Getting back in after 15+ years! Sump Filtration Questions

+1 on the RODI system. I figured you'd get one automatically, but if not I'd definitely make that number one on your list

Do have an existing RO/DI system in the basement. Just need to hook it back up. Will probably buy a new membrane and new resins just to be safe. Start fresh all over again. I think it was a 75gpd setup. Should work fine for the time being- I'm in no hurry to fill this thing up until I have everything as perfect as I can get it.
