Both of these standpipes are being planned as feeds for the fire sprinkler system.In other words, at each level the fire sprinkler system will tap off each standpipe so that it can be looped at each floor. I had someone tell me that this was against code and that you could tap off each standpipe but they could not be connected (ie. looped). When I questioned which code states this they didn't have an answer. I have never come across a code stating this could not be done - afterall, loops are legitimate system types defined in NFPA #13. In the past we would put a sign at each control valve stating that each floor is controlled by two control valves at each stairwell and everyone was alright with this. Has anyone ever heard of such a code? Thanks, -B- --------------------------------- Never miss a thing.
