Hello,
I've had this RO 5-stage filter for the past 2-3 years. It has worked fine. Had to replace the filters cartridges around 2 times or so. Six months ago I added 2 additional large prefilters (blue ones on the left - sediment + carbon). I also changed the RO membrane from the original 50GPD to a 75GPD.
These are the specs of the booster pump:
Everything has been working smoothly until yesterday when the auto-flush valve started shutting on/off very rapidly. See video:
Thinking it was the auto-flush valve I bought a new one, installed it, but it just keeps doing the same. So I removed the sediment cartridges and gave them a good rinse thinking they could be dirty and lowering pressure. Didn't solve anything. Then I swapped the RO membrane for an old 50GDP I had laying around thinking perhaps that could be the reason. I could see the pressure on the gauge rise to nearly 80PSI. I think that's due to the RO membrane being old and exhausted and water having hard time passing through it. Anyway, regardless, again it didn't solve the problem. I checked all valves (high pressure, low pressure) and dismantled them to the last bit to make sure they were in good working other. All good. I don't know what else to look for.
What else should I look for? Advise?
Thanks.
