You are referring to the water returning into the tank. If pump off then water can siphon through the pipe back to sump tank. That's not what I meant. But, thanks for the tip!!

Oh, so you mean there's a pipe behind the over/under flow conpartment in the main tank that regulates the water flowing out of main tank and into main tank? So, in this case if the water stop overflowing into the compartment, the water from the under flow will not be strong enough to reach the opening of this pipe to flow into sump tank?
