Hi , I've just bought this second hand 300 gpd ro by streamline has anyone got any clue on these how it's back washed or even set ? It's working and producing 5 ppm water but the waste is huge ,they is a Allen key to turn to slow down the waste but if I do that what damage will that do if any to the membrane? I know it's not a lot to go sorry /emoticons/sad.png
