How will I know if the backflow preventer I'm installing is an approved device?

The American Society of Sanitary Engineering (A.S.S.E.) has performed the necessary research and developed the standards accepted by the Wisconsin Department of Natural Resources, the Wisconsin Department of Commerce, and the Marinette Water Utility. Any device that is labeled with an "A.S.S.E. number" will be considered as an approved backflow prevention device. Toilets tank fill devices must be labeled with A.S.S.E. Number 1002. Different plumbing situations will require different styles of backflow preventers. The inspection form provided by the Utility's inspector will list the required A.S.S.E. number which needs to appear on each device, depending on the type of backflow protection needed.
