Today on my rounds I've been dipping customers water butts to see what the tds readings are in my area. Lowest reading was 20ppm and the highest reading was 35ppm. Most of the butts I looked in were pretty grubby to be honest. I reckon with a filter my rainwater would be quite reasonable. Better than the 380ppm out of the tap.
I was dreading reading this thread wih such a subject line.
