The backflow preventer must be installed in an easily accessible location not subject to flooding or freezing. Said presumed cross connection hazards are as follows:
(1) Aircraft and missile manufacturing plants;
(2) Automotive plants, including those plants that manufacture motorcycles, automobiles, trucks, recreational vehicles, and construction and agricultural equipment;
(3) Beverage bottling plants, including dairies and breweries;
