Lets not lose sight that the question was about extending above ground system

Using nitrogen should help mitigate the corrosion issue with standard DI.
I assume there will be a drum-drip back in the riser room so they can

Thanks Craig. Yes, the valve room is below grade.
If we use nitrogen to charge the dry system then would we just use standard DI?
