Started well today - filled up and set R/O running so I could be back at lunch time to refill (I only carry about 200 litres) - £100 done by 12 noon using 180 litres.
Reverse up car to water barrel, fling open tap and put the kettle on.
Check tank is not overflowing and..... aargh! No water!
When I switch on the R/O I let it run for a few minutes so that the resin doesn't bear the brunt of bringing down the TDS reading until the water is coming out the R/O at about 10ppm.
Today I drove off without connecting the r/o back up to the storage tank - so 125L of 000TDS water down the drain - literally.
And now I'm waiting 'til 2pm so that I can at least take 50 litres with me!
