Fire Pump Run Practice Test

When you see a significant drop in discharge pressure while you’re holding the throttle, focus on finding and fixing the real source of the loss rather than trying to push harder. Systematic checks should include looking for air leaks in suction or discharge lines, valve positions that aren’t fully open, clogged lines or filters, and any sudden increase in downstream demand. As you identify a source, correct it while keeping the pump operating within safe limits. This approach addresses the actual cause of the pressure drop, helps prevent equipment damage, and maintains safe operation. Masking the problem by increasing throttle can overstress the pump and piping, shutting down the pump isn’t necessarily the right move unless there’s a hazard, and simply adding prime water won’t resolve a loss of pressure caused by leaks, blockages, or high demand.
