Is this RODI setup correct?

I think it is still incorrect.

First: look in the white filter housings below the bracket. Need to know what is in each of those. The way you have it plumbed now, you should have a sediment filter in the right housing, carbon block in the center, and carbon block (or leave empty) in the left hand housing. These three prefilters MUST be in this order. I think your's are not.

It looks like you have the tubes on the right hand end of the RO membrane housing reverse. Figure out which of the two ports is your waste water, and which is your purified water. Here's a way to understand it rather than memorize it:

The water purified by the RO membrane exits the center stem of the membrane. Identify the port that comes from almost dead center on the end of the housing. The other port contains waste water and is located on the edge of the end of the RO membrane housing:


Once you get it hooked up correctly,
1. Remove the clear DI stage from its clips and orient it vertically with flow going through it from the bottom up.
2. Remove and do away with the final stage that comes after (is on top of) the DI stage.
