Water hammer is a pressure surge or wave caused when a fluid in motion is forced to stop or change direction suddenly. This sudden change in momentum creates a shockwave that travels through the pipe, often producing a banging noise. Causes of water hammer: • Sudden closure of valves: Quick-closing valves, like those in washing machines or dishwashers, abruptly stop water flow. • High water pressure: Excessive pressure in the plumbing system can exacerbate the effect of sudden flow changes. • Long pipe runs: Longer pipes allow more momentum to build up in the water, leading to a stronger surge when stopped. • Loose pipes: Pipes that are not properly secured can vibrate and bang against surrounding structures during a water hammer event. Remedies of water hammer: • Install water hammer arrestors: These devices absorb the shockwave by providing an air cushion or spring mechanism. • Use slow-closing valves: Replacing quick-closing valves with slower-acting ones reduces the abruptness of flow stoppage. • Reduce water pressure: Installing a pressure reducing valve (PRV) can lower overall system pressure. • Secure pipes: Properly fastening pipes with clamps and hangers prevents them from moving and banging.
