I picked up a used kent HI-S 60gpd ro-di from the guy i bought my 210 and chiller from and after sitting in the garage for the past 6 weeks i finally got it cleaned, new filters and membrane and producing water. Its about dam time.So no more lugging buckets back and forth for me. I plan on pumping water directly out of my sump thru a wall for water changes and back in to fill. How have some of you gone about remote drain and fill. doubt thats the correct terminology. thanks.
