Drains in the overflow

[Bowhunter4250]

I know this sounds simple and maybe im looking too much into it ?
I will be setting up my 180 and i wanted to use the return side in my overflow boxes as drains ... So therefor i would have 4 drains , now couldn't i make that return side into another durso so basically having 2 durso's in each box ?
Would there be any draw backs to this ? Im setting up a basement filter system and will have a large return pump

thanks

you can do it, but they are different sizes, or should be. Usually the drain is bigger than the return. Keeping that in mind, I don't fore see an issue. How are you running the returns then?
