Pressure Vacuum Breakers
Febco’s pressure vacuum breaker assemblies (PVBA) are the most commonly used and least expensive type of whole-system backflow prevention valve. The benefits of this type of sprinkler backflow preventer are its low cost and simplicity. These assemblies are easy to install, maintain, and repair. Some models of Febco’s pressure vacuum breaker assemblies include built-in freeze protection valves; however, pressure vacuum breakers only protect the assembly itself, not the water lines.
