Flushing doesn't work for tds creep. Flushing normally means running the unit wide open thru the "bad" output line so the water flows over the membrane to "flush" it. This is useless and not needed but is a great marketing gimmick. To get rid of tds creep you have to by-pass the DI unit for the first minute or two when you start to make water. This way the tds creep goes down the drain instead of the DI unit. No harm in not doing it, it will just exhaust your DI quicker.
I think it does the good option you described. This is the unit: https://www.coralvue.com/icecap-rodi-smart-water-filtration-system
But I added a cation, anion and additional mixed di chamber for better visual verification of when a change is needed.
