I am having issues with my DI resin depleting too quickly (after 30 gallons or less). I am on well water and have a TDS of around 17-20 (it fluctuates). So I bought a 4 stage RODI system from BRS with water saver (2 RO membranes). Yesterday I added a booster pump because my pressure was way too low (25), because I thought that was causing the issue. After I added the booster pump I changed all of my filters including my RO membranes,and I flushed the new filters individually as per the directions. Then I changed out the depleted resin, and ran a batch of water overnight. When I went to bed it was 4 TDS before the resin and 0 TDS after. I made roughly 30-35 gallons of water and it reads 1 TDS this morning. My system now reads 4 before and 4 after the resin, and it has changed completely to brown after only making about 30 gallons of water. Any thoughts as to why I am having this issue? Or suggested fixes?
