How would you shut down potential supply flow from the common FDC to the out of service system riser?

Each system riser would need its own FDC check valve. Doing this might require more bulk pipe and a couple more control valves. Ed Kramer Bamford Fire From: Sprinklerforum [mailto:[email protected]] On Behalf Of Brian Harris Sent: Monday, February 06, 2017 9:31 AM To: [email protected]<mailto:[email protected]> Subject: (1) FDC or (2) I'm working on a storage building that because of the way the building was built each "side" has its own Riser with its own FDC connection (picture a big horseshoe shape). The architect has requested that a single FDC be located on the corner of one of the building sides. Is it feasible to do this and tie the systems together via the FDC pipe or does each Riser still require its own FDC connection? Brian Harris, CET BVS Systems Inc.
