Common Questions

What hazard level is this Dual Check approved for?

It is rated for low health hazard (non-toxic, "pollutant") cross-connections only. Where the downstream substance could be a health hazard, codes require a reduced pressure zone (RPZ) assembly or a detector assembly instead.

Is this model legal for potable water?

Yes. It is certified lead-free to NSF/ANSI 372, which is what state plumbing codes require for any device in a drinking-water line.

Can this device be field tested?

No. It is not a testable assembly, so it cannot be certified by a backflow tester. Where a jurisdiction requires an annually tested device, specify a testable assembly (double check, RPZ, or PVB) instead.

Is this listed for fire protection service?

Yes -- it is FM Approved, the listings normally required for a backflow device on a fire sprinkler supply.
