I have a minor issue on a new project. I have piped all of the lateral lines and mainline, and sized all the lateral pipe. When i try to size the mainline, it gives me an error message with the critical zone, that i have exceeded 5fps and then 3fps. So when i look at this valve and highlight it, it shows somewhere between 10-11 gpm, when i size it, it reads 15.8 gpm. Any ideas what might be causing this?

Craig,

 

It looks like the Sizing is double-counting the GPM of one of the areas.  You can find out which one by using the Edit Equipment button and selecting segments of pipe.

The cause is undoubtedly a polyline area that has overlapping or circular points, so it is unable to correctly count how many pipe end points are within the area.  The solution would be to redraw that boundary.
