I have noticed tds out of tap gone from around 75 to 150 + . not sure when it happened as I am only doing a few jobs now and again as only part time so don't need a lot of water .
Still get 000ppm out of di vessel and have 2nd vessel to go double di as an option, but I would like to get a ro system but not sure what I need, got good tap pressure and not on water meter, probably 75 /100 gpd would be plenty for now.
Can anyone recommend a good system please?
