For Washington State, we offer a prep course that will prepare you to take the State's Exam. The class is not a hard pre-requisite, but it would be hard if not impossible to sit for the exam without taking a formal backflow course at some point.
Our 40-hour course is based on the USC (University of Southern California) textbook and course materials. Our 40-hour certificate program is acceptable to ABPA as the pre-requisite training for the backflow tester exam and license if you plan to use in other states. Links to the ABPA Exam Application and Certification Manual are below. The certification exam requires formal training and/or experience in order to apply, which our 40-hour course diploma is valid for this use and you just include the course info with your application.
Backflow Prevention Assembly Testing in Washington is regulated by the Department of Health, where they have the program administered by Washington Certification Services. You have to take a written and practical exam, based on the USC 10th Edition manual and testing procedures.
Do you need a backflow test kit or need to calibrate a test kit you already have? We offer both of these, check out our sister company Kruger Instruments for more information:
