Customer wants a small anti-freeze system on a loading dock. The existing system is a steel pipe system with a double check backflow at the service entry. Normally I would just tap into the closest main (5 feet away), drop down to a reduced pressure backflow and install an expansion tank and the eight head anti-freeze system. The water purveyor now tells me that is unacceptable. They want the anti-freeze system tied into the ductile iron pipe at the service entrance, before the existing double check, and fed with non ferrous pipe. They say they do not want any type of backflow device fed with black steel pipe. This, I believe, is not a code issue. Has anyone run into this situation before?
