I designed a similar system a few years back when I was working on my automation system. I just posted a shematic in another thread....CLICK HERE
The design is similar but also takes into consideration sump "overlfow" levels and sump "dry" conditions.
If the sump overfils, the topoff power is removed. If the sump runs dry (loss of topoff water?) then the return pump is powered off.
The only problem selling such a design would be patent issues and UL or similar ratings. I am not sure I would want to sell electronic devices with 120v relays in them! At least without having a UL or similar sticker. A simple solution would be to use the 12v solenoids I guess. As for the patent issues, all we are using are simple latching circuits to control "tank level" every city water treatment plant, refinery, industrail process uses identical designs. In that case sharing your design is not going to keep you from a patent. I do understand not wanting your secret out to other DIYers, then ya can't sell em a control box!
Good luck with your design, and good luck with finding a source of income.
BTW your fabriction of the actual control box looks great!
