If you have that, then your membrane has a hole in it. And your DI filter is depleted. Barring everything else, your DI will bring the TDS down to 0.
Check the TDS of the water coming out of the ro membrane. It should be about 95% less than your tap water.

I am on city water - it could be I don't know what i am doing with the unit but i also am sure that the DI resin is depleted now that you mention it. The unit has like a valve at the waste water line that if I keep it mostly closed i get close to 60PSI however if I fully open it i get maybe 20PSI.

Are you sure your rodi unit is connected properly.....sounds like their is no flow restricter installed or the flush valve is open

+1
That valve is for flushing the membrane.

I actually found the video very helpful however I have different valve on mine that I might consider throwing out.

That is a precision type of valve. Forget the name. The last person to install that probably used it as a flow restrictor. If so and if everything else is hooked up properly, then you adjust that valve so that when you get 1 liter of ro water, 4 liters of waste are produced.
Do you have a pic of the other side of the ro membrane housing?

I'll grab some more pictures tonight but I also think my DI cartridges might be screwed
