Water Hammer - it's Causes and Solutions

Causes of Water Hammer

Like any other moving fluid, flowing water has momentum.  When subjected to a sudden change in flow, shock waves propagate through the system.  This occurrence is referred to as ‘water hammer’.  Flow changes can occur due to the operation of valves, the starting and stopping of pumps, or directional changes caused by pipe fittings.  Other causes may be the rapid exhaustion of all air from the system or the recombination of water after water column separation.
