But your return lines of the closed loop are probably all at the top. If I have the intake in the actual overflow box, then water would go through my bottom return lines, siphon and drain the tank in a power outage right? At least up to the level of the drain in the overflow box. Mr. Alberta had that happen a couple of years ago.
