The Elkhart 1 inch Booster Line Chief Nozzle is rated at how many GPM and PSI?

• A. 30 GPM/100 PSI
• B. 20 GPM/80 PSI
• C. 40 GPM/120 PSI
• D. 50 GPM/150 PSI

Answer: (A)

The rating being tested is the nozzle’s published flow at its designed operating pressure. For the Elkhart 1 inch Booster Line Chief Nozzle, the nozzle is specified to deliver about 30 gallons per minute when the nozzle pressure is 100 psi. This combination—30 GPM at 100 psi—is chosen because it provides a practical, controllable stream for a 1-inch booster line: enough flow to knock down small to medium fires while keeping the nozzle and hose handling manageable for firefighters. At higher pressures or flows, this model isn’t rated to perform as specified, which could lead to over-pressurizing the line or exceeding the nozzle’s design limits. Lower flows at lower pressures would not meet the nozzle’s rated performance, and wouldn’t reflect what this specific nozzle is designed to deliver.
