A vital part of a Reduced Pressure Zone (RPZ, also known as a Reduced Pressure Principle or RP) Backflow Preventer is the relief valve. While this component is crucial to the operation and level of safety provided by the backflow preventer, in certain situations it will open and release potentially large quantities of water. Learning why this happens, how to determine the cause of an open relief valve, and measures you can take to both prevent large discharges of water and mitigate them if they happen is vital for any engineer, contractor, plumber, or building owner.

Course Objectives: 

• Discuss RPZ backflow preventer operation
• Describe root cause analysis of RPZ backflow preventer discharge
• Examine worst case discharge
• Explain strainer installation with RPZ backflow preventer
• Explore new flood mitigation devices
