The larger the pipe the less head pressure you will have allowing more water volume to go through the pipe without working the pump to hard, I'm running 1.5 inch on my return discharge on my quite-one 6000 at aprox 8 feet of head pressure and it's still pushing over 1400 gph and the pump with no head pressure puts out 1600 gph if you go smaller size on the discharge it will not work very well, check this out it may give you a little more insite on line size..
In order to maintain a "reasonable" amount (or "control" the amount) of flow we need to give it some "breathing" room...
As the line gets bigger...the more "flow" can go through...(within reason)...
So a Mag 12 - 4' head with 3-90* elbows will "deliver" ...
761 gph with 3/4" line...
942 gph with 1" line...
1037 gph with 1 1/4" line...and
1061 gph with 1 1/2" line...
You can see there's not much gain going to 1 1/2" line but there is a gain in flow from 3/4" to 1" and 1" to 1 1/4"...
That's just for this pump... and other makes and models will be more effective at other varining sized lines...
