So... Remembering how a durso works and reviewing my original bean design and combining it with my idea of an actuated valve.....
Maybe, instead of a passive system that depends on a calibrated air valve (durso steady state), or a high water level response siphon (bean's bent airline to above the waterline), I use a dedicated vacuum pump that is initiated when the surge valves turn on to create a water-full chamber in the pipe?
If it works, the few seconds lead it has could initiate a full siphon (or a few of them) just as the surge raises the water level! I'll model it out first.
See? This is innovation inspired by collaboration... Maybe
