Quick opening devices, if provided, shall be tested how often without flooding the system?

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

Answer: (B)

Regular functional testing of quick opening devices is required to confirm they will operate reliably when needed, without letting water flow through the system during the test. The frequency chosen—every quarter—strikes a balance between catching wear or sticking early and avoiding unnecessary disruption or water loss. A quarterly test verifies the actuator and linkage operate and the device opens or functions as intended, all while using a non-flooding method that keeps the rest of the system intact. Testing more often, like monthly or weekly, would add wear and maintenance workload without a proportional gain in reliability. Testing less often, such as annually, risks a gradual failure going unnoticed until a real demand arises. Quarterly testing provides timely verification and keeps the system ready without introducing water into the piping during the test.
