Re: High-Rise with Secondary Water Supply

Galvanized is not considered to a potable piping per the USC guidelines. Water purveyors determine where backflows need to be per the Yellow Book (AWWA M14) and their own interpretations/requirements to it. Some are very sensitive to long runs of static lines. Some consider 8 feet to be the max be

I’d talk with the water purveyor about pipe upstream of the DDCVA. When you come to agreement follow up with mtg notes for them to initial and return. Before the DDCVA water quality is their charge. As fire reviewer I’d make sure I was a carful listener to that conversation. I’d also make pipe t

In our jurisdiction the backflow would be required where it enters the building from underground. A long run of black steel pipe is not allowed without a BFP assembly. Art Tiroly ATCO Fire Protection/Tiroly 24400 Highland Rd CLE 44143 216-621-8899 216-570-7030 cell From: Sprinkler

RE: High-Rise with Secondary Water Supply

High-Rise with Secondary Water Supply

I’m working on a high-rise that has two water supply lead-ins. One comes in adjacent to the pump room, but the secondary supply has to run 200+ feet through the building. The plan was to have the backflow preventors in the fire pump room. Am I violating any code requirements and/or good design p
