Hi mate
Thanks for your call today.
Have a look in the "business for sale" section, that's where I'm advertising my van + equipment. But first of all check if you have soft or hard water where you live, that will tell you if you need a DI or RO system (mine is a DI - soft water). You can check it either with a TDS meter or with your water supplier or ask someone on the forum that may live in your area and know.
Cheers
