Water Hamer Standardization



   Water Hammer is caused by the closing of a shut-off valve on a high pressure water supply. It usually occurs when a shut-off valve closes quickly, which causes a shock wave to reverberate in the water pipe, sometimes throughout the whole water system. It can usually be heard as one or more ‘thumps’ in the pipe work immediately following the closing of the valve.


CanWater Hammer Cause Damage?


   Yes, the shock wave caused when Water Hammer occurs can eventually cause damage in the system. It may cause a burst at any weak point in the pipe work or at a joint, and it can also cause damage to the inlet valves on washing machines, dishwashers, thermostatic showers etc. Likely Causes of Water Hammer Quick shut-off valves, as fitted to washing machines, dishwashers, thermostatic shower valves and other electricity controlled water operated appliances. Float operated inlet valves fitted in cisterns and other installations incorporating a water storage tank can suffer from certain symptoms of Water Hammer, particularly noisy vibrations.
