Summary: Swapping to low-pressure, fixed-flow nozzles reduced pump discharge pressures and nozzle reaction for one department — boosting maneuverability and increasing flow without overworking the engine. Initially met with resistance, the change proved itself on the fireground and won over every crew member involved.
Why This Department Switched to Low-Pressure, Fixed-Flow Nozzles
High pump discharge pressures and excessive nozzle reaction were making things harder than they needed to be for Asst. Chief Amy West and the Taber, Alberta fire department. Like a lot of departments, they were running nozzle and hose setups that demanded more from the pump — and from the crews trying to handle them.
The Problem: High Pressure, Heavy Reaction
The original nozzle and hose combinations were driving up pump discharge pressures and creating tough nozzle reaction. That meant less control, more fatigue, and an overall harder time getting water where it needed to go. It pushed one firefighter to dig deeper and look for better options.
The Change: Fixed Flow at Lower Pressure
After reviewing different nozzle solutions, the department landed on a combination of low-pressure, fixed-flow nozzles. This setup delivered:
-
Higher actual flow rates
-
Lower required pump pressures
-
Significantly reduced nozzle reaction
The Results: Easier Operation, Better Flow
The change wasn’t just about smoother operation — it produced measurable results. Crews found it easier to handle lines, maneuver in tight spots, and keep water flowing without overworking the engine. Even with higher flows, everything ran cooler and cleaner.
The Resistance: Skepticism Turned Support
Not everyone was on board at first. But once the results showed up on the fireground, resistance disappeared. “There wasn’t a single person that was against the change,” West said. “They all saw the results”.
