Good stuff even today the basics work well. Remember that at one time if an FDNY required Engine Companies other than 1st or 2nd due on the box must use a 4 1/2" hard suction for hydrant hook ups at serious fire so the hookup supply will not collapse if the hydrant or hookup draws a vacuum or near vacuum. The bigger the fire/s, the smaller the water main, the more discharges the pumper the greater the danger of "running away from the water" and the supply line/suction hose collapsing causing a danger to firefighters operating the hoseline or large Caliber stream device. Make sure if you are responding on a multiple alarm or other serious fire that you are using the largest "Hard Suction" possible.
