Show the AHJ the 2013 edition (hopefully that is enough) and the following:

John -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Greg McGahan Sent: Wednesday, March 12, 2014 12:25 PM To: [email protected] Subject: Brass Pipe I have searched the forum archives..and informal interps... I have always thought that brass pipe was acceptable in sprinkler systems. In the 2013 edition of NFPA #13 it is expressly permitted in 6.3.6. I can't find any reference in the 2010 edition and the AHJ is going by 2010. Can anyone help me document that brass was or was not acceptable in 2010?
