Why Does It Always Have to be Done That Way?
Myth 13: A 2-1/2” handline can flow up to 350 GPM. Flows higher than this can only be done with a master stream appliance.
Reality: Handline streams reaching up to 500 GPM are entirely possible using a 2-1/2” or 3” handline. A line flowing this much water should not be handled in the standing up mode, instead a minimum of two firefighters should be sitting on the line. There are several nozzle manufacturers that now market 500 GPM handline nozzles.
This 3” handline is flowing 600 GPM
