The Watts 007M1-QT-CT-FZ 2 is a 2" double check valve assembly with NPT connections, approved for low health hazard protection. It features a bronze body and a rubber seat. Rated to 175 psi and 33°F to 180°F.
This 2 inch double check valve backflow preventer assembly is designed to prevent the backflow of polluted water from entering into the potable water supply due to backsiphonage and or backpressure in accordance with national plumbing codes and water authority requirements. Its compact modular design facilitates easy maintenance with a single access cover for in-line repairs. It is ideal for protection in continuous pressure piping applications and at cross-connections identified as non-health hazards and for contaminants at the service line entrance. This assembly consists of a cast bronze body construction, NPT end connections, quarter turn ball valve shutoffs, cap and tether top mounted test cocks, two in-line independent positive seating check modules, captured springs, and replaceable check discs and seats. The double check valve includes a freeze sensor for use with SentryPlus Alert® technology to signal facility personnel when temperature nears and reaches the freezing point. Freeze alerts feature available with add-on connection kit for Wi-Fi networks, building management systems (BMS), irrigation management systems (IMS).

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 substance downstream could be a health hazard, codes require a reduced pressure zone (RPZ) assembly instead. The assembly is listed to ASSE 1015.
- 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.
- 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.
- Is this listed for fire protection service?
- Yes — it is UL Classified, the listings normally required for a backflow device on a fire sprinkler supply.
