Are you sure the way I have it doesn't have the same effect? I don't know, just asking. I mean, do you really know, because I sure as heck don't. I've never had a drilled tank before.

The gate valve is adjusted so that the tank's water level goes up a bit and covers the intakes so that they don't suck up air. It'd be using the whole tank as its own great big overflow box. If the tank water ever gets too high, the third overflow, the backup, will start draining the water.

I know it would work but what I'm not sure about if it's going to be quiet enough for my liking.

If it does make a bit of noise from air getting sucked in I suppose I could always put a reverse durso on the drain in the sump.
