I have been working sometimes at 22, ... the average is 0 - 30ppm. But I reckon 30 it's to risky here in the South.

Mine stayed at 0000 for about a year i was`nt using it a great deal for the first couple of months since then probably between 200-250 litres a day, flushing once a week for 10mins i have replaced the carbon/sediment fiters every 3months, yet to change the resin though

When you have a TDS of say 15 it does not mean all water at 15 will be the same. It will depend on the nature of the chemical and trace elements in that water.Some of the elements are in  a suspension,some are in solution and some are gasses. This mixture will determined the out come of your cleaning result.  So in  conclusion if we took water from say 10 areas in the U K and all had a TDs 15 and we analysed  then each one would contain different chemicals.Some would spots some not and some will form spots with persistent use of the same water.
