Not all flexible sprinkler head pipe systems are listed for dry system use, but those that are can be from what I understand. I believe this scenario is the only reason they're even listed for use in a dry system. You'll need to face your branch outlets up obviously to get the return bend effect. I believe Viking's Flex Head system is listed, but you should check, there are or were 2-3 systems and most people call them all flex heads so you need to be sure the actual system you're using is listed.

Can a flex head be installed in such a manner to replace a return bend in accordance with 7.2.2 (returns bends feeding heads in which both are in a heated space on a dry system) Thanks, Greg -- Greg McGahan Living Water Fire Protection, LLC <http://www.livingwaterfp.com <http://www.livingwaterfp.com/> > 1160 McKenzie Road Cantonment, FL 32533 850-937-1850 fax 850-937-1852 _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field) _______________________________________________ Sprinklerforum mailing list [email protected] http://fireball.firesprinkler.org/mailman/listinfo/sprinklerforum For Technical Assistance, send an email to: [email protected] To Unsubscribe, send an email to:[email protected] (Put the word unsubscribe in the subject field)
