What do you mean by "is no longer the case"? It works for me.
I think Jesse just pointed me to the issue. The line between the wet well and the pump is flowing full and therefore should be pressure pipe not a gravity conduit. Try that.
In terms of why you need to do it that way with the Convex solver when you can use a conduit with the Implicit solver: please see the below solution wiki:

Regarding the virtual link - do a search for "virtual" in the included help documentation and you'll find a few sections that discuss this in detail. Basically a virtual pipe has no hydraulic significance to the network and simply passes the upstream flow to the downstream node. It's useful for situations such as submersible pumps where there is no pipe between the pump and the wetwell.
Hope this helps,

Thanks Jesse and Tom -
I did get it to work by morphing and will check the wiki, I guess I used the wrong term to search. Thanks for pointing it to me.
As for virtual link, I will definitely look a little closer as I don't understand that there is not a significant importance. Discharge assemblies on pumps do have typically unions, check valves, flex tubing, 90s, etc. so before I open my mouth and put my foot in it I will do some research.
Thanks for the help!
