I have decided to just calc 1500 sf with a C-factor of 100. It's a small system so it won't be a huge impact. Thanks for your help. Thank you, Bob Knight, CET III Fire by Knight, LLC 208-318-3057 From: Sprinklerforum [mailto:sprinklerforum-boun...@lists.firesprinkl

One of the biggest impacts is that calculating as a dry system means you have to increase remote area size by 30%, but you don't have to do that if you can calculate as wet. -Kyle M From: Sprinklerforum [mailto:sprinklerforum-boun...@lists.firesprinkler.org] On Behalf Of Bob Knight Sent

RE: recommended pre-action system

Looking at this, it states, "It is the intent of this design/utilization to satisfy the requirements of all piping systems including CPVC". Do any of you know is this valve listed for use with CPVC? It's listed for 13D & 13R, but I didn't find anything specific to CPVC other then the note above.

That's a good question Todd. I've always assumed rated flow even though many, as you mention, do show the max flow. I didn't read this nor was I told to do it that way, I just always have. This will be good info when we get the answer. Bob -Original Message- From: sprinklerforum-boun
