Going to mess with it tonight after work, thanks for the help and ideas

I will try to take the tank out of the equation see if that changes anything

Here's a pic


Flow goes

Prefilters > membrane > di resin > T off one way goes tank other way to remineralied filter for drinking , there is another T between tank line .

So if you open drinking water line water will flow from tank or di resin through extra reminerazed filter to your glass , if you want RODI water for tank you use T off like water doesn't pass threw that filter water comes from storage or from di resin
