View Full Version : Which way should DI water flow?

11/19/2013, 06:14 PM
I have the color changing DI cartridge in my system. link (http://www.airwaterice.com/product/DICC/DI-Cartridge-Single-Color-changing.html)

I bought my RO/DI used, and since have re-piped some things myself.

My question is which way the water should flow through the cartridge?

Currently I have it flowing from the top to the bottom, or from the inside to the outside, depending on how you look at it.

Is this correct, or do I need to reverse it?

for a DI resin it does not matter. Mine is piped the other way so it would flow outside then to cartrige and up middle and out. Hope that helps
