What term describes the pressure at which a sprinkler system normally operates?

• A. Low pressure
• B. Normal System Operating Pressure
• C. High pressure
• D. Very high pressure

Answer: (B)

Normal System Operating Pressure is the designated pressure a sprinkler system is designed to maintain during regular operation. This value ensures the right balance between pump output, pipe friction, and sprinkler flow so that each head receives adequate water when the system is activated. It’s the reference pressure the system is built around, not simply “low,” “high,” or a general state of the system. Static pressure is what you’d read with the system idle, and residual pressure is the pressure observed while water is actually flowing; those are different readings from the normal operating target. If the system pressure deviates from the Normal System Operating Pressure, it indicates a potential issue with the water supply, pump, valves, or piping that needs attention.
