ATO Circuit and outlet

Did you flip the float around, it looks upside down? You can remove the part of the float that moves up and down, take it off and put it the other way. Make sure the float is set how you had it before when you did have voltage on the port.

Dear Rob,
 
From my understanding, the float must be placed above the sensor with closed position. If the sensor fails to stop the pump, the float will do as a backup.

I attached some pictures of my set up for the testing. I my case, the sensor is not stopping the pump.
