Charles,
I think only FM had the requirement for galvanized pipe on dry
systems. Everybody else suggested it as a good idea. Of course, it
does give you a hydraulic advantage and I always recommend it for
outdoor installation, especially in coastal areas for durability reasons.

Hello sprinklerforum,
I think I am missing something. IF my old brain remembers it was
a requirement for dry pipe systems to use Galvanized Pipe, But were
allowed to use black iron fittings. I am unable to find that in the
2007 edition of 13, Am I dreaming, or was it deleted, or where is it now?
