I normally change my DI resin about once a month (say 600 litres of product water) and my 75 GPD membranes last a year or more.
I got a new membrane and new batch of resin and fitted them at the beginning of September they lasted nearly 3 months before the TDS got up to 3ppm.
My most recent change was on 14th Dec when the TDS had got up to 5ppm. Five days later it's already up to 5ppm. It's at 7ppm after the RO membrane.
It looks to me like the membrane is failing. Any suggestions what's going on here? What am I doing wrong?
