When you setup an overflow in a tank you are essentially creating a dam. The top of the dam is the overflow teeth.

If the water level starts to go above approximately 1 inch below your sump rim, start removing water into the bucket to keep it below that level. If the sump water level doesn't go above that point, you are fine. How does a hang on back overflow work?
