Backflow Protection

The proper backflow protection is so vital to your family's health.  Here is how the state defines a situation requiring protection. "Any Irrigation system connected to a potable water source shall be protected against backflow by a backflow device."

   In the State of New Jersey there are only two (2) acceptable devices.  Both of them are used for different applications. One is a Pressure Vacuum Breaker (PVB) and the other is a Reduced Pressure Vacuum Breaker (RPVB). A PVB is installed when the device calls for an installation where the device can be installed twelve (12) inches above the highest sprinkler head. The RPVB is to be used when the device is less than twelve (12) inches above the highest sprinkler head along with some installation restrictions. The majority of installations require the PVB, and is the standard of the industry.

Pressure Vacuum Breaker (Brass)

Other than those two (2) types, all others do not protect you from a backflow application. Here are the types that are unacceptable and  illegal in the State of New Jersey.

AVB (Atmospheric Vacuum Breaker)

MasterValve AVB (Valved Atmospheric Vacuum Breaker)

Master Valve (Simple Zone Valve Connected to Controller)

Double Check Valve (Dual Checkvalve assembly)
