ppm levels not changing

i have my rodi system set up and it’s testing the same as tap(260 range). i’ve made probably 20gallons worth. what could possibly be the reason it isn’t doing anything?

Check you’ve set it up correctly and all the filters are in place and also the DI resin. It sounds like something isn’t being filtered correctly as it should produce 0 TDS water.

Also check you have taken the cling film wrap off the filters. I say this because on my first RODI system I left them on for 6 months as I didn’t notice them. I was burning through DI resin like crazy! Lol
