Reverse osmosis system

I have a complete system it has its own pressure tank and is a large culligan system. It came out of a coffee shop in Minot and was only used for couple years it went out of business. I decided to go a different route so never used it myself but it all worked when we took it apart.There is more parts to the system than is pictured here it is a complete usable system but I have the filters and other parts in a couple totes and didnt want to drag them out for pictures.
