from the pic, it appears as tho you're using both a 1" inflow and a 1" return. one typically uses a smaller return than inflow. are you opening the 1/2" return from the Mag 7 to 1"? this may have some bearing on your "overpumping" trouble.

is your overflow box a U-tube type? if so, is the tube clear and free of bubbles?

Renee and i discussed this a bit yesterday, and it doesn't make sense that you can't bleed the excess flow back into the sump with your valve. have you lifted it to confirm that water is indeed bleeding off? i wonder if the return plumbing is so big ID-wise that you're not getting much of it diverted.

it's also possible that the ball valve isn't giving you a fine enuff adjustment, and a gate valve may be a better choice. as much as i dislike adding valves directly inline, you may need to restrict the outflow of the pump itself.

just thinking out loud here...
