A full flow test on the master pressure regulating device shall be conducted how often on each valve and compared to previous test results?

A full flow test on the master pressure regulating device shall be conducted how often on each valve and compared to previous test results?

• A. Weekly
• B. Monthly
• C. Annually
• D. Daily

Answer: (C)

Testing the master pressure regulating device at full flow checks that it still delivers the correct pressure during maximum demand and that its setting hasn’t drifted from the last measurement. Because this device influences the entire system, you want to track its performance over time to catch gradual changes due to wear, debris, or calibration drift. The standard practice is to perform a full-flow test on an annual basis and compare the results to the previous test to confirm consistency or to identify a trend that requires adjustment. More frequent testing like daily, weekly, or monthly isn’t warranted for this component since it doesn’t normally change rapidly; waiting a year ensures we balance reliability with practicality. If the current test shows a meaningful change from the prior result, you’d investigate and correct before the next annual check, using the trend as a guide for maintenance.
