Both John and Reed are correct, however, I see the valve missing more often than not. BFP vendors do not force the issue. For years we bought our units as a tested assembly arriving in one big crate. We did pay a financial premium for this, but it is what we were taught. All designers and testers here must take and pass a 4 day "New England Water Works Association" course so at least we start out correctly.

I am looking at an existing riser with the following sequence of material: OS&Y, backflow preventer, Tee to FDC, then to 2 risers, each with control valve and alarm valve. There is no valve on the discharge of the BFP other than the aforementioned butterfly valves. Is that acceptable? It doesn't seems right but don't have any specific reference.
