    An overflow box works on a siphon system. But it also works on a equilibrium system. There are two areas (a) and (b), Area (a) controls the height of the water in the tank and is situated inside the tank. So when there is a power out the whole tank does not get drained. Only the water that is above the overflow level. There is a syphon pipe that go's over the tank panel into area (b) this transfers the water from area (a) to area (b) and keeps the two levels in equilibrium. Area (b) has a divider in it that is similar height to the overflow height that acts as a overflow to the water outlet. The water does not syphon back down to the sump it simply drains.

    When there is a power out the water in area (a) and (b) remains in equilibrium (same height) As soon as the power comes back on the level in area (a) rises, the water is siphoned to area (b) (equilibrium) and starts to overflow to the drain.

    Hope that explains for you.
