Thanks everyone for your feedback!
I'm not able to place my reservoir above water level so I require a transfer pump and I've no room in my sump for a toilet style float as a backup.
For you DIY'ers, where do get your ATO parts and which float switches do you use? I want a system with a fail-safe, but again no room for a toilet shut-off so how do you wire up two floats to the pump?
The plug and play ones of course use a controller, which have a third fail-safe that will shut down if 6x last fill occurs.

Ok I think I understand. To use two float switches with a transfer pump, a harness is needed to plug both switches into the pump, one higher than the other. If either switch is closed, the pump won't run; both must be open to activate the pump. I don't know where to get one of those harnesses.
