Herbie style overflow

[Chad]

Ok, the hole does not work.. I am a bit peeved that I did not do this right!! lol.. Anything else I can do to fix this mess? Or will I just have to suffer with it or re-plumb it?

No matter what I will have to go through the back. The best solution I can think of is to remove the current drain and replace all the 90's with 45's. Or just replace with flex Pipe.

Ideas?

What if I tap a hole in the very first 90 out the back of the tank, run a line to the return pipe inlet, so it sucks out the air? Yes it will kill some of the return flow but very little I would think? Yes/No?

Thanks!!
