Because NFPA standards specify both flow and pressure, it is usually necessary to restrict the
flow somewhat to build up the pump pressure. In normal pumping, this restriction would be
caused by the friction loss in the lines. However, depending on line loss alone would require a
large amount of hose for some tests. It is common practice to use 50 to 100 ft of hose and gate
the discharge valves as required to maintain pressure.
