Watts 0794071 Repair Kit
Maintain the integrity of your containment system with the Watts 0794071 (LFRK 909M1-T), a professional-grade total repair kit engineered specifically for 1-1/4 inch to 2 inch LF909 and 909M1 Series reduced pressure zone (RPZ) backflow preventers. This comprehensive genuine Watts replacement part set is designed for field service technicians who demand precision-matched components to resolve common discharge issues such as "nuisance spitting" or continuous relief valve dripping. The kit features lead-free construction and includes all wetted internal components: first and second check valve poppets, check seats, heavy-duty springs, and a complete relief valve stem assembly with high-grade diaphragms. Utilizing these original manufacturer repair parts ensures that the assembly maintains its ASSE 1013 compliance and operational pressure differential. The inclusion of high-performance lubricant and essential O-rings facilitates a seamless rebuild of the internal check modules and the relief valve sensing line without requiring specialized proprietary tools.
Key Benefits for the Contractor:- Full System Overhaul: Includes all necessary first and second check assemblies and a total relief valve kit to minimize downtime on-site.
- Optimized Performance: Resolves fluctuating supply pressure symptoms and fouled check valve issues that lead to system failure.
- Lead-Free Compliance: All components meet stringent potable water safety standards, ensuring compatibility with modern lead-free bronze bodies.
- Durable Construction: Features stainless steel and high-quality elastomers designed to withstand aggressive water conditions and thermal expansion.
- Field-Service Ready: Pre-assembled poppets and original factory O-rings ensure a precise fit and reliable backflow preventer maintenance.
What are the signs that my LF909 unit requires a total repair kit rather than just rubber parts?
If the assembly drips continually from the vent even after cleaning the discs, or if the check valve seats show signs of scale buildup or pitting, a total repair kit like the 0794071 is required. This replaces the hard seats and springs, restoring the 12-pound pressure threshold required for proper function.
Is the Watts 0794071 compatible with the older 909 models?
Yes, this 0794071 repair kit is backward compatible with the standard 909 and 909M1 series within the 1-1/4" to 2" size range. It is specifically balanced to handle the spring tension and flow characteristics of these larger diameter assemblies.
Does this kit include the air gap fitting?
No, this is an internal service repair kit. If your relief valve is discharging water and you need to direct it to a floor drain, an external Watts air gap (909AG) must be purchased separately.
