Hydraulic in general suffers from the same problem in all its aspects, which is the phenomenon of Anti Water Hammer as the pressure oscillation above or below the nominal pressure, as a consequence of rapid fluctuations in speed during the flow of a fluid through a pipe.
The anti water , in the end, are nothing more than large hydro-pneumatic accumulators, they are safety devices to avoid damage caused by anti water hammer, which occur due to unscheduled pump stops or unexpected closings of valves in drinking water or raw water pipes.
