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?
