Have you guys even seen the inside of a galvanized sprinkler system
that trapped water? It is much easier to replace the pipe when it is
above grade. Wrap the pipe all you want but this pipe will rust out
from the inside if it not bone dry inside all the time. We are
pumping nice moist air into it and we do have to flow it out to some
point once a year. It won't be dug up and replaced when it fails. It
will be run visible. I think this pipe needs to be copper or DI.
Contrary to conventional wisdom, stainless can do some very
unexpected things when buried.

One other key point (I think) is that this underground pipe will be
pressurized with air - it's for a dry system.
How about going with copper?
