2016 edition doesn't say that either. Performance information and listing limitations will be published by the manufacturer and you should seek affirmation of those metrics from them.
9.2.1.3.3* Flexible Sprinkler Hose Fittings. 9.2.1.3.3.1 Listed flexible sprinkler hose fittings and their anchoring components intended for use in installations connecting the sprinkler system piping to sprinklers shall be installed in accordance with the requirements of the listing, including any installation instructions. 9.2.3.4.4.4 Unless flexible sprinkler hose fittings in accordance with 9.2.1.3.3.1 are used, the hanger closest to the sprinkler shall be of a type that prevents upward movement of the pipe. Steve L. From: Sprinklerforum [mailto:[email protected]] On Behalf Of Mike Hairfield Sent: Thursday, October 25, 2018 8:32 AM To: Sprinkler Forum Subject: NFPA 13, 2016 Can someone send me a copy of Sections 9.2.3.4.4.4 and 9.2.1.3.3.1 please? Local AHJ is using NFPA 13,2010 and it doesn't state that Flex heads prevent upward movement when the branch line has 100 psi or greater pressure. What he is looking for is a copy of the page from NFPA 13,2016. Thanks Mike
