NFPA 25 2014 Edition, section 13.6.2.1 I have a 6” Ames 2000 SS that I need to forward flow test. Down stream of the #2 OS&Y control valve I have a 6” elbow, a 12” section of 6” pipe on the vertical, Then a 6x6x4 tee (4” to the FDC), then on top if the Tee a 6 “ dry valve. 13.6.2.1 says we shall exercise annually at minimum flow rate of the system demand. But guess what. There is not a Hydraulic nameplate. It would be easy to flip the FDC check valve and flow out thru the FDC siamese connection, but not if it will not meet the system demand. My question is, without the owner providing what that demand is, how do I know if the 4” FDC method will be enough? Or do I remove the 6” elbow and install a tee and some fittings and pipe to flow the full 6” out the door which is about 6’ away.
