86890, RE: should i decrease my piping size? Posted by DarkOne, Dec-31-69 06:00 PM
Think about this: What's the outlet size on a 25G? What's the outlet size on a 20G, 16G?
If you have a 2" outlet, use 2" piping. if you have a 2.5" outlet, it makes sense to use 2.5" piping.
If you have a 2" outlet but eventually might upgrade to something larger, its not going to hurt anything to use 2.5" piping.
