What is the maximum end of the typical master stream nozzle flow range?

• A. 1250 gpm
• B. 150 gpm
• C. 500 gpm
• D. 100 gpm

Answer: (A)

Master streams are designed to deliver large volumes of water from a distance to overwhelm heavy fires, using large-diameter nozzles and higher pump pressures. In typical fireground practice, the practical maximum flow for a master stream nozzle is about 1250 gpm. This upper limit reflects what is reliably achievable with standard master stream gear while maintaining control and reach. Flows like 150 gpm or 100 gpm come from much smaller handlines, and 500 gpm sits in a mid-range that's common for some setups but isn’t the ceiling for typical master streams. So 1250 gpm represents the maximum end of what’s normally expected with standard master stream equipment.
