IMO, your RO/DI unit will be fine. You might have to change certain cartridges for often, that's all. For example, if phosphates are high as mentioned above, you will have to change out the DI unit more often. You'll need to test your output water for Phosphate to know when to change it. But that goes for City water people too. Only way to make a more informed decision than that would be to ask your new neighbors if they have any water test data from their wells.
