Remove the over flow, fill the main tank to the rim (1/2 inch below overflowing) This will simulate a blocked overflow or overflow failure
Then fill the first and second sections of the sump You want as little water as possible in the return area.
Now reconnect the overflow and let it drain into the sump.
(This simulates a return pump failure) When the water stops draining and settles mark the level in the return area This is the MAXIMUM fill level of your sump As long as you DO NOT fill over this mark your system will not flood. If it look as if your sump will flood you'll need to raise the overflow weir so you dont drain as much from the main tank
Most people create their own problems by not following the basics and refusing to stock appropriate to their system. Gregcoyote 2013
