Hi guys, I'm in the process of getting a water fed pole system but just want clarity on what everything is for. I'm going to go for a trolley system so I just want to make sure I have it right. The shurflo pump and varistream pump controller as well as the battery are all stuff that goes with the trolley/water fed pole in order to get that system working? As for making the pure water itself I need an RO system as well as di vessells, tds meter and resin in order to make that work? is that how all of that roughly works or am I missing something? I'm also a little unsure as to what connectors I need to piece it altogether. It would be a lot easier for me if I understood what everything is for so I can create a picture in my mind as to how it works before I invest in the equipment. Any help would be greatly appreciated. Cheers anyone that can help.
