Okay guys, I'm about to take the plunge and start going to wfp.
Live in a very hard (and chalky) area, so know that I need a system with an RO. Seen two vans on fleabay, one close to me, with a heater in the door....so whats that for, and is it important?
Also seen a couple of systems, but with Carbon and Sediment filters - what are they for?
Trouble is, if you go onto any of the suppliers websites they give you all the features, but none of the benefits !!!
Thanks, Andy
