Common Technical Questions

Is the Watts 0794101 compatible with the older non-lead-free 909 series?
Yes, these LFRK 909-CK2 2 1/2-3 internal components are designed to serve both the lead-free (LF909) and the original 909 series 2-1/2 inch to 3 inch backflow preventers.

Does this kit include parts for the first check valve or relief valve?
No, this specific kit is designated for the second check valve only. For a total system overhaul, you would need to source the first check and relief valve kits separately.

What are the symptoms that indicate a second check repair is necessary?
If the assembly fails the field test due to backpressure or if there is visible leakage at the second check seat—often preventing the relief valve from closing properly—it is time to install a Watts 0794101 repair kit.
