Rich,
That's why I said: "Define "backflow prevention". "
If there is not a definition of "backflow prevention" then the only real definition is that used in the codes (for the plumber to use) and a "high loop" is not going to be classified as "backflow prevention" in any code I am aware of.
Of the three listed, only an air gap is. Even a single check valve is not considered backflow prevention (at least I don't think it is).
Which lead to my little game of the HI writing it up and the plumbing saying a high loop is okay, with the HI saying ...
*IS* "backflow prevention" defined in the TREC standards? If not, let the games begin.
