Common Questions
- What hazard level is this Double 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 1015.
- 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.
- Does this assembly have to be tested every year?
- Yes. This is a field-testable assembly with 4 test cocks. 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.
- What shutoff valves are included?
- It is supplied with quarter-turn ball valves on the inlet and outlet.
- 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.
