I use the flush option before I make water each and every time. I am now in my 3rd year of my original membrane and suspect it will last another year or two at least due to the constant cleaning of it.
I flush for a few minutes, until the tds
drops to like 10 on my first sensor, which means that the di
resin is also using less of itself to clean the remaining 10tds up so it reaches 0.
I have been doing it this way for a couple years and its really not a hassle and I only have to change my di
resin twice a year. really worth the extra few minutes.
