Contrary to popular belief, friction loss does occur between the hydrant and the attack pumper. Next time you train put a gauge on one of the 2 1/2" outlets and see the pressure difference between the hydrant and the intake on your pump. You will be amazed at the pressure drop when flowing the maximum amount of water with the set-up that you are working with.

I would recommend if you need big-water pump the hydrant. Another recommendation is to stretch 2 five inch supply lines from the hydrant to the supply pumper. This allows more water to flow into the pump at basically the same hydrant pressure.
