Not all applications of a check valve are as all dire as all that though. I needed a check valve because otherwise my zeovit reactor would dry out in the off periods as the rocks were higher than the waterline in my sump. Although having said that all I did was buy the check valve and then never installed it, and just ran the zeovit reactor 24/7. Ooops.
Although I agree, I'd rather have a sump return line without a check valve. It's just asking for trouble sooner or later. My favourite sump return setup involves having locline right at the surface - no siphon hole no check valve no sump overflows.
