Thanks, Todd & Craig. Not to be the Devil's advocate, but section 9.3 applies to systems being protected against earthquake damage (not always the case). Would seem like good engineering (opps, I mean Layout Technicianing) to provide the coupling regardless.
Ed Kramer Littleton, CO >>Yes there is. In 2002 edition it's in section 9.3.2.3(4). Generally >>the use of a non-rigid style grooved coupling allows enough deflection >>for these types of expansion joints and is acceptable to most AHJ's. _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum
