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. The assembly is listed to ASSE 1012.
- 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.
