Which routine maintenance task should be performed on pumping equipment?

• A. Inspect gauges and hoses
• B. Check oil, fuel, and battery
• C. Service priming equipment
• D. All of the above

Answer: (D)

Regular maintenance of pumping equipment involves checking several subsystems to catch wear or faults before they cause failure. Inspecting gauges and hoses keeps an eye on pressure, flow, and the condition of hoses for leaks or cracks that could fail under load. Checking oil, fuel, and battery ensures the engine and power system have proper lubrication, enough fuel, and a healthy electrical supply, preventing unexpected shutdowns. Servicing priming equipment maintains reliable suction and prevents air leaks or loss of prime, which is critical for pump performance. Since pumping systems rely on multiple components to operate safely and effectively, these checks should be done together as part of routine maintenance. All of these tasks should be performed.
