Which is the recommended pre-test check sequence before starting a pump test?

• A. Check engine oil and coolant levels; verify gauges and throttle; inspect hoses, fittings, and priming equipment for leaks or damage.
• B. Confirm the color of the paint on the pump.
• C. Set the radio channel and practice a drill.
• D. Measure ambient noise and wind speed.

Answer: (A)

Before starting a pump test, the essential step is a thorough pre-operational check of the engine and pump components to confirm fluid levels, instrument operation, and equipment integrity. Checking engine oil and coolant ensures the engine has proper lubrication and cooling so it won’t overheat or seize during the test. Verifying gauges and throttle is crucial for accurate monitoring of pressures, speeds, and engine control; you need to be able to read the system accurately and set the engine speed safely for the test. Inspecting hoses, fittings, and priming equipment for leaks or damage protects against sudden failures, pressure loss, or unsafe conditions once the pump starts and pressure rises. Priming equipment must be in good condition to establish a reliable prime, especially for suction operations, so the pump can develop the necessary flow.

Other options don’t address the operational readiness of the pump. The color of the paint is cosmetic and has no impact on safe operation. Setting a radio channel and practicing a drill are about communication or training rather than ensuring the pump is mechanically and hydraulically ready. Measuring ambient noise and wind speed relates to environmental conditions, not the pump’s ability to start and operate safely.
