RE: [EXTERNAL] RE: FDC & Pump

[Kyle . Montgomery]

I disagree. From NFPA 13, 2016 edition:

8.17.2.4.3 For multiple systems, the fire department connection shall be 
connected between the supply control valve and the system control valves.

Wouldn’t that be on the riser manifold? The handbook even goes on to explain 
why this would be the preferable arrangement.

Am I misinterpreting this?

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:

8.17.2.4.8  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.
Thanks,
Jamie

[Prahl, Craig/GVL]

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.

RE: FDC & Pump

[Matt Grise]

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.

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