I disagree. From NFPA 13, 2016 edition: 8.17.2.4.3 For multiple systems, the fire department connection shall be connected between the supply control valve and the system control valves.
Wouldn’t that be on the riser manifold? The handbook even goes on to explain why this would be the preferable arrangement. Am I misinterpreting this? -Kyle M From: Sprinklerforum [mailto:sprinklerforum-boun...@lists.firesprinkler.org] On Behalf Of Tom Duross Sent: Wednesday, January 31, 2018 3:36 PM To: sprinklerforum@lists.firesprinkler.org Subject: [EXTERNAL] RE: FDC & Pump What Larry said.. And there can’t be any valves between the FDC and the FDV’s on the standpipe unless you have more than one standpipe and have isolation valves at the base of each standpipe so you can’t take them off the riser manifold, for example. TD The requirement is from NFPA 13, not from NFPA 20. Here is the text from NFPA 13-2013: 8.17.2.4.8 Fire department connections shall not be connected on the suction side of fire pumps. Larry Keeping I have always installed FDC's on the discharge side of fire pumps. Looking through 2013 NFPA 20, I don't see anything precluding the instillation on the supply side. Is the FDC allowed to be installed on the supply? I have a contractor that has installed the FDC on the supply run-in, instead of stubing up a secondary line from the remote FDC. Thanks, Jamie
