Backflow Prevention Devices: Testing and Commissioning

Safe drinking water relies entirely on the proper operation of containment and zone protection systems. This text-only course provides a comprehensive foundation in backflow prevention, helping you transition from general plumbing knowledge to specialized testing and commissioning. You will master the mechanics of fluid dynamics, identify potential hazards, and understand exactly how to keep water supplies safe from contamination. Through clear written explanations and structured technical breakdowns, you will develop a systematic approach to diagnosing and servicing water protection systems. This guide prepares you to perform essential field tests and recognize when a device requires repair or replacement. What you'll learn: - Understand the core principles of hydraulics, backpressure, and backsiphonage. - Identify different backflow prevention assemblies, including reduced pressure zone (RPZ) devices and double check valves. - Learn step-by-step procedures for testing and commissioning various backflow devices. - Troubleshoot common device failures and identify maintenance solutions. - Apply modern digital reporting and documentation practices for compliance logging. - Analyze risk levels to select the correct protection device for any installation. The course begins with foundational definitions, fluid mechanics, and regulatory frameworks before guiding you through detailed, written step-by-step testing procedures and troubleshooting scenarios. It is designed for licensed plumbers, apprentices, and water system technicians who want to specialize in backflow prevention. No prior backflow testing experience is required.
