Is this RODI setup correct?

Although it probably came that way from the vendor, there is no need for the GAC "Taste and Odor" filter that is plumbed in after the DI cartridge. After the water leaves the DI stage it is as clean as your system can make it.

Also, contrary to how your vendor originally made the system, a horizontal DI stage is a fundamental configuration error. Remove the DI stage from its clips, and orient it vertically with bottom up flow.

Additionally, we recommend against running the DI out put to a pressurized storage container. Be happy to explain why if needed via PM - not interested in educating the ebay vendors!

I re-pumbed the unit and closed the valve. I hear pressure inside the unit and water is flowing out the YELLOW waste tube slower but still at a pretty fast rate. Nothing is coming out of the GREEN tube where the arrow is.

Any more ideas? I almost gave up and am on the fence of using tap water.

Take some new pictures. if you have it plumbed right and the restrictor is closed and nothing coming out the supply, then possibly something is wrong with your membrane. Measure the waste water over time. At 100 g per day product at a 4:1 waist that would be 400 gallons waist per day or a quarter gallon a min. Check if you are around that.

Snap a couple of pics to show how you have it plumbed now.

I don't see an auto shut-off valve in your photo & the diagram sphelps provided has one of these just to the right of the valve/restrictor assembly. Another photo would help troubleshooting for sure, perhaps a couple showing the system from more than one angle.

Heres another pic. Sorry I didnt get any from more angles. Correct, there is no auto shutoff valve.

Nothing is coming out of the green tube, only the yellow. Im stumped!

Red: In
Blue: Out
Yellow: Waste
Green: RO out

Chief - you still have it plumbed incorrectly. Look again at the diagram someone posted earlier in this thread. You have the second carbon stage feeding the flow restrictor - it should be feeding the RO membrane.

Also - get rid of the pressurized storage tank if you have one, and get rid of the taste and odor filter that is above the DI resin stage.

Good eye, it's actually evident in your first two photos as well. The flow restrictor/flush valve is supposed to be plumbed into the yellow waste line. The white tubing from the prefilters should go directly to membrane. Looks like you'll need a longer piece for that (or flip the membrane housing into the other direction). This is where the auto shut off valve would normally be plumbed in.
