comments to rban's diagram
-have the back up a little higher and run dry
-use gate rather than ball for easier adjusting

There are great drains. Been in front of 2 different tanks each flowing about 2000gph. Truly silent, no gurgling in sump, the only nosie you will get is from the waterfall effect into the overflow chamber so keep level high.
