[Erithwc]

Right a backpack it is then  I did think about buying water erithwc but not sure how much people would charge? I think I'll just buy a small DI vessel to start with.

Another question, is it true that it takes more than on clean to get windows up to standard using wfp? Or is that just a myth I heard?

you need to check your tds if its to high you will need a ro system aswell as for buying water i dont think its expensive you need to decide how much water you need per week.

If there is anyone in the Canterbury/Kent area that would let me come out to learn wfp with them it would be greatly appreciated I wouldn't of course expect any money and would be glad to gain the experience.

So can I not just use a DI vessel instead of a full RO system to start with?
