drain return line sizes

[dapple]

What size pvc lines should I be using for the drain and return lines. The return line is going to a Y fitting to braided flex line to the bulk heads. The drain drops to a T fitting one to the fuge other to sump. Gravity fed fuge to sump.

well my sump and the over flow i want to get are set up for 1" fittings and pipe so I'd assume 1" :Cheers:

I would go 1 inch also but would drop it to 3/4 on the return where it enters the display to get a little extra pressure coming in..

Killer. That's what I was planning to do.
