Nothing will go wrong with my ATO, it's PLC controled, and yes, it's on a float sw. I dont have the sw control the pump directly, there is a timer programed in. A 'debounce' timer. The floats like to bounce a bit. turning on/off/on/off. This is hard on pumps. The Debounce timer is set so the float has to be ON for X time, before turning the pump on. Presently, I have it set for 20 minute's I think. Which equate to 2-3 cups water evap. If I lower it to say 1 minute, it should be <1 cup. Longer times mean less pump cycles, less wear. Starting and stopping is harder on contacts and motors than leaving them run
