RO too fast
RO too fast
(OP)
RO system (with sediment and carbon prefilters) is rated for 24 GPD and actually operared at that rate for a half a year or so, with a waste rate around 70-80%, but recently started producing 2-3 times as much at about half the waste rate. Pre-filters changed. Filters and membranes are properly seated. It's still producing 50-75 GPD at 50-60% waste rate.
What gives?

The RO membrane is 11 months old. The package says to replace every 2-3 years or 10,000 gallons. I've done less than 2,000 gallons. I do have an unopened replacement membrane handy, but was hoping not to use it so soon. (Then again, I just read that RO membranes do have a shelf life. I got my replacement membrane about 5 months ago.)

I would add that the shelf life is not important for this application. You should also be sure to get a good quality sediment filter. Perhaps a prefilter of using 5 Micron polyspun cartridge and a final filter with 0.5 Micron rating.
