Watts 0072204 Valve

The Watts 0072204 (Model LF7RU2-2) is a high-performance 3/4 inch dual check backflow preventer engineered specifically for residential containment and continuous pressure applications. As the direct lead-free replacement for legacy models 0061791, 61783, and LF7RU2-2-3/4, this valve features a robust copper silicon alloy body and stainless steel springs to ensure long-term reliability in non-health hazard potable water systems. Designed for installation immediately downstream of the residential water meter, it utilizes two compact, replaceable plastic check modules that facilitate easy in-line maintenance without removing the entire assembly. This unit supports a maximum working pressure of 175 psi and an operating temperature range of 33°F to 180°F, making it a standard choice for contractors managing backflow prevention at the service entrance. The 3/4" Union FNPT x FNPT connection allows for simplified installation in either vertical or horizontal orientations while maintaining a low pressure drop of approximately 5 psi at 15 GPM.

• Direct Compatibility: Seamlessly replaces discontinued 7-3/4 and 0061791 units, ensuring the 7-3/4 inch installation length is maintained for existing piping layouts.
• Maintenance Efficiency: Features replaceable check modules and a union inlet, allowing technicians to service internal components rapidly and reduce labor time.
• Lead-Free Reliability: Fully compliant with Safe Drinking Water Act requirements using a lead-free brass construction that resists dezincification and corrosion.
• Versatile Installation: Verified for both vertical and horizontal mounting, providing flexibility in tight mechanical rooms or meter pits.
• Industry Certification: Meets ASSE 1024, CSA B64.6, and NSF/ANSI 61-G standards for residential water system containment.

Is the Watts 0072204 a direct replacement for my older 1/2" or 3/4" Series 7 valve?
Yes, the 0072204 is designed to replace the LF7RU2-2 and older 7 series variants. If your existing valve has a union nut and an approximate 3-5/8" body length (excluding union tails), this is the current technical standard for that footprint.

Does this valve require a specific orientation?
Technically, it can be installed horizontally or vertically. However, seasoned technicians recommend ensuring the flow arrow on the cast bronze body matches the supply direction and maintaining at least 12 inches of clearance for future maintenance access.

Will this prevent thermal expansion issues?
While this dual check valve prevents backflow into the municipal supply, it creates a closed system. You must ensure a thermal expansion tank is installed on the water heater side to prevent over-pressurization and relief valve weeping.
