WHAT CAUSES WATER HAMMER?
Any action that can cause a rapid change in the velocity of the flow can set off a water hammer - closing a downstream valve, pipe
fracture, pump stoppage, etc. The critical time for which a valve may be closed depends on the length of piping between the valve
and the source reservoir. The longer the distance the slower the valve may be shut to cause a water hammer. Typically for short
lengths of pipe (below 500 ft) the critical time is less than 1/10 second.
WHAT CAN WATER HAMMER DO?
Pressure spikes from water hammer can raise fluid pressures to very high values (in excess of 1000 PSI depending on the situation).
Such pressure spikes can result in mechanical failures such as broken valves, pipes, strainers, joints, etc. Water hammer does not
have to occur fully to raise the pressure. A partial hammer can occur that raises the pressure to a certain percentage of the
theoretical maximum. The MLS In-Line Filter is rated to an absolute maximum pressure of 150 PSI for bolted lid models, 125 PSI for
band clamp lid models. A water hammer pressure spike that raises the pressure higher than the maximum rated pressure may result
in filter damage.
WHAT CAN I DO TO PREVENT WATER HAMMER?
There are precautions that can be taken to prevent or decrease the effect of water hammer. A pressure relief valve that leads to a
surge tank or accumulator may protect other key components from water hammer. A close adherence to operational policies will also
help prevent valves or pumps from being accidentally shut off thereby causing a water hammer. A close examination of a system will
alert you to the location of potential hazards.
