After almost a year of working flawlessly, once it tops off with water it keeps dripping and the dripping doesn't end unless I pull the pump out of the water.

Any idea whats causing this? Ill have to unplug and manually top off for now.

#4 is the way I was describing in your other thread, with the exception of having the tube a little higher than the top of the ATO tank.
