Nothing to do with not liking it, everything to do with rules. I do appreciate you posting the information for our members.

My RO membrane has been running for 12+ years and still reads 1-2 ppm tds. Membranes can be considered bad when the TDS output goes higher as others mentioned OR when output is reduced to an unsatisfactory amount. My 10 year old cartridge produces nothing near 50 GPD, more like 25. But 25 is fine with me...

I suspect the only reason I got 12 years of life out of mine is due to the VERY clean input water we have around here... It could also be because it is a Kent Hi S membrane, but I don't know how much that means to longevitiy...
