Which items are included in a routine pre-run test?

• A. Oil and fuel levels; battery charge; belts; wiring.
• B. Oil and fuel levels; battery charge; belts; wiring; priming; gauge accuracy; water source availability; proper valve positions; line checks.
• C. Battery charge and hose alignment.
• D. Belts and wiring.

Answer: (C)

A routine pre-run test is about confirming the pump and its supporting systems are fully ready to operate. It isn’t enough to check just one or two things; you need to verify power, mechanical condition, priming, and the ability to actually draw and deliver water. That means checking oil and fuel levels to ensure the engine will run, battery charge and wiring and belts to confirm the electrical and drive systems are sound, and then confirming priming so the pump can develop suction. You also need to trust the gauges by verifying gauge accuracy, ensure a water source is available, set proper valve positions, and perform line checks so hoses and connections are ready and free of defects. Hose alignment by itself doesn’t cover these critical readiness checks, so the most thorough routine pre-run test includes all these elements together.
