Ian,
Im very intrested as i mite set one up myself, as my tds rises slightly as the tap does. never seems to be stable in this area

was 350 last week now its around 380. so was thinking mabe best to set a softener up as by the looks of things sounds pritty cheap. vessel and softening resin?
how do you recharge it with salt? i dont know anything about a softener so any info would be great.
