I tried using one of those aqualifter pumps with my JBJ auto top off system and it did not work well at all. The float switch would trigger the aqualifter to come on, but the flow rate was so slow that the signal from the JBJ top off unit would somehow "time out" so that electricity to the aqualifter would cut out, but the unit would still show that the float switch was too low and the pump outlet was still energized. After this, it wouldn't matter how low the sump got as the unit would not reset and try pumping again unless you manually flipped the floatswitch up and then down again. I ended up swapping the aqualifter out for a mini-jet pump but this does not work perfectly either as when the JBJ unit enegizes the pump outlet, the pump remains on for a few seconds too long and more fresh water than is needed gets pumped into my sump. Not too sure if anyone else out there has had this problem but I'm assuming it is just a flaw in the JBJ unit. Might be worth going with a different auto top off unit like the tunze or tsunami.
