Is it the horizontal runs? That would mean a whole redesign of the basement, moving the sump across the sump room 15 feet.

Bean has posted pretty specifically several times in his thread at RC that this system won't work with horizontal runs. He hasn't offered any thoughts on a solution for horizontal runs, he's just said if you've got horizontal runs, you're not using his system so he can't help.
Most of the problems people have written about are not with flooding, but with noise. The issue there is that the open channel stops being an open channel if it's not pretty much vertical. The theory of operation is that the water in the open channel clings to the sides of the pipe as it washes down to the sump, but sharp bends and/or horizontal runs wreck that effect.
I'm just about to test my own basement sump beananimal, and I've unavoidably got a couple of 22.5 degree bends in my open channel. I am hoping that it will work without issues...
