What checks should be performed before starting a pump?

• A. Verify water source and prime availability; confirm intake is open and discharge is closed; inspect hoses, gauges, fuel and oil levels, battery, and valve positions.
• B. Start the pump and check hoses.
• C. Only check water source; ignore other items.
• D. Prime the pump by turning on the priming device and then start.

Answer: (A)

Before starting a pump, you need to make sure the system is ready to accept water and won’t be damaged by the initial surge. That means confirming there is a reliable water source and that priming is available, so the pump can pull water rather than run dry. You should also verify the intake is open so water can enter, and the discharge is closed to prevent backflow or unwanted discharge as the pump comes up to speed. A quick inspection of the physical setup is essential: check hoses and connections for signs of wear or leaks, look at gauges to know what readings to expect once running, and confirm fuel and oil levels to keep the engine lubricated and fueled. Don’t forget the electrical side—ensure the battery and power connections are good—and set the valve positions correctly so water flows in the intended direction when you start. Skipping any of these items can lead to air locks, loss of prime, cavitation, or damage to the pump and equipment, so this comprehensive check helps the start-up be smooth and safe.
