Watts 0794097 Repair Kit
The Watts 0794097 Repair Kit (LFRK 909-CK1) is a specialized factory replacement designed for the 1st check valve on 4-inch Watts 909 and LF909 Reduced Pressure Zone (RPZ) assemblies. As a veteran technician, you know that maintaintaining the first check is critical for preventing nuisance tripping and ensuring the assembly holds the required pressure differential. This kit is specifically for Lead-Free models but is backwards compatible with standard 909 units. The assembly features a pre-assembled check disc and spring, which prevents the accidental release of high-tension spring energy during field service. Included in the package are the disc assembly, spring, heavy-duty cover O-ring, and FDA-approved lubricant. This Watts backflow repair kit requires no special tools for installation, allowing for efficient on-site backflow preventer maintenance and minimal system downtime. Utilizing genuine 0794097 first check parts ensures that the seat alignment and spring tension meet original factory specifications for reliable potable water protection.
Key Benefits- Optimized Compatibility: Designed specifically for the 4" Watts LF909 and 909 series RPZ valves.
- Field-Service Ready: Pre-assembled spring and disc assembly eliminates the need for a spring compressor or special tools.
- Lead-Free Construction: Complies with low-lead regulations for use in potable water systems.
- Complete Restoration: Includes essential O-rings and lubricant to ensure a leak-free seal after servicing the 1st check valve.
When should I replace the 1st check versus just the rubber parts?
If the check seat is not pitted but the valve fails to maintain the 3.0 psi differential or exhibits erratic relief valve discharge, a complete 1st check repair kit is recommended to ensure the spring tension hasn't fatigued.
Will this 0794097 kit work on the 909M1 series?
Yes, it is compatible with the 4-inch 909, 909M1, and the Lead-Free LF909 variations, as the internal check dimensions remained consistent across these design iterations.
Is the seat included in this 1st check assembly?
No, this is a check valve kit for the moving internals. If the bronze or stainless steel seat is damaged, it must be ordered as a separate seat kit.
