If I've got a large schematic area of, say, 300 gpm, and I want to break it up into 6 50gpm chunks, shouldn't each valve I pipe to the area show it's relative portion of that area (in the call-out), with appropriate pipe size? IOW, 6 valves, 6 call-outs showing 50gpm, and the appropriate pipe size? My current project is not doing that.
I have placed several valves into big schematic drip areas. The problem is that those valves are not splitting flows as they should do automatically - they are multiplying the same flow, so instead of having 4 zones with flow 80l/min (total 320 l/min), I end up with 4 zones with 320l/min flow. Moreover, this is making the mainline sizing impossible as I do not have a water source supporting this flow.
