Suction, discharge, bypass, and isolation valves will be supervised in which position?

Suction, discharge, bypass, and isolation valves will be supervised in which position?

• A. Open
• B. Closed
• C. Half-Open
• D. Blocked

Answer: (A)

When you’re supervising a pumping or line system, you want a clear, controllable flow path that you can observe and test easily. Keeping suction, discharge, bypass, and isolation valves in the open position ensures there’s no blockage hiding a fault and that flow can be started, stopped, or redirected without surprises. If any of these valves were closed or only partially open, you could mask leaks, misread pressures, or miss abnormal valve behavior, and you’d lose immediate flow control needed for safe operation. A fully open, ready-to-operate state supports reliable monitoring and quick response, whereas other positions create uncertainty and potential hazards.
