Cesar, do you know of NFPA 5000? It would not answer questions about local rules for back flow preventers but it seems to be used in a lot of countries other than the USA for the important basic rules. In fact, I was thinking the other day that, about 25 years ago I heard a rumor that NFPA 5000 was going to combine Fire AND Building Codes into one, over-all Standard, and keep the name 5000.
