Morning all. New to the site and window cleaning!! I have purchased a complete van set up from "Pure water freedom" and all I have to do is connect the leisure battery to the battery (done) and the hoses to the unit and the outside ports, but this isn't covered in the instructions. HELP There is a hose connection on the RO membrane filter( which also has a **** on it), one on the pump and one on the pre filters. It looks to me like the tap water goes in the pre filter connector, the waste water into the RO and the pump to the pole. I cant contact anyone at pure water today as it is Sunday and wanted to do it today. Be really happy for some help please.
