Dear Sirs: According to my experience there are two main reason to keep the test header close to the pump and prior to the main shut off valve:
1.- This arragment isolates the pump from the rest of the system. 2.- Water flow measured in points to far away from the pump will be afected by pressure droping across the pipe. Remember that the test header is just for pump flow test, in the same way a flowmeter is. So, as closer to the pump, more accurated will be the measuring.
