   The following characteristics may reduce or eliminate water hammer: Reduce the pressure of the water supply to the building by fitting a regulator. Lower fluid velocities. To keep water hammer low, pipe-sizing charts for some applications recommend flow velocity at or below 1.5 m/s (4.9 ft/s). Fit slowly closing valves.

4. Hydropneumatic device - Wikipedia

   en.wikipedia.org/wiki/Hydropneumatic_device

   Hydropneumatic water hammer preventers are chambers of sufficient volume to allow an extension of time in which a given flow may be accelerated or decelerated without sudden large change in pressure. See also expansion tank. When shock waves of an incompressible fluid within a piping system exist, especially at a high velocity, there is a high ...

5. Flushometer - Wikipedia

   en.wikipedia.org/wiki/Flushometer

   A narrow passageway leads from the main water supply into the pressure chamber. It is the narrowness of this passage that meters the flow by slowing repressurizing of the pressure chamber after the action of a flush. The diaphragm technology allows the flush valve to open and let water into the bowl. A main cylinder valve operates up and down.

6. Backflow prevention device - Wikipedia

   en.wikipedia.org/wiki/Backflow_prevention_device

   Water pressure may fail or be reduced when a water main bursts, pipes freeze, or there is unexpectedly high demand on the water system (for example, when several fire hydrants are opened). Reduced pressure in the pipe may allow contaminated water from the soil , from storage, or from other sources to be drawn up into the system.
