I Just changed all my pre-filters in my RO unit, membrane is about 2 years old and probably should be changed asap....unfortunately I don't have a TDS tester....but I could take a sample into the local water place to get it tested tomorrow. Our water is surface water...mid summer it is around 80-90 right out of the tap.....but I've never had it checked during spring run off.
