Question about RO membrane

Try flushing out the membrane by removing the Cartrage unit and hooking it up backwards. I couldn't believe the crap that came out of mine and it started working like new again.

Think about installing a flush as well, keeps the membrane cleaner longer.

I think it might have one, where the valve is on that model, there is a little black box that has a cord that plugs into the wall. I guess its an auto flush? It turns on quite often.

Yeah, probably is, if it's working then you shouldn't get much buildup. Depends on your source water though, what's your source TDS?

source is usually between 13 and 20. I haven't had the auto-flush plugged in in awhile so it would have helped to have that plugged in (cord wasn't long enough) but its had a pretty good run of 3 years. I need to change the DI (on order) before I can confirm that I need a new membrane but it seems likely that its the membrane just based on time alone.

Curious, what is the output? Anything to really worry about?
