The only other place where there is some restriction on piping material is in 8.3.4.3 where sprinklers with k factor of 4.2 can be installed on dry systems if the pipe is galvanized.
So on small orifice sprinklers it's an issue, and on Large Drops. But no issue for all other sprinklers? Hmmmmmmmmm? Craig L.

I didn't look at #13-07. If indeed the only requirement for galv in your adopted standard requires galv in large-drop systems, then despite the (obvious) conflicts Craig is sorting thru, then yes, only large drop systems are affected in a manner which the TC believes needed a requirement for galv, others don't. So from what I see before me, and I didn't open the referenced standard, unless you have LDs you don't need galvanized. Naturally it may be less to use galv than a pump if the dif in C factors helps you across the line between gravity and boost.... but in meeting the minimum consensus standard's requirements, go black and don't look back. We use galv simply because we think it is the right thing to do, and only refrain upon specific direction from whom we're contracted with- nothing to do with compliance with minimum consensus standards. Most people don't hydro at 225-265 PSI either. Naturally there's that great blurb in the specs that requires meeting requirements of the Owner's insurance carrier who remains anonymous, so you have no clue as to what those requirements might be! glc -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bob Knight Sent: Monday, May 19, 2008 12:19 PM To: [email protected] Subject: Missing George, Don't' look at what? The text in 13? 2007 is adopted in many areas including the area that I live in. So, the bottom line is 13 is the document of reference, then galvanized is not required with the exception of large drop systems. If there is another document referenced in the bid documentation because of insurance concerns or other concerns then and only then is the text of 13 trumped. As far as being penniless, it seems to me that almost every building owner I have dealt with is penniless.

The insurance requirements I refer to are NOT limited to LD's, FM, IRI, Lumbermans if memory works on Monday, all had requirements for dry systems to be galv for years. Fittings didn't need to be unless there were external considerations. glc _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum To Unsubscribe, send an email to:[EMAIL PROTECTED] (Put the word unsubscribe in the subject field) _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum To Unsubscribe, send an email to:[EMAIL PROTECTED] (Put the word unsubscribe in the subject field) _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum To Unsubscribe, send an email to:[EMAIL PROTECTED] (Put the word unsubscribe in the subject field)
