Notice to Installer — This device must not be installed indoors.
The Toro PVB (Pressure Vacuum Breaker) is designed to prevent backflow of contaminated water into the potable
water system due to back-siphoning conditions only. This device should not be installed indoors or where
backflow due to back pressure may occur. Installation of this device should conform to local building and plumb-
ing codes as they apply. Refer to the “Installation Requirements” on page 2 prior to installing this device.
Introduction
The Toro Model PVB is comprised of a positive-seating check valve, a spring-loaded vent float assembly
(located down stream of the check valve), quarter-turn ball valves on the inlet and outlet ports and test cocks
located upstream and downstream of the check valve. The vent float assembly is spring loaded to the open
2
position and will allow air to enter the system when line pressure drops to 1 PSI (.07 kg/cm ) or below, thus
preventing back-siphoning. This feature permits installation of irrigation control valves downstream of the
2
PVB. Recommended operating pressure range is 25–150 PSI (1.75–10.6 kg/cm ).
