Hi all,
Haven't gotten around to order it yet. I was wondering if a pressure vacuum breaker would work even better. Don't know to much of a difference between the two but I read in a place that they are better. From the place I was looking at buying it from this was there description of it.
2" Buckner Brass PVB
New 2" PVB backflow preventor.
Description
2" female pipe thread inlet and outlet
Use in constant pressure systems to prevent backflow
Atmospheric backflow prevention
5 psi loss at 120 GPM
Bronze body for durability
The PVB is designed to be installed to provide protection against backsiphonage of toxic or non-toxic liquids. It consists of a spring loaded check valve which closes when the pressure in the assembly drops below 1 PSI or when zero flow occurs, pls an air relief valve that opens to break a siphon when the pressure in the assembly drops to 1 PSI.
Typical applications are to protect against health hazzard and non-health hazzard backsiphonage conditions in industrial plants, cooling towers, laboratories, laundries, swimming pools, and lawn sprinkler systems.
Thanks as always
