The Effects of Water Hammer. While it may look and sound harmless, the impact force on the valve – caused by the fluid's momentum – can create pressure spikes that may exceed ten times the working pressure of the system. These sudden stoppages of flow and the resulting increases in pressure from the shock waves can cause significant damage to the overall piping system either due …
