Which describes the priming process in the suction line?

• A. The process of creating and maintaining prime to ensure the pump can develop flow.
• B. The process of increasing discharge pressure.
• C. The process of sealing flange connections.
• D. The process of venting air.

Answer: (A)

Priming the suction line means getting it filled with water and removing all air so the pump can draw water and develop flow. The best description is creating and maintaining prime to ensure the pump can develop flow. When air is left in the suction, the pump cannot create adequate suction, water won’t be drawn, and the system won’t reach proper discharge pressure. Achieving prime typically involves using a priming device or a method to pull water into the suction line and vent air until the line stays flooded. Venting air is part of priming, but the overall goal is a water-filled, air-free suction so the pump can deliver the required flow. Increasing discharge pressure is a result of operation after priming, while sealing flange connections isn’t part of priming.
