That is the way we would design it. This is an architect/engineer design/requirement. I guess you could look at the standpipes as being in parallel to each other and not in series. Would this only increase the volume and not the pressure? Maybe I am over thinking this.

Wouldn't it be better and easiest if FDC(s) were common to all piping downstream of the pump? Steve Jay White <jwh...@dynamicfirepro.com> wrote: Good morning. We are looking at a large structure that has four standpipes installed. All standpipes are connected and being fed from a fire pump. Each standpipe will have its own FDC as well as the fire pump. In a fire scenario, if the fire department connects to more than one FDC is there a chance that the system could be over pressurized (more than 175 psi) and how is this avoided? Is it up to the fire department to recognize the pressure is exceeding the system limitations and back off the pressure?
