RE: NYC Standpipe

I would think 4" would be allowable for the shorter standpipes, but I've never worked in NYC so my thoughts probably aren't worth much. You are going to run calcs to prove that 4" would work hydraulically, right? Kyle Montgomery [cid:image001.gif@01CAA0CE.8D8066F0] Aero Automatic Sprinkler Co.

RE: NYC Standpipe

I would think the height would state size so 4" and 6". I do believe NYFD has their own FDV flow requirements, 230 gpm at 80 psi (if I remember right). TD From: Sprinklerforum [mailto:sprinklerforum-boun...@lists.firesprinkler.org] On Behalf Of Mike Stossel Sent: Tuesday, October 24, 2017
