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 substance downstream could be a health hazard, codes require a reduced pressure zone (RPZ) assembly instead.

Can this be installed on potable water?

No. This model is not certified lead-free, so it may not be installed in potable water systems in states enforcing the NSF/ANSI 372 weighted-average lead rule. Use it on non-potable service — fire lines, irrigation or industrial water — or order the LF (lead-free) version of this model for drinking-water use.

Can this device be field tested?

No. It has no test cocks and 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.

How does this have to be installed?

It is approved for either horizontal or vertical installation, with the flow arrow on the body pointing in the direction of flow.
