The Above-Ground Backflow Preventer Vault (RPZ) protects against elements and cross-connection contamination.

More severe cross-connection hazards may require a special type of backflow preventer that can automatically discharge potentially polluted water before it enters the public water supply. Since they must be installed above ground, Reduced Pressure Zone (RPZ) assemblies are furnished in turn-key aluminum enclosures that provide protection against vandalism and freezing. Available in various colors.
