Which manifold design
 

So trying to figure out which manifold design will give me the best flow charectoristics.
Even flow in all sectiond to minimize channeling.


The cross tubes (the ones not in the first pic) will not be slotted. Even spacing between sections, half distance to walls.

Leaning towards 3. I'm not concerned about the extra $4 and something in fittings and pipe or extra work. Just max efficiency.

Are you going to batch sparge?

If yes, the manifold design doesn't have any affect on your lauter efficiency.

If you are going to fly sparge, JP has researched this thoroughly:

The contributors above have said it all. Read the Palmer pieces for some great advice.
