Anyway, I'm sorry about your misfortune although I'm glad you didn't lose the tank.

This is a great idea if you don't have a big ATO reservoir connecting to the system directly. Else your low switch wont activate uitl the ATO reservoir is out of water.
What i do on my is that put a high float switches on both my sum and my display tank , if the water reach these levels, my pump shut off. Also have the water floor detection as well to shut off everything. Cant afford any water on my carpet or my wife will kill me
Also, about why you are getting overflow, i found that sometime if your overflow water has to travel horizontal to get to your sump, the air get into there and build it the back pressure which cause water could not drain fast enough
