This question is for anyone who’s TDS from the tap is lower than 150 ppm.
My 3000 gpd RO brings my tap water down from 500ish to about 4 in the winter and 7 in the summer. Does anyone whose tap water is a lot lower than 500 ppm achieve any lower TDS readings after the RO?
The reason I ask is because I don’t use resin and I'm just wondering if I could bring this reading down any lower with just an RO alone.
