1. A system for responding to pressure changes in a fluid, the system comprising:
a first piping subsystem that receives a first input flow;
a second piping subsystem that receives a second input flow, the second piping subsystem being independent of the first piping subsystem;
a third piping subsystem that receives the first input flow or the second input flow by respectively substituting for the first piping subsystem or second piping system; and
a test subsystem that simulates surge events and detects whether each of the piping subsystems properly vent pressure in response to one or more of the simulated surge events;
first and second pilots that detect a maximum pressure and a maximum pressure rate increase, respectively, in each of the piping subsystems; and
for each piping subsystem, an associated set of operating valves,
wherein each operating valve is sized in relation to a diameter of a respective pipe to which the valve is coupled,
wherein the substituting is performed by actuating the operating valves
wherein one or more operating valves associated with the first piping subsystem is of a different size from one or more operating valves associated with the second piping subsystem, and
wherein one or more operating valves associated with the third piping subsystem has a diameter at least as wide as a widest diameter from among the operating valves associated with each of the first and second piping subsystems.
