That would show whether it was needed or not. It wouldn't show = to code requiring flow of two more heads, which would provide better protection even if they weren't needed.
Not saying it won't work, saying it isn't equal to #13. George L. Church, Jr., CET Rowe Sprinkler Systems, Inc.

Same thing Bill Brooks pointed out on larger SF/system, although I'd rather write something on that, maybe lessening # of valves = less chance one is shut. When all you do is omit flow cause the other guy says you can, where's the = or better? George L. Church, Jr., CET Rowe Sprinkler Systems, Inc.

Does the ROP/ROC for 2013 NFPA #13 contain any proposals to drop the requirement to calc an additional 2 heads under obstructions below ESFR systems as FMG has done?
