Ah… right! So is the goal to nitrogen purge when the system is drained? Matt

So, no, I don’t think that’s an option. But Cecil’s suggestion of using nitrogen to purge the atmospheric air from the system and then bleeding off the nitrogen as you fill the system with water seems like a reasonable way to do it. -Kyle M From: Matt Grise <m...@afpsprink.com<mailto:m...@afpsprink.com>> Sent: Thursday, April 21, 2022 9:04 AM To: sprinklerforum@lists.firesprinkler.org<mailto:sprinklerforum@lists.firesprinkler.org> Subject: [EXTERNAL] [Sprinklerforum] Re: Nitrogen and CPVC I am not following the question of “how”… Could you just use 15psi of supervisory nitrogen for the entire system?

I read most manufacturers only allow air or nitrogen at no more than 15 PSI for pre-testing only. So I am wondering how nitrogen pressure can be used at all when you have a wet CPVC system?
