so in other words I should/need to change out all my filters!

LOL I guess. I usually start with the canister filters, then check the TDS, then replace the DI if it needs it. Lastly comes the RO if the others don't fix it. No sense in spending the money on a new RO if you don't have to.

Ya good point about the RO. I did read that those should last a while longer than the other resins. Guess that's what I'll be doing this weekend, hunting filters.

Thanks!

Membranes usually last 2 to 3 yrs. I'd change all but the membrane.

My Manual says change the canisters after 6 months and the others after 1 year, course isn't this all dependent on our originating tap water supply quality?

I think I remember reading that somewhere too. 6 months. I guess I'm a little over 6 months so it would make sense that now is about the time I should be changing them.
