right I think my RO membrane has had its day, my tap water is 205 and is coming out the RO at 28, I've tried flushing and still no good the RO is a year old, I have just changed the pre filters which where way over due and I think this may of been the cause of shortening the life of my RO membrane. My water pressure is not the best so I have a pump ordered and on the way, so do you think my RO Is done with, as when I first had it the water coming out the RO was around 8-12 thanks for any help or input
