I work with piping, so reading a blueprint or a diagram is no problem for me, plus i watched the video and did it step by step with the video, but here you go. Light blue is in, dark blue is rodi,black is wasteNo way it's deleted that quickly imo. I use an ro buddy and just changed filters after way too long and never read above 0 tds. Can you post a Pic of how you routed the rodi lines to each filter? It can be a bit confusing because of the configuration (imo)
