Reverse Osmosis Membrane Flush Valve - Bulk Reef Supply
I have inspected the O rings but I can do it again.

Should there be any water in the RO canisters?
Try removing that flush valve. Maybe the restrictor is clogged? Normal rate of waste to RO on city water pressure for a single membrane should be around 3-4 gallons of waste to 1 gallon of RO. 2 gallons of waste to 1 gallon of RO seems a bit low on the waste. Worth testing the RO with the restrictor off so you are not forcing too much water through the membrane and pulling TDS with it.Reverse Osmosis Membrane Flush Valve - Bulk Reef Supply

They look ok.. make sure both are going into the small tube at the bottom of the RO housing. It's possible that it's not inserted fully and both o rings are not sealing the end.
Unlikely but if the piece on the inside where the O rings go is cracked then tap water will slip past the O rings into the RO water. I don't think there is a way to test it.Is it possible that the RO canisters are cracked? How do I check for that?
Shirak. I am sorry I do not know how to quote of this site,
Did you run hot water through these membranes at any time? Answer No
As soon as I put them in I noticed a huge problem and then is when I reached out in this thread for help.
At first my lines where crossed, out instead of in, problem with Speactrpure and BRS they are different for in and out.
Looks like a check valve to prevent water from going the wrong direction. I have never used one. I have also never used an auto shut off. I do not see an auto shut off in any of your photos.Mur-lok Elbow Check Valve 1/8" Male NPT x 1/4" Push Connect - G.A. Murdock
What does this valve do, and how do you know if it is working correctly?
Maybe, but you are getting the same results with the old filters and were those also subjected to the reverse flow pressure?Shirak, I wonder if the membranes got damaged by reverse flow?
See thread number 28 for the picture.
