known as pressure shocks, in pipelines or other equipment. The stresses caused by these shocks are typically greater than those to which the equipment is usually subjected, or in fact designed to withstand. The shock wave, which travels with the velocity of sound, can cause deformation or even breakage of system components and equipment. The occurrence of water hammer is characterised by loud banging and knocking noises from within the system pipework.
