I'm looking at an FDC setup on the underground main to a building

Thanks Bob, I see it now. Its been added for 2010 14. The latest IBC we use
is 2009. It references 2007 14 and it makes statements as if it
is coordinated with 2007 14. Maybe the latest IBC has changed its tune.

by manufacturer and sprinkler type but you can get a general idea of what

sch 10 losses per foot are smaller than sch 40 losses per foot. So its going

It is the intersection between the gpm/pd water supply curve at the pipe

My thoughts are the same regarding the reason but when you choose to live by
the sword you also must die by the sword and the rule says pipe nipple
without mentioning fitting. There is even a sketch. The fitting in question
