An RODI is the last major purchase for the tanks that Im setting up (yea I know shhh I had to tell my wife something). Water pressure where I am is low so Im going to need something to increase it. Im probably going to settle with one of the brs 150gpd 6 stage rodi's. I was looking at the boosters they have and some of them say other parts are needed. Id like to get this order in while the sales are still going on. Can someone please explain what additional equipment I need to get to increase pressure?
