Has nothing to do with breaking. What if something else fails, say my ATO, and pumps my entire reservoir into my sump (which will be 10G once everything is said and done... Then say the power goes out. I certainly wouldn't have the room for that extra water now, nor do I have the space to plan for that, that's where the Check Valve would save me. If they both fail at the same time, well F-Me!!
