In 8.16.4.2.3 it talks about protecting piping exposed to weather. It doesn't matter if it's wet, PA or whatever. You don't have to use galv. in PA systems. Although some EOR's may require it for longevity or because it is a client or Underwriter requirement. Craig L.

Is there somewhere it states the pipe and fittings are to be corrosion resistant (ex. Galv.)? I thought somewhere it stated for preact it had to be regardless, but I can't find that either. Maybe I'm pulling an old spec from a project out of my brain as the last two I've done have required galv. piping per the spec book. Bobby Gillett Sr. Project Manager Key Fire Protection, Inc.
