orthokardia
New member
I have an older aquasafe 5 stage RO/DI system. I replaced all three prefilters and the membrane with BRS filters. I have made about 200 gal of water and have exhausted two DI recharges. The TDS levels are 68 from the tap, 68 after the prefilters, and 22 after the membrane. I am currently without DI, but the post DI TDS was 2 before exhaustion. What is up??
