I ran something similar to your design in my last house. I ran a herby and ran 3 x 1.5" lines with flex PVC. I flowed it with a hammerhead pinched way back. My vertical was about 8' and horizontal maybe 10-12 '. I used the flex as it was easier to snake up the finished ceiling/walls. My gate valve for the herby was at the tank (less weight on lines). Seemed to work fine, the drain was pinched back a ways, probably could have gotten away with 1" but I figured why not go larger to guarantee I had enough drain size.
That what worked in my situation.
