Watts 0391007 Backflow Preventer

The Watts 0391007 009M2QT 2" Backflow Preventer is a professional-grade reduced pressure zone assembly designed to protect potable water supplies by preventing backsiphonage and backpressure in high-hazard applications. This unit serves as the direct replacement and update for the legacy Watts 0063010, featuring a compact, bronze body construction that simplifies installation in tight mechanical rooms. The Watts 009 Series utilizes a modular design with two independent check valves and a pressure differential relief valve located between them. This 2 inch RPZ valve is rated for working pressures up to 175 psi and fluid temperatures from 33°F to 180°F. Contractors prioritize this model for its 009M2QT lead free compliance and the inclusion of two full-port, resilient seated threaded quarter-turn ball valve shutoffs. The single cover design and replaceable seats ensure streamlined field maintenance and testing without removing the assembly from the line.

Common Questions

How do I troubleshoot a constantly leaking relief valve?
Usually, a discharge from the relief valve indicates either dirt/debris on the first check valve seat or a significant pressure drop in the supply line. Inspect the first check assembly for fouling before replacing internal components.

Is the 009M2QT suitable for vertical installation?
Yes, the Watts 0391007 is designed for both horizontal and vertical "up" flow orientations, provided the relief valve remains accessible for testing and drainage.

Does this unit meet current lead-free regulations?
This specific potable water backflow preventer is manufactured to meet all current Lead Free requirements for plumbing applications in high-hazard environments.
