>From NFPA 25 2011: 3.3.7.2 Sectional Drain. A drain lo cated beyond a sectional control valve that drains only a portion of the system (e.g., a drain located beyond a floor control valve on a multistory building). Interestingly there is a conflicting entry in NFPA 13 2010 that probably should be addressed if this is the way we're going (not requiring full flow main drain tests @ floor controls): 8.17.3.1 A pressure gauge with a connection not smaller than 1/4 in. (6 mm) shall be installed at the system main drain, at each main drain associated with a floor control valve, and on the inlet and outlet side of each pressure-reducing valve.
