Watts 0072203 Valve

The Watts 0072203 is a 1/2-inch dual check valve backflow preventer engineered for reliable containment in non-health hazard residential water systems. Designed to drop into line immediately downstream of the water meter or at service entrances, this LF7RU2-2 model effectively blocks the reverse flow of polluted water caused by backsiphonage or backpressure. Featuring a lead-free bronze body for long-term durability and compliance with strict potable water standards, the valve utilizes two independent, replaceable check modules and stainless steel springs to ensure positive seating. Its compact inline design allows for flexible installation in either vertical or horizontal orientations, making it a versatile choice for tight mechanical spaces.

This unit serves as the direct 1/2-inch NPT updated replacement for discontinued Watts models 0061783, 0061785, and LF7RU2-2. Rated for a maximum working pressure of 175 psi and operating temperatures from 33°F to 180°F, it provides consistent protection under various residential flow conditions. The union female NPT inlet and female NPT outlet simplify serviceability, allowing for quick removal or module replacement without extensive repiping. By integrating this ASSE 1024 certified device, contractors ensure compliance with local plumbing codes while protecting the building's domestic water supply from cross-connection risks.

• Optimized Compatibility: Replaces legacy Watts 0061783 and 0061785 models with a standard 1/2" union connection.
• Modular Maintenance: Features replaceable check valves and silicone seat discs for fast field servicing without replacing the entire body.
• Lead-Free Reliability: Constructed from cast copper silicon alloy to meet modern safety standards for potable water connections.
• System Protection: Rated for continuous pressure applications up to 175 psi with low pressure drop characteristics.
• Installation Flexibility: Fully guided check assemblies permit vertical or horizontal mounting configurations.

Is the Watts 0072203 suitable for high-hazard commercial applications?
No, this dual check valve is specifically designed for non-health hazard residential containment. For high-hazard protection involving chemicals or toxins, a reduced pressure zone (RPZ) assembly is required.

What is the difference between this and the older 0061783?
The 0072203 is the current lead-free successor. It maintains similar dimensions but utilizes updated materials and internal modules to comply with current regulatory standards while ensuring a direct fit for the LF7RU2-2 series.

Does this valve require a thermal expansion tank?
Installing a backflow preventer creates a closed system. It is standard plumbing practice to install a thermal expansion tank on the water heater line to manage pressure increases and protect the dual check internal components.
