So just so I have a clear understanding... Is this representative of the orientation of the sensor in your sump, in the return section with the pump, with the waves being the desired water level in your return section?
If it is, have you physically held the float sensor in its lowest position to see if it triggers the pump to go on (it should)... If it doesn't trigger the pump to go on, then it's definitely (in theory lol) a bad sensor.
