I went with 1-1/4" on the return for a couple of reasons - as I stated up above, I used to work on industrial hydraulic systems, and return line back pressure is to be avoided at all costs. In this case, I wanted to make absolutely certain that the upper rez wouldn't overflow. The incremental cost of the components was only a few dollars more, so.....
I'd agree with rives. I started with supply/return the same size...no bueno. The supply is under pressure from the pump, and is delivering more water that a same-size line can return unaided. I believe I was running 1/2" supply and 1" return on my gravity system.

Have a good day and hit the ignore button on me, then I won't have to respond or listen to you
It's not an insult to call bullshit on a bullshitter. I'm not threatened by "knowledge"
, but I'm annoyed by people spouting senseless bullshit
. Like I've said, I have clearly shown the inconsistencies of your statements, to which you have no answer. I have asked several reasonable questions regarding your statements, all of which you have chosen to ignore. You've wasted a fair amount of space telling us all how smart you are, but I've seen absolutely nothing to back it up. You keep bashing a system that's proven to work based on mine and others experience. This tells me either: A) You have no idea what you're talking about
or...well there really isn't an "or". I'm not in charge of this thread, but it's always open season on "people" like you. Either say something serious, or crawl back in your hole
