I just replaced my RO membrane a month ago. Today I tested the water and to my shock it's over 100 TDS. I've confirmed this with an inline and handheld unit. I'm at a total loss as to whats happened. I have two sediment pre filters as well as two pre carbon filters as well. They still look good.
It's always easy to see an exhausted sediment filter but mine are only partially dirty. They were all replaced new with the membrane.
In the past I have always gotten at least 8 months out of a filter.
Any ideas out there?
Stupid filter
