I’ve had the same RODI system for a few years now. Over time I’ve replaced the filters and DI resin. But when should I replace the RO membrane?
Thanks in advance

How do I measure rejection rate?When rejection rate reduces
Acceptable rejection rate is 98% of incoming TDS, so if your incoming side says 498, and you're reading 1-2 on output, the membrane is likely fine. If you're reading 318 and the output of the RO membrane is 7-10, it's probably time to replace it.How do I measure rejection rate?
Are you saying when my TDS is no longer 0?

Product water changes for me with the seasons due to the temperature of the incoming water. I see much faster production in the summer as opposed to winter, all due to summer’s warmer water here in Maine.Also when the water output decreases it's time to change the membrane.

I have always used rejection rate to guide my membrane changes. I was not aware that production could be used. Do you live in a place with constant water temp? Or do you have your ro membrane plumbed into both your cold and hot water lines?
I live in Washington D.C. We have the 4 seasons of weather. My unit is plumbed to the cold water line only.Product water changes for me with the seasons due to the temperature of the incoming water.
