And predictably my answer was incomplete as you offered two options and I blipped over that. What I said but also what Travis said.

Steve Leyton Protection Design & Consulting San Diego, CA From: Sprinklerforum [mailto:[email protected]] On Behalf Of Dewayne Martinez Sent: Wednesday, September 19, 2018 12:09 PM To: [email protected] Cc: Dewayne Martinez Subject: multi-height standpipes I have a high rise which contains 3 standpipes. Two of them go up 25 stories and the third only 4 stories. When I calculate them do I pick up 2@ 250gpm on the most remote high standpipe followed by 250 on the remaining stairwells including the low one or just the two high ones? To complicate the matter even more the high standpipes would not have a pressure reducing hose valves in the calculation but the low standpipe would need one.
