Herbie style overflow

[Nevin]

As Mark says, you can do the Herbie through the back wall--just turn the elbow upward or remove it. Then adjust your gate valve so the main drain is fully immersed and the emergency drain isn't. I have a similar setup with an internal overflow smaller than yours--can be a bit tricky to maintain the water level, but it works well.

It should work fine with the hole. Removing the elbow completely will also work but since the primary is so close to the top air may be drawn into the line from the surface which could be noisy, the elbow should eliminate this.

Run it with the elbow and hole and let us know how it works.

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!!
