Joe,
Filling the system with nitrogen prior to filling with water would permit
"sparging" of the N2 with the H2O. You could very well leave 14 psi of
nitrogen on the CPVC system prior to filling with water. This would achieve an
added protective for your metal piping.
But, you may want to
Good question. Sorry, thoughts on applying it to CPVC.

Are you seeking thoughts on applying it to CPVC or thoughts on the practice of
Nitrogen inerting wet systems?

But seriously folks... I wouldn't take my (or Cecil's, no offense) opinion
for more than you're paying for it with regard to CPVC compatibility. Reach
out to Lubrizol or Spears, highest level tech support you can connect with.

I am not following the question of “how”…
Could you just use 15psi of supervisory nitrogen for the entire system?

I am looking for thoughts on nitrogen corrosion for a wet system that has
both CPVC and steel pipes. 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?
Best
