What is the minimum and maximum diameter that waterCAD allows to use to model a network. I mean theoretical diameters without considering commercial diameters
There is no any theoretical minimum and maximum pipe diameter limit in WaterCAD, you can model pipes of any size and WaterCAD will design your system for pressure, velocity, headloss based on that.
You can try that yourself, prepare different scenarios for different diameters and see the results and compare for a better solution.
