Quick ATO question.

[craig1632]

I am using only one sensor on my JBJ ATO (I only have one sensor). The sensor is good reading when more water is needed in my sump, but does not seem to signal when the water level is adequate.

Here is the qeustion: the sensor light is always on but I am not sure what that means. Would that mean I need to replace this sensor too?

Any suggestions on how to get another sensor?

Thanks.
