Water hammer may happen occasionally, but it can cause a sudden plumbing failure or lead to damage over time. It may occur due to excess water pressure in supply lines, or perhaps plumbing pipes have come loose. Pumps, valves, expansion joints, gasketed joints, and welded joints can be seriously damaged, as can various fittings and connections.
