No it does not change it. Your concern is with testing the pump at churn, 50, 100, and 150 rated. You use the test header control valve to control the flow, the control valve serves the same purpose as the individual hose valves.

If we are to do the test each year in a consistent manner to observe the water figures and pump figures can it be changed? Going from 6-2.5 hose connections to 1-4 inch connection would change the test data significantly. Or does it?

That's what I did on the test header at our office...... Works GREAT. One 4" X 10' hose, one big hose monster, throttle the valve and get a great test curve in a few minutes with one guy.

The test header has 4 hose connections. Inspection team tells customer that the test header needed 4 more valves in order to do the test. Customer calls and ask where thats written that each connection is rated for 250 gpm. NFPA 20 (2003) governs and table 5.25b says it only needs a total of 6. Am I looking in the right spot?
