I ran 4 vans with no RO. It's not cheep. The most cost effective way of doing it is 2 D.Is (as big as possible) in series in the van. When you get a reading over 000, move the second bottle back to nearest the tank then replace the resin in the other, putting it back nearest the hose. This will reduce the amount of good resin that you throw away.
 Hiya, what was your TDS reading from your tap? mines around 250, I'm gonna go with this idea & also pure freedom reccomended 2 pre filters before DI vessells to keep resin costs down, do you think a good idea?. I'm filling a 650 tank, what size tanks did you have & how long it take to fill?

Thanks, Kristian.

PureBrite do you not know any of the other local lads, Im sure someone could sell it to you at a monthly cost, this would surely save you money in the long run, I personally wouldnt want to be di only with the tds we have here as I had to fill my tank once straight from tap and it killed the resin so wouldnt want to do it again.....
