Also an alternative for the back up is to use the smaller drain but use a larger diameter pipe than the bulkhead (if 1/2" bulkhead, use 1" riser pipe) in the overflow to slightly increase the amount of water flow it can handle. You can also use larger pipe below the back up bulkhead as well. This will eliminate most of the pipe friction and increase flow.
Lastly just throttle back your pump to match what your drain can handle.
I would use one or more of the above methods over re-drilling the tank.

Some very viable options Thank you . But I did spend like 100.00 on various diamond bits and am dying to use them .
But seriously Ill see if I can upsize the pipes on both sides of the emergency and test that out.
Since I have tirn everything down again and can't test third idea out, my question is this.
When we throttle pumps down with a valve , does this not make them noisier ??
I will start a build thread to carry these ideas on with.
