What valve are you referring to as “standpipe feed” control?  Are you talking 
about the isolation valves required in 6.3.2?   If that’s the valve you’re 
referring to, then no you do not have to pump downstream of that (those) 

The foregoing is my opinion only and is not intended to represent the NFPA 14 
Technical Committee, nor serve as an interpretation of the standard.

Are you saying that if I put a control valve for the standpipe feed at the 
riser manifold and the FDC is connected to the riser manifold that I must also 
connect the FDC downstream of the standpipe feed control valve?  Is that in 14? 
 I have had a couple of AHJ’s make me put a control valve in over the years and 
I didn’t know it was wrong.  I thought it was just like the individual system 
control valves on the manifold.
Thank you,

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.

The requirement is from NFPA 13, not from NFPA 20. Here is the text from NFPA 
13-2013:  Fire department connections shall not be connected on the suction 
side of fire pumps.

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.
