Common Questions

What hazard level is this PVB approved for?

It is rated for high health hazard (toxic) cross-connections, but only against backsiphonage. The assembly is listed to ASSE 1020.

Does this assembly have to be tested every year?

Yes. This is a field-testable assembly. Most water authorities require it to be tested and certified by a licensed backflow tester at installation and annually thereafter. It carries USC FCCCHR approval, which many jurisdictions accept as their sole approval list.

Will this protect against backpressure?

No. A pressure vacuum breaker protects against backsiphonage only. It will not stop backflow caused by backpressure -- a downstream pump, elevated piping or a boiler -- which requires a double check or RPZ assembly instead.

How does this have to be installed?

It must be installed vertically (upright), above the highest downstream outlet, per its installation instructions and ASSE listing.
