Negative. It can still be connected to the fire pump and be a manual wet standpipe. It only becomes an automatic standpipe if/when the fire pump and water supply is sufficient for the standpipe to operate properly without the fire department providing flow/pressure through the FDC.
And, although the answer to Brian’s initial question seems kind of obvious, you might be surprised to find out how many reviewers/AHJs/etc see a fire pump on a project and immediately assume that it has to be sized for the standpipe demand (automatic standpipe). I’ve definitely gone through the “it has a fire pump, therefore it must be an automatic standpipe” dance a time or two. -Kyle M From: Anthony Johnson <mountainfirepr...@gmail.com> Sent: Thursday, June 8, 2023 8:01 AM To: Discussion list on issues relating to automatic fire sprinklers <sprinklerforum@lists.firesprinkler.org> Subject: [EXTERNAL] [Sprinklerforum] Re: Manual Wet Standpipe & Pump Yes, the answer is in your question since a manual wet standpipe requires a fire truck. If you were to connect the standpipe to the pump it would no longer be a manual wet standpipe - it would be an automatic wet standpipe.
