Ya I do, I change the RO membrane when it reaches 10 ppm. Right now it's at 2 ppm.

Yes. No.
I have thought of this as well. I will measure and time myself flushing tomorrow, and calculate that in as well as proposed waste when using an auto flush. Before installing the 75 gpd restrictor I would manually flush the same as I am doing now so there isn't a change there for me.
