THAT is opening a can of worms. What NFPA 13 and 25 require is not Backflow testing in the same sense as is required by Oregon (or other jurisdictions). We are not testing the device for its ability to prevent backflow. We are flowing water through it to ensure it allows the design flow rate through the device. The backflow assembly doesn't even need to be touched, let alone opened or otherwise manipulated to conduct this test - no more than if you were conducting an inspector's test or main drain flow. Now you need to convince your plumbing AHJ of this fact... (If my experience with some of the jurisdictions in Oregon is consistent, they will now require backflow testing licenses for folks who conduct Main Drain and ITC tests)
