No difference between your Flow Pur and my On-The-GO Brand.
It states to backflush for 5 minutes.
All you are doing is 'fluffing up' the resins, so it does not take long.
If also going to do a regen....backflush first.
Six weeks between regens is about what we got routinely....2 adults.
They are definitely worth it when water supply is hard.
Is it time for your medication or mine?
