Is anyone here using this type of top off. Just set mine up and i am having problems with it. OK i set up both sensors in my sump one to activate the pump when low and the other to deactivate when high. The problem is that my pump is not producing enough water to be able to cover the difference between sensors. This ATO is equipped with a timer that automatically stops everything and goes into a stand by mode. I set the timer to the max allowed which is 14 minutes but still not enough time. Does anyone else have this problem and what can i do to fix this. Running a bigger pump is not really an option. Is there a way that the timer can be removed? :-[
