I can't remember when we started, but NEWWA (and USC) (and our local purveyors) were adamant about both valves being part of the "assembly". Position was critical too as no vertical mounts could be found. Only "N" style.

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!) Cliff Whitfield, SET President Fire Design, Inc.

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.
