SMALL ORIFICE DRY SYSTEMS ALSO REQUIRE GALV PIPE! In 2007 13-8.3.4.3 Personally why use anything else? As handbook say's "internal pipe scale and foreign material prevalent in dry pipe and preaction systems"
[EMAIL PROTECTED] On Behalf Of George Church Didn't, not Don't. 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. _______________________________________________ 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)
