Jeff, I think I started off with a rail sweep with draft angle for the tapered water jet and I made the profile square with radius on the corners and then added twist to the rail sweep also. I used a glass material and not sure now if I used plain coverage or eroded. It looks all right from a distance but not so good close up.
I am on my notebook at present but will check the proper settings later when I am on my desktop machine.
It would work Jeff, it just becomes a static header much like a hose with a knot in. The open line tees off into a water supply.
