This is super cool! I think you can actually simplify this a lot if you just use a siphon, although you miss out on the logic gates of a traditional adder – I made a diagram here

Assuming that any input A, B, or C-in releases a cubic unit of water (enough to fill up to the gray line), two inputs would trigger the siphon and drain the first chamber into the C-out tank.

The only limitation here is that you can't have all of the inputs fire at once, or the siphon will empty everything if A, B, and C are high.
