SKU CH-HVPM-MA8TM

  • Size3/4 in
  • ASSE 1015 certified for backflow protection
  • AWWA C-510-89 compliant for waterworks reliability
  • Bronze construction resists corrosion in potable systems
  • Quarter-turn operation allows quick manual control
  • Integrated strainer captures debris to maintain flow

Double Check Valve Assembly

The Watts 007M2QTS is a double check valve assembly designed for backflow prevention in potable water systems. It suits residential and light commercial installations where cross-connection control is required by code.

Quarter-turn 3/4 inch NPT with strainer

The bronze body measures 19 1/4 inches long by 6 7/8 inches wide and accepts 3/4 inch NPT connections. Quarter-turn shutoffs and an included strainer simplify maintenance, while ASSE 1015 and AWWA C-510-89 listings confirm compliance for standard backflow applications. It does not meet reduced-pressure-zone requirements for high-hazard services.

Inline bronze body for horizontal runs

The straight-through bronze construction fits horizontal piping with standard NPT threads and clears 19 1/4 inches of linear space. No electrical supply or special tools are needed beyond pipe wrenches. The integral strainer protects downstream components from debris, but the assembly lacks test cocks for in-line performance verification.

Questions about this item

Will the 3/4 inch NPT connections on this Watts 007M2QTS assembly thread onto my existing copper supply lines without adapters?

The assembly uses 3/4 inch NPT connections; copper lines need male NPT adapters or sweat-to-thread fittings to join directly.

How can I verify the double check valve is sealing properly after installation?

Pressurise the line and watch the test cocks; no discharge at either check valve indicates both seats are holding per ASSE 1015 test criteria.

Does the box include the strainer shown in the specifications or must I order it separately?

The strainer is included with the assembly; no separate purchase is required.
