Russ, my TDS is 288 in and my out is 2. This is after replacing the sediment, and carbon block. I recently replaced my RO membrane, which I ordered from you guys. I also am running through 3 DI chambers. Please help me figure this out. I bought the dual DI and membrane 8-21 Oh and my pressure is at 62

I just dont think 100 gallons should be killing RO membranes that fast.
