-----Original Message----- From: sprinklerforum-boun...@firesprinkler.org [mailto:sprinklerforum-boun...@firesprinkler.org] On Behalf Of Fox Duane T. (FireMarshal) Sent: Monday, December 03, 2012 9:01 AM To: 'sprinklerforum@firesprinkler.org' Subject: 13R underground Can the underground for a 13R run under the building? The 2007 edition applies and has nothing about underground. I was under the impression that issues not covered in 13R reverted back to NFPA 13 (by reference in Chap 2). The project in question has an underground running under the slab across a dwelling unit. I looked at the 2010 edition and there is a section (5.3) that does address underground that has an Annex section that muddies the waters about my question. The Annex states that pipe 4" and above has to meet NFPA 24 (although not referenced in Chap 2) and pipe less than 4" does not have to use NFPA 24. Section 5.3 states any pipe type is acceptable but does not really discuss how it is to be laid or where it can't be laid.
