Per Ohio Admin Code Rule 1301:3-7-02 in order to test backflow preventers, you have to pass an exam given by the Department of Commerce - Division of Industrial Commerce, and you have to take a 24-hour course with an approved training agency and have at least five years experience in either the plumbing or water operating industries ( other relevant experience may count at their discretion )
So you take a course and then sit for an exam with the state, the application to the state is downloadable here - and their full backflow prevention tester manual is downloadable here
Currently, no, but we have been hoping to set something up at some point in the future.
All of our courses utilize the University of Southern California, Foundation for Cross Connection Control and Hydraulic Research ( USC-FCCHR ) 10th Edition testing procedures and diagnostics, using derivative materials and auxiliary tests if applicable by the local authorities.
On our YouTube Channel, we created a series of videos explaining the testing procedures:
