Okay. So I just got another piece of information that is pretty important. The flood cycle is supposed to be 1:3 ratio to the drain cycle.

IF that rule of thumb is accurate, then simply reducing each of the 1/4 turn valves, and leaving the drain line plumbing intact where it is should work just fine. Then once it's at least cycling properly then I can increase/decrease the valves as needed following the above rule of thumb.

And further research in other forums, seems to support JCO's comment above. Tomorrow is going to be interesting as I exercise some trial and error.
