When pressure readings indicate deterioration, which action should be taken to verify the adequacy of the pressure?

• A. Compare results with the required design pressure.
• B. Notify the Authority Having Jurisdiction.
• C. Take pressure readings from a gauge placed at the hydraulically most remote valve.
• D. Look for closed control valves.

Answer: (A)

When pressure readings begin to deteriorate, the first thing to do is check against the system’s design requirements. Compare the measured pressure to the required design pressure to see if the current values still meet what the system was designed to deliver. If the readings are at or above the design pressure within tolerance, the system is still adequately pressurized despite the deterioration in readings elsewhere. If the measurements fall short of the design pressure, it indicates under-pressurization and warrants investigation into causes such as pump performance, leaks, valve positions, or line restrictions. Comparing to design pressure provides the definitive baseline for adequacy; other steps may help diagnose causes, but this comparison confirms whether the pressure is sufficient for proper operation.
