Hey Ken, the LaSalle Bristol Cable-Actuated RV Waste Valve for Black Water Tank # 34466N4AB48GMA that you referenced is exactly what you are looking for. It is the same thing as the part number 72-4396 66N4AB48GMA you are looking for we just have slightly modified the part number. Is yours leaking?

Jason, thanks for your prompt reply. It was not leaking when I started the winterization process. It opened without difficulity. When I tried to close, it would not close with normal pressure. I finally got it closed with additional pressure. It is a fairly new valve having been replaced two years ago because of a small leak Thanks Ken Hopkins

@KenH makes sense! Yeah a new valve would fix you.
