Making an internal overflow (HELP)

[paddyob]

My tank came drilled with a single overflow and two returns....

A friend suggested that I should have a second drain for "emergency purposes" in case the drain becomes plugged.

can anyone else shed some light on this.... if its absolutely necessary or ways around drilling another hole?

Use one of the return's as a second drain? Post a pic of the tank so we can get a better idea of what you are up against.

Posted above. Center overflow and two return... one each end.
