Preventing Water Hammer from Damaging Pumps and Pipes

Water hammer is a shock wave passing down the pipe as a result of a sudden flowrate change. The most common cause is a valve closing too quickly, or a pump tripping or starting up suddenly. This causes a shock wave which starts at the valve or pump and passes along the pipe, changing the fluid velocity as it goes.
