The weekly test pertinent adjustments shall be made while the pump is:

• A. running
• B. idle
• C. stopped
• D. off

Answer: (A)

Adjustments during the weekly test must be made while the pump is running to observe the actual operating response. When the pump is in operation, you can see how changes to controls—like governor settings, throttle, and pressure-relief adjustments—affect speed, discharge pressure, and flow. If you tweak things with the pump stopped or off, you’re only changing static settings and won’t know if they achieve the desired performance under load. Running the pump also lets you verify proper interaction with the system, note any unusual vibration or temperature changes, and ensure alarms and interlocks respond correctly. So the adjustments are intended to be made during operation to ensure the pump delivers the correct pressure and flow in real conditions.
