ive got a 5 stage ro unit that does 200 gpd,just got some new membranes for it,went to pick it up and the lad said it was wired up wrong,so he started messing with it,now the tds comeing out of it is 200+ before it was in the 70s,he did say its def wired up correctly now as he has done it.ive only done it against the tap so maybe pressure is to low for it.Any ideas or comments,and i havent changed the membranes as of yet.
regards
