Is this the best ro to use for least waste water. ? I got 150 odd tds , it was around 70/75 but has been up in 150's now for around 9 months for some reason.
I am going double di as soon as resin wears in 1st vessel .Not too bothered at present as only part time and still building work but would like to have something in place when demand goes up.
I dont know about ro so any advice is welcome, probably looking at 100 gpd max also not on meter. Ta Pauly
