Well, is it a 4x4 Storz, a 5x4 storz, or a 2.5" NST/bastard? Also, in other than high-rises or where an automatic water supply for the standpipe is required, the FDC IS the primary water source for a manual wet standpipe, so the flow in needs to meet the demand of the standpipe system in those instances- well, if we want it to work anyway....

Just because it is the same piece of equipment doesn't mean that they have the same objectives or levels of criticality. Try submitting a proposal next cycle showing the friction loss and try to change it. WHat is the loss at 250 gpm and 500 gpm?
