XLE 4040 plumbing - which end?
I know that the center port = permeate and outside port = concentrate, but I'm having trouble understanding the correct "end" to go in and out of my 4040 membrane housing.
1) There's no "gravity" benefit to plumbing the sap in from the top, correct? (I'm assuming the pressure does all the work, not gravity) It's easier in my case to plumb in from the bottom.
2) Do the permeate and concentrate come out of the same end (opposite the end where the sap goes in)? Or does the permeate actually come out the same end as where the sap went in? (or doesn't it matter?) It feels like I"m seeing conflicting info on this. To better illustrate my question:
Option A: permeate out and concentrate out of the same end (opposite sap in)

Option B: permeate out the same end as sap in
