1. A method for testing responses of a system to one or more changes in a pressure of 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;
a test subsystem;
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, in the system;
each operating valve is sized in relation to a diameter of a respective pipe to which the valve is coupled;
the substituting is performed by actuating the operating valves;
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
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,
the method comprising, via the test subsystem:
simulating a surge event in a selected piping subsystem, the selected piping subsystem being one of the first, second, and third piping subsystems;
checking that the selected piping subsystem vents pressure in response to one or more of the simulated surge events.
