Good morning, Is it permissible to install PVC (C900) as the spigot piece through the floor slab of a building? There would be about 6 to 8" of exposed piping. All I can find in the 2013 edition of 13 is that Fire Resistance of the Pipe shall be considered (10.1.4 (1)).
It appears that this wording has been done away with in the 2016 edition and replaced with this, "Where piping installed in a private fire service main must be installed above grade, the piping materials shall conform to NFPA 13". Based on this, it looks to me like using PVC through the floor will be acceptable moving forward. Is this correct? Thanks for the help, Bob Knight, CET III 208-318-3057 www.firebyknight.com _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org
