ABSTRACT The partial vacuum produced at the inlet passage of a vortex chamber is employed to move liquid from one compartment to another in order to maintain the level of liquid in at least one of the compartments within a predetermined level of the liquid in the other compartment. In one embodiment, the vortex unit or other suction means develops a partial vacuum at the maximum height of a siphon tube extending between the two chambers, the vacuum drawing fluid from both or at least one of the chambers to the top of the tube thus initiating siphoning. A sump pump having a negative pressure insufficient to lift the liquid to the maximum height of the siphon tube is employed to deliver liquid to a load and concurrently to the vortex unit to establish the required partial vacuum to initiate siphoning. The vortex unit may also be located in the siphon tube and may be used as a pump to deliver liquid from only one compartment to another or in another embodiment as a siphon to move liquid in both directions to maintain liquid in the two containers within a prescribed difference in height of one another.
