Maybe I did not fully get the "flows always end at a given tip" rule - doesn't R7C9 violate this constraint?

22:01 to solve this one. Definitely not my slowest solve of one of your slow thermo puzzles… maybe I’m just getting better at them? This one was beautiful, thanks!

15 minutes, not so tricky.... when there is beautiful logic and no ambiguous valve that's not so complicated
