Deluge Valve Release System

Question asked by rperkin9 on Jul 23, 2019

Does anyone know the pressure testing requirements for hydraulic release lines (wet pilot) and Pneumatic release lines (dry pilot) attached to a deluge valve? I can only find that piping exposed to system working pressure required the standard pressure test from chapter 25 of NFPA 13. However dry pilot lines are not exposed to system working pressure.
