Oh and I'm sure Russ from Buckeye will chime in any moment, not an official sponsor of the site but the guy finds time to visit us and straighten out our messes with RO units here at MAAST. Show me one Ebay retailer that has ever walked us through our issues.

I wholeheartedly plan to replace the 4 spun/carbon filters, 3 100GPD DOW RO membranes and 3 huge canisters of DI resin from them before I fill the 400g tank.
