I’m also not seeing a supply on this graph……not sure how he got the program to work without adding a supply….its been a while since I have been on hydraCAD with I don’t remember having a graph pop up without a supply.

I usually see ‘required pressure’ as an output of the software no matter what the input is.

I have always put in a “pumper connection” supply at the FDC, did a demand calc and tweaked it until I ended up with a zero pound cushion to see what was really required. His way looks to be good. Have I been taking the hard way around to solve what PSI is required at the FDC? Thanks, Dewayne Martinez Fire Protection Design Manager TOTAL Mechanical Building Integrity W234 N2830 Paul Rd.
