All sprinkler pressure-reducing valves shall be inspected quarterly to verify they are in the following condition, except which one?

• A. In the Open Position
• B. In the Normal Operating Range
• C. In the Full Stroke Condition
• D. In the Closed Position

Answer: (D)

The important idea here is ensuring a pressure-reducing valve can operate freely and regulate pressure, not sit jammed in a nonfunctional state. During quarterly checks, you want to confirm the valve is able to move to start flow, estimate and maintain pressure within its normal range, and travel the full stroke to verify there’s no binding. So, the valve should be found in the open position, within the normal operating range, and capable of full stroke movement. These checks show the valve can open, regulate correctly, and fully move through its travel, which is essential for reliable operation in a sprinkler system. The one condition you don’t need to verify is being in the closed position. A closed position would stop flow and indicate a fault or misalignment, so it’s not a required state to confirm during routine quarterly inspections.
