This course is designed to teach the student the theory behind backflow preventer design and operation and proficiency in testing backflow prevention assemblies, including "troubleshooting" and diagnosis of problems. Its primary purpose is to prepare the student to take the American Water Works Association, California/Nevada Section, written and practical exams, the American Backflow Prevention Association (ABPA) written and practical exams and various county certification exams. Definitions, the laws governing testers, types of backflow prevention assemblies and their application, degree of hazard, hydraulics and installation requirements will be covered.
Student Learning Outcomes:
1) Student will understand the sections of the California Administrative Code and State Plumbing Code and local ordinances or local operating rules which apply to the annual testing of backflow prevention devices.
2) Student will demonstrate the ability to correctly field test the Reduced Pressure Backflow Preventer, Double Check Valve Assembly, Pressure Vacuum Breaker and the Spill Resistant Pressure Vacuum Breaker in order to obtain required certifications from local water utilities, local county health departments and certification agencies such as the California Section of the American Water Works Association or the American Backflow Prevention Association. Student will also be able to identify the proper installation of Air Gaps.
3) Student will demonstrate the ability to correctly diagnose problems with the backflow preventers during the annual test and be able to state the correct repair procedure for the backflow preventer.
4) Student will be able to identify and compare the degree of hazard of cross-connections in order to determine the appropriate backflow prevention device to be installed in order to protect public health.
