Backflow Prevention
Backflow prevention devices keep contaminated water from flowing back into potable water supplies. They're required by code wherever cross-connections exist, such as boiler feeds, irrigation, fire systems and process water.
Backflow Device Types
- Reduced pressure zone (RPZ) assemblies – high-hazard protection
- Double check valve assemblies – low-hazard protection
- Pressure vacuum breakers – irrigation
- Atmospheric vacuum breakers – simple point-of-use
- Repair kits and test kits – maintenance and annual testing
Choosing a Device
The hazard level and local code determine the device. Size for flow and pressure loss, and plan for annual testing access.
Centro supplies backflow prevention devices and repair kits.
