You could always redirect the condensation line directly to the entrance of the foundation drain line, this way the condensation would never make it to the bottom of the sump pit.



FUNNY STORY TIME :
Knew a guy who had almost the same set up as the original post, his solution was to drill holes in the bottom of the sump pit to let the small amount of collecting water to seep into the ground below the pit.......he couldn't work out why the pit filled up to the drain line with water and never went down past the drain entrance, he didn't figure on ground water coming up.
DO NOT DRILL HOLES IN THE BOTTOM....lol
