Thom, As an AHJ I run across this quite often, that is situations where a specific trades' work crosses many codes and standards. Unfortunately, but not always the trade is unaware of a legitimate code requirement that is outside their core documents, in the case of sprinklers the Building Code and NFPA-13. None the less as AHJ's we are legally bound to enforce the adopted codes and standards independent of any "contractual" or "trade" boundaries. I believe the industry needs to expand its interest and participation with regards to code development and or adoption.

(Water Supplier) The minimum for cross connection control of a Pollutant, (Fire Sprinkler Water without additatives) is a Double Check assembly. or Air Gap. Some water authorities have simplified their lives by requiring all backflows to be RPZ type.(No need to classify or check for change of use.) (Most will still allow the air gap, since its fool proof) (That is until some fool puts a hose on it and eliminates the gap)Whenever a fire engine connects to a FDC there is the possibility of cross connection. Eventually all engine's will be equipped with RPZ devices to prevent cross connection from their tanks or pumps, which may have had AFFF or Pond water as their previous source of contamination, or stagnation, similar to what occure's inside of the fire sprinkler system, occurring in vehicles that see little use. The backflow industry has done one hell of a marketing (Scare tactic's) job with the governments in this country, such that they are mandated everywhere, even tho the number of documented deaths each year was less than 10% of those that die by fire.
