Pressure relief valves shall be tested every ______.

Pressure relief valves shall be tested every ______.

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

Answer: (D)

Testing frequency for a pressure relief valve centers on ensuring it will operate reliably in an overpressure event. Because this valve must open at a specified pressure and reseat properly after relief, it needs a formal functional test that verifies its set pressure, blowdown, and seating. In typical bulk oil storage facility practice, that formal test is performed at least once a year. This yearly interval balances confirming the valve will perform when needed with minimizing unnecessary disruption and maintenance costs. Between annual tests, regular visual inspections and instrument calibrations help catch obvious issues, and any sign of malfunction invites prompt retesting and repair. So, a yearly test is the standard expectation.
