PVB Assemblies

Pressure vacuum breaker assemblies (PVBA) are the most frequently used and inexpensive type of whole-system backflow preventer device. The benefits of this type of sprinkler backflow prevention valve are its low cost and simplicity.

PVBAs are easy to install, maintain, and repair. Some models of pressure vacuum breaker assemblies include built-in freeze protection valves; however, these valves only protect the backflow assembly itself, not the water lines.

These breakers will also occasionally eject some water, so it is important to purchase a spill-resistant backflow preventer model for indoor installation, or for any area where water spillage would create a nuisance. Air gap drains are also required when installing indoors. We carry a wide selection of PVBs from a variety of manufacturers, including Febco, Combraco, Wilkins, and Watts. Each pressure vacuum breaker works the same way; however there will be variation between manufacturers in size selection, price range, and product features and specs.
