RO filter

Water goes from clean out on RO to DI

Water comes back from DI through reverse stop. Yellow is to pressure tank and blue to RO/DI faucet

When I got my first Carbon(can’t rember the brand ) I had to flush the carbon.
If you have cheap carbon and high cloramines from city water , it’ll burn the carbon up fast then eat the di.

Well water will eat the di too.

I wonder if that's the deal
 
My city water is 370 from the tap.
I don’t burn resin like that. Any more that is.

Went with a better carbon from BRS
Like $3-4 more. Kinda dum they even sell the junk carbon
 
Although you could certainly improve upon the prefilters that came with that system, they certainly are not the cause of your low quality RO water. We can help you with those if you'd like.

Hard to tell from your pictures, but is your system plumbed such that RO water from the pressure tank makes its way to the DI? If so, that's a plumbing mistake.

Have you checked to assure your membrane is fully seated?

No, pressure tank if after dinner. Yes I took it apart and made sure it was seated first. iSpring is sending me a new RO membrane after troubleshooting
 
That is REALLY an odd configuration - you really should not have DI water sent to a pressure tank if you're at all interested in system efficiency.

Our Reef/Residential RODI System has a pressure tank for drinking water that is filled with RO water, and a DI stage, but RO water from the pressure tank never goes to the DI stage.

The water in the tank has already been thru DI so it's ready for use. I cannot wait for water to trickle out thru DI when I need it
