The pump will still boost its inlet pressure. If you use the FDC to boost the
inlet pressure to 175, then the pump will discharge 175 + pump pressure. Could
be too much.

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
Thanks everyone. I knew why, I just couldn't remember where.

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,
Last time I looked the FDC was not allowed on the suction side. That
requirement was in NFPA 13 under the FDC location section.

The FDC is for pressurizing the loop in the event that the main fire pump is
out of service and you have to use the pumper apparatus.

I disagree. From NFPA 13, 2016 edition:

Wouldn’t that be on the riser manifold? The handbook even goes on to explain
