If there is no water coming through the backflow due to an interruption from the municipal source, hooking to a hydrant downstream of the backflow will not give them any water.
Is this kind of what you're talking about, source is from the left through the block(BFP) then tee to the riser and sprinkler/standpipe with straight through the tee to the hydrants. Craig L.

Deal is this: Source to backflow with FDC, 6" continues to tee that feeds standpipe and sprinkler, from the tee 6" continues to 2 fire hydrants. When FD connects to hydrant they will connect back to fdc with the sprinkler main in between the 2. Will this create a useless loop or will it work?
