Homemade RO membrane life?

[82cabby]

With proper storage and regular flushes and cleaning during the season, what kind of life expectancy are you all getting from 150 gpd and/or 400 gpd membranes in homemade RO systems? I’ve been swapping them out after 2 seasons on a staggered rotation so very year I replace a couple.

I had four years on 4x400...with ~95 taps. I replaced them for this season with 500gpd membranes, but they were still working fine.

How long they last depends on how well they are cleaned and how often, if properly cleaned you might get 10+ years but if the cleaning isn't up to what it should be, 1 year.
