|
|
|
|
 | A Pressure Vacuum Breaker Assembly (P.V.B.) protects against backsiphonage only, and are ineffective against backpressure. Being spring loaded they can be installed on the pressure side of a shutoff valve. They must be installed 12" above all downstream piping and sprinkler heads. This backflow prevention assembly is used to protect against pollutants or contaminants. | | Click on Image for Larger View | | The PVB should be installed as follows: - The assembly is not to be installed in a pit or in a location where any part of the assembly could become submerged in standing water.
- Install upstream of the sprinkler zone valves
- Install a minimum of 12 inches above the highest outlet it serves.
- Protect the assembly from freezing by properly draining it in the winter months when the system is not in use.
- Install in an accessible location for servicing and inspection "which is to be done yearly by a state certified tester."
