I’m planning out my first sump and I’m very paranoid about floods. My question is: how do you stop your return pump from pumping all the water back into your tank from your sump after a power outage, and overfilling your tank? I read something about drilling a hole just below the water surface of the return line, but I’m a little confused on that. Can someone please dumb that down a bit for me?
