allowance. So what I am gathering for these posts is that I should have accounted for 104000 gpm? Even at the number of buildings we actually did it would have been 5200gpm. I'm sorry but this really sounds way off and definitely not covered by 13R. Thanks, Eric Tysinger CET NICET 108988 Des

RE: NFPA 13R/D and ceiling pockets
