Just wondering,
If I was to buy a 25L DI Vessel and used about 250 litres of water a day, can some one give a rough idea of how often I would have to change the resin?

The water in my area, Im told is around 100tds max

Im just trying to get a rough idea of what sort of running costs I will encounter.

Im also looking for some info on how the Reverse Osmosis system works as I cant seem to find anything on it.

Sorry about the amount of questions guys.

Thanks in advance

The merlin is the one Im looking at this very moment,  My problem is that Im not too sure how the RO system works.

Can it be fitted to a setup in my van or does it have to be one of the setups I keep hearing about in peoples garages that have to filter the water over night then transported to the van etc?
