The AHJ mentioned that some of the more rural company filled their tankers and the like from ponds. In this jurisdiction ALL BFPs were RPZs because that's the SOP. I believe he cited (correctly as I recall) the International Plumbing Code. Any firemen out there putting backflow preventers on the hydrants prior to pumping out of them? Or perhaps setting up containment tents around the hydrant prior to popping the cap off?
