haha did it come with an aqualifter pump? you fill your tank to where oyu want it then level the overflow [with all water flow off for calm even waterline] with the water line but on the edgy of starting to overflow... then attach a piece of airline tubing to the in [suction] nozzle and the other end to the little nozzle on top of the overflow box that sticks out, and thennnn you take another airline tube and attach it to the output of the aqualifter and just dangle the end into the back of the overflow... turn on your aqualifter... turn on your return pump in the sump... when the water level rises and overflows into the cpr unit, the aqualifter creates a siphon by evacuating the air in the chamber and replacing it with water,,, it also pumps water safely so you simply leave it running in case of a power outage... then wen the aqualifter is restored,,, the siphon will be as well.
oh also my intuition is that it is useful to fill the sump to just under its maximum capacity especially in such a small broken up sump like mine... that way you can account for plumbing and such but prevent a spill or actual OVERFLOW if the power is turned off... assuming you have proper check valves on your returns and such :)
PLEASE SOMEBODY EDIT THIS BECAUSE IM DEEFFFINITELY NOT AN EXPERT ON PLUMBING AND SUCH...
