Finally getting to one of my New Year's resolutions and taking the Back Flow Cross Connection Certification course and exam next week. 40 class room hours in one week. Fortunately half the time is hands on. I am taking the class through the American Water Works Association. Considering the Certified Landscape Irrigation Auditor for next year. "This course (half lecture and half hands-on training) provides the testing and maintenance methods for backflow prevention assemblies. Participants will learn how to recognize various backflow preventers and the proper procedures for testing each assembly under a variety of test conditions. This course will review all the rules, codes, and regulations on backflow requirements."
