Ron I missed the part in Bobs post about the butterfly valves. When we have done this we used a Wilkins 350ADA with a Post Indicator valve, which is on the approved list, the water guys over here are trained by the water guys over there so they are no easier to deal with. I did not see that Bob was proposing a PI valve in addition to the Backflow preventer.

Happy about it, but surprised. This side of the hills that wouldn't happen as the "listing" would void if you change the valve type/style that comes with the assembly. I even asked USC about this as the only difference between OS&Y, NRS, & PIV is the operating mechanism. They said no. Maybe something has changed.
