I think it depends on how old the BFP is. Back in the mid 80's when we first began to install these, we could buy them without valves and install them as mentioned. At that time, there was no issue with the listing (as much as I can remember that far back!)

Unless it was furnished by the manufacturer less valves. But my understanding is they can't do that because there's no way to test it according to the USC method for certification.

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.
