does anyone have the justification that added both requirements to 25. I can see backflow test after flowing water because these stupid devices fail so often but I'd certainly like to see a statistical analysis of failures to open, a data based probability of how how many of the anticipated inventory are expected to fail to open in a fire and the a cost/benefit analysis of doing this test. We're sticking backflows on every sprinkler system because once about forty years ago a sprinkler system may have been responsible for water smelling like onions. That's a lot of money that could have been invested in sub-prime loans instead.
