Watts 0063231 Valve

The Watts 0063231, also identified as the LF007M3-QT-3/4, is a high-performance 3/4 inch double check valve backflow preventer engineered for non-health hazard cross-connections. This field-proven assembly features a lead-free cast copper silicon alloy body designed to prevent backsiphonage and backpressure of polluted water into the potable water system. Primarily utilized in continuous pressure commercial and residential applications, it incorporates two independent, positive-seating check modules. Contractors value the modular design, which allows for in-line servicing via a single access cover without the need for specialized tools. With a maximum working pressure of 175 psi and a temperature range of 33°F to 180°F, this unit ensures reliable protection in diverse environments. The assembly includes quarter-turn ball valve shutoffs and top-mounted test cocks for simplified diagnostic testing. This model is a direct lead-free replacement for legacy 007M3-QT bronze assemblies, meeting ASSE 1015 and AWWA C510 compliance standards for potable water safety.

• Modular Top-Entry Design: Facilitates rapid maintenance and replaceable seats/discs without removing the unit from the line.
• Enhanced Flow Characteristics: Engineered for minimal pressure drop across the internal check modules.
• Lead-Free Construction: Complies with current federal safety regulations for potable water distribution.
• Integrated Test Cocks: Top-mounted resilient seated ball valve test cocks allow for easy annual performance verification.
• Compact Housing: Reduced footprint for tight mechanical room installations or irrigation enclosures.

Is the Watts 0063231 compatible with vertical installations?
Yes, the LF007M3-QT can be installed in both horizontal and vertical "up-flow" orientations, though you must verify local plumbing code approvals for your specific jurisdiction.

How does this model differ from the standard 007M3-QT?
The 0063231 is the lead-free backflow preventer version (LF), whereas the standard 007M3 is the non-lead-free bronze legacy model. They share identical physical dimensions (11-1/8 inches in length) for high-compatibility retrofitting.

What is the typical pressure loss for this 3/4" assembly?
Technicians can typically expect a pressure drop between 8 and 15 psi depending on the flow rate (GPM) and supply pressure.
