The PVB includes a check valve which is designed to close with the aid of a spring when flow stops. It also has an air inlet valve which is designed to open when the internal pressure is one psi above atmospheric pressure so that no non-potable liquid may be siphoned back into the potable water system. Being spring loaded it does not rely upon gravity as does the atmospheric vacuum breaker. This assembly includes resilient seated shut-off valves and test cocks. The PVB must be installed at least twelve (12) inches above all downstream piping and outlets. The PVB may be used to protect against a pollutant or contaminant, however, it may only be used to protect against back siphonage. It is not acceptable protection against backpressure.

Glass prints. Face mounted glass print is the premium option. The image runs all the way to the edge with no border whatsoever. The ultra clear glass really makes the image 'pop'. These prints also feature concealed, easy to install mounts, giving the image the appearance of floating off the wall.

Atmospheric vacuum breakerinstallation

This is a cut-away of the atmospheric vacuum breaker, available in brass or plastic.  Look at the image and note that inside the brass casing is a plastic float with a seal.  Water under pressure pushes the float up and flows out the side fitting to the irrigation system.  If water is back siphoned water pressure closes the float seal and the water is discharged through the bell and onto the ground.  Therefore, this device must be located 12" above ground and on the downstream side of each remote control valve.

This assembly consists of two internally loaded independently operating check valves and a relief valve located between the check valves. This relief valve is designed to maintain a zone of reduced pressure between the two check valves at all times. The RP also contains tightly closing, resilient seated gate valves upstream and downstream of the check valves along with test cocks. This assembly is used for the protection of the potable water supply from either pollutants or contaminants and may be used to protect against either back siphonage or backpressure.

Since back pressure can cause the float to stick open, there can be no irrigation heads above the vacuum breaker.  In the image below, sprinkler heads are located on a slope.  If an atmospheric vacuum breaker is used, it would have to be placed at the top of the slope and 12" above the highest head.
