select the choice which best answers the following: what should be done before starting the pump? a) close the discharge valve b) check oil levels c) lubricate the shaft d) release trapped air

Answer

Brief Explanations:

Before starting a pump, it is crucial to check the oil levels to ensure proper lubrication and prevent mechanical failures. Closing the discharge valve is typically done during startup for centrifugal pumps but is not the first - step general check. Lubricating the shaft is a maintenance task that may not be a pre - startup check every time. Releasing trapped air is also important but checking oil levels is a fundamental pre - startup safety and maintenance check.

Answer:

B. Check oil levels
