If you pump down, gravity and siphoning will prevent the check valve from closing of it is a flap style. It needs to eject into a larger vented pipe above pump level to prevent the siphon. An open check valve would allow sewer gas to enter.

I would hope he properly vents it and there should still be water in the bowl to seal the gases out.

This is interesting. I will be appropriately venting. Seems like that would be the only issue. Also looks like I can hide the box in the wall on some of the models.
