Agreed. Big changes like that in an established system can cause you more grief than anything. I'm pretty big on the RO wagon, but in your case I say let it be!!

If you persist, I do agree that you should just buy your own RO/DI system (don't forget a digital TDS meter!). Should cost you about $200. Waiting for the bottles to fill, and lugging jugs of water around gets old REAL fast especially with a tank your size.
