The part where leaks could occur works fine. Its underwater so it would have to be a little airtight and it seems that it is. There are no bubbles coming from it.

Still not a perfect system. Too little water intake results in air flowing out the water intake and the air pump needs to fight a lot more than it should resulting in extra noise.

That's a good idea thanks. I don't need to apply it right now but i see it coming in handy in some other projects.
