Daily Checks include Pump primer, pressure control, drive control, hose lines, cooling, fuel tank, suppression and all valves. Which item is included in daily checks?

• A. Pump primer
• B. Exterior lights
• C. Spare tire
• D. Radio battery

Answer: (A)

Daily readiness for a Mobile Water Supply system centers on confirming that the pumping system is ready to operate, including the ability to prime the pump. The pump primer is checked because it ensures the pump can be primed properly to establish a solid suction and draw water from the source. If the primer doesn’t function, air pockets or cavitation can prevent the pump from building pressure, delaying or stopping water flow when needed in a firefighting scenario. By verifying the primer works as part of the daily checks, you help guarantee the pump can be brought online quickly and reliably. Exterior lights, spare tire, and radio battery are general vehicle items, but they aren’t part of the daily MWS pump-check list described here.
