Good to know, I run two on my 210 and they have a clear housing so you can see if anything gets caught in them and nothing so far, been up for almost a year. Either way my sump can definitely handle the extra water anyways so I'm not worried if they happen to fail but they still work fine.

I guess as a failsafe they are ok but I would not become dependeant on a check valve no way in hell.

Good to know. Thanks for the pointers

Fortunato, the problem is not that they never work. They'll work 100% of the time, until the moment they don't work. Then you could have a flood. Odds are that it'll clog when you're not home either.

Like Tony said, never ever would I rely on a check valve. It actually gives you a false sense of security. I'd never ever use one on my own system or any customer of ours.
