The vented secondary is to be set up to turn in to a full siphon fast if a problem occurs. It also helps the system settle in quickly after power up.

The emergency stays dry unless the sky is falling.

One touchy area is the amount of pipe below the water line in the sump. Too deep and the full siphon won't settle in at all. I went down to about 1.5" and it seems ok. If this is wrong it can seem like the whole system is crap and impossible to dial in.

Thanks for the tips, have you tried running the drain in a filter sock?
