YHSublime April 24, 2014 Share April 24, 2014 Hey there AWI, So I went to go make some water tonight with my T3, and I noticed I wasn't getting any pressure on the gauge. No water filling up inside the filter chambers, and a hissing sound coming from my fast flush assembly. The water is pumping (I tested, trust me...) and it's pumping out the drain. No water seems to be coming out the "pure outlet," or through the filters. I took apart all the connections and put them back together again to make sure everything was tightly fitted and sealed. I have not done anything to my RO/DI to make the change. It is mounted on a wall in my closet, and has been there since my last water batch 2 weeks ago. Thoughts?

Air Water and Ice April 25, 2014 Share April 25, 2014 When was the last time filters were replaced? Did you remove all the filters and membrane and try doing our blockage test? Remove all filters and the membrane. 1. Remove all pre-filters and the membrane from the membrane housing and re-install without them. 2. Turn water on the unit … Leave Fast Flush open … Let the water run for 2 minutes then close the Fast Flush. Question: Does water freely flow out the pure water side and the fast flush side? What happens when you close the fast flush? (Drain water should stop momentarily then come out at a slower rate than before.) …. If not, repeat the 15 minute Fast Flush the System. 3. If that test worked … Re-insert the sediment filter & repeat step 2… (You should notice no change in output water pressure) 4. If that test worked … Re-insert the 5 micron carbon filter & repeat step 2… (You may notice a slight reduction in output water pressure) 5. If that test worked … Re-insert the 1 micron carbon filter & repeat step 2 … (You may notice a slight reduction in output water pressure) February 6, 2013 6. If that test worked … Reinsert the membrane & repeat step 2 …You will notice a significant change in water output … the pureRO water should be a small constant tickle … not just a drip every few seconds … but a slow constant stream of pure RO water. NOTE 1: If your RO production is still not good, you may need a new membrane… if your membrane is new then the cause of your problem is insufficient pressure … get a PSI gauge and test your water pressure … you would like to get 60 PSI … During the winter, your water is colder and RO production slows down. A way to fix this cold water issue is to add a hot water connection to your units input water supply which would mix your cold water with hot water (Ideal water temperature is 77 degrees). Or you can add a booster pump. NOTE 2: A rough calculation of reduced water production if you do not have 60PSI or you have cold water that is not 77 degrees: You will lose 2% of you production for every degree less than 77 degrees, and you will lose 2% of your production for every pound of pressure you have less than 60 PSI. So if your water temp is only 70, then you lose 14% of your capacity and if your PSI is only 50, you lose 20% of your capacity. A combined loss of 34% capacity means a 75GPD membrane will only produce 50 GPD. Is the fast flush in the 90 degree position? What water connection are you using from your water source? Sorry to ask so many questions and have so many suggestions but without some prior info I cannot give an explanation as to why your not producing water now. theh2oguru Link to comment Share on other sites More sharing options...
YHSublime April 26, 2014 Author Share April 26, 2014 When was the last time filters were replaced The beginning of January this year, everything except the membrane. I have not tried doing the blockage test, so I did this morning, and here is what happened. I removed all filters and the membrane. I flushed it, and everything worked fine. I added the stage 1 sediment, and no issues. Added the stage 2 carbon, and retried, no issues. Added the stage 3 carbon, no issues. Added the stae 5 DI mixed bed, and no issues. I will note though, that the PSI is 0 every time it produces out the pure line (for each filter test) an only when I "flush" does the PSI increase past 0 to about 40. I added the membrane again, and there was no pure production, and no PSI. The membrane has only been used for a year and a half tops, how do you know when your membrane is finished? I have hard time believing my water pressure just changed (in an apartment, everything else is still fine.) RO/DI is hooked up via an adapter under the sink. I have "set and forget" the RO/DI other than filter changing, and it's strange that all of a sudden it stopped. The fast flush is 90 degrees (closed) and there is 0 PSI (since this problem) when it's like that. When I open the fast flush, the PSI increases to about 40, however, the pure line still does not have any water through it. I hope these jumbled rants and thoughts clear up any questions, thanks for your response! Link to comment Share on other sites More sharing options...
