I am coming back to the hobby after a 4 year hiatus. When I last broke down my system in 2019 I disconnected my rodi and stored it in my garage. I did not drain the system out, so it's been sitting the last 4 years with water in it. Today I hooked it up to make sure all the connections still worked leaked free. Everything still worked great, and I was getting a reading of 4ppm without DI connected. Since it's been so long with water stored in it, I replaced the membrane, and all the filters. Now with the new membrane and all new filters its running at 10ppm without DI. I also followed BRS new membrane instructions of letting it produce 3 gallons of water then letting it flush for 2 minutes. Why do you think its performing worse with everything brand new?
