I actually got it working now. With my new confidence on how RO systems work after watching your videos, I began removing pre-filters to see if they were working properly. Turns out my Carbon Pre-Filter was defective and virtually no water was flowing through it. I replaced it and now everything is working perfectly with a huge increase in the water flow (before it was just drops) When all other likely fixes failed, I looked at the unlikely ones. Thanks for the help - it is much appreciated.
Thank you very much for making this video. We were going to replace the filters today. I found this video last night. We now know it is the bladder in the tank. You saved us time, money and frustration.
Thanks, exactly the info I needed! I had the super slow flow after about 1-2 years after the installation. I disassembled the valve first and then the whole system wasting 2 hours of my time... After watching your videoI gave a few pumps into the tank and the system started to work fine again.! 2 min.!:)
Thank you for the lesson. I'm going to install one of these soon and I was clueless about how they operate. It is nice to have some idea of how they work. Very good presentation.
Aqua-man has been around for decades and also member of the Justice League of America alongside Superman, Batman, Wonder Woman. Not sure why he gave up super strength, durability, control over sea life, exceptional swimming ability, ability to breathe underwater to become a plumber (still has durability). However, I liked his description of the RO system particularly constant drain of water is due to faulty ASO valve. Many other YT videos don't really mention this.
Thank you,i've had a culligan ro system for 18 years and i change my filters myself every year and main membrane filter every 3 to 5 years and i did not know about the aso valve,but mine is fine because the water does not continuosly run.I appreciate your video,i love learning because knowing is power.Thank You very much!
Great video I just wish you had more troubleshooting vids. These are two problems but based on the comments there's quite a few more issues out there. Including mine which is the tank isn't filling with water.. I've seen other websites that mention this problem and say check this and check that. They're not clear like this vid was.

Thank you for posting this. Step number one should be the simplest which is check tank pressure, I can't tell you the amount of aggravation I have gone through trying to get my system to work again.
Awesome, awesome video! Thank you very much for this information. You not only provided abundant insight into the problem I am experiencing, but you also helped me to understand the physics of the RO system much better - all with perfect clarity. Please keep up the fantastic work!
Better. RO systems love more pressure! Though with that much of an increase you will need to be certain you are taking good care of your O-rings. They will obviously be stressed much more under the greater pressure. Having said that, you will get much better production rates and higher TDS rejection.
THANK YOU This has been very helpful in some cases but I'm still having an issue. PLEASE HELP!!! I just changed all of the filters and the membrane but when I turn on the water there is no brine water coming out of the black tube nor can I flush the membrane even after I remove flow restrictor. I've checked and cleaned the membrane tube to make sure there was no clogging but it didn't help. UGH in tears!! Thank you.
What model is your system? The tank should have 30-35psi when full. If it doesn't then something is wrong with the tank. When you say shut off diaphragm are you referring to the ASO (automatic shut off) valve?
If you are certain the tank is empty and not receiving any water, then the system must not be producing any water. Make sure the tank is empty by opening the faucet and draining any remaining pressure, then remove the water line that feeds the tank. Put that water line in a bucket and see if it is producing any water. If not, then something is wrong with the system. Maybe a clogged filter or membrane, or possibly the ASO valve is defective. Is the system making a continuous noise?
What if in the morning, after zero use of the faucet, I get a trickle, and the tank is not even full,but feels empty? Why is the tank not filling up with water? Yes, all water valves are turned on fully.
a defective tank is not the only posible issue with low presure sometimes the filters are clogged and needs to be changed or there might be mineral buildup in the inlet line
We replaced our tank, but it does not fill. We've followed the steps to re-pressurize the tank, installed new filters, have checked to see that water is entering the system. We get approximately 30 ounces of water than nothing. Suggestions?
Sir, I have a small amount of water coming out of the drain line Hint, 1- the pressure of the water pump is more than 10 bar 2- I replaced all the filters and still have the same problem.
i putted new filters and after i get bad taste. i let the water to run for an hour or more and I've got better taste before with the old filters. i changed the filters nothing i bought new one's better than before but not good as before what else shall i do? the pipes is on the right place
Wow, you provided great information in the video! I have a Watts ZRO-4 and the Recirculation Pump seized. Then modified it with a ASO valve, and check valve between the membrane and GAC filter. The task piqued my interests, now I'm considering adding another housing at the end of pre-filters. E.g. a 5 micron coconut shell carbon cartridge, or a VOC Filter block. I just wonder if doing all that is unnecessary, considering the membrane does it too. Hope you can help. Thanks for the helpful video!
@PlasmaEnthusiast Sorry, but you need the tank for storage. Depending on the GPD rating of your system it is only producing a couple of ounces of water per minute (hence the need for a reservoir tank). Did you check the filters? What was the result of your investigation?
when we filter out 80 percent or more particulates including minerals from water and then drink this water, i have read the water then absorbs almost all particles including minerals that in comes in contact with in the stomache, in effect acting like a sponge, therefore should we first treat the water with minerals before drinking? maybe even mix the water with fruit and let stand for an hour first?
I have a similar problem, I replaced all of my filters in my Hydrotech system and the tank does not fill. I emptied and reset the pressure in my tank to 7 psi. I replaced my restrictor line and I even replaced my check valve yesterday and it still won't fill. The unit is producing clean water and drain water when I disconnect them. It almost seems like the filtered water doesnt have adequate pressure to fill the tank. The driain line runs continuously even though the tank doesnt fill. HELP !
excellent video. i have a watts premier RO system from costco. everything seems to be ok, except i get this vibrating noise (humming noise) that is quite loud at night. at first i thought maybe the tank was too full, which we drain out the water to drink and let it refill, but it still makes that noise after a while later. what could be the cause? please help.
Excellent video. It didn't address my questions, but it's very helpful for understanding how reverse osmosis systems work. I have two questions. First, unlike the problem depicted in the video (continuous discharge), my system never discharges any more. Second, after more research, I don't think I need reverse osmosis anyway. I wonder if my water is still being filtered in four stages and if so, is this as good as a high-end four-stage non-RO filtration system, or should I ditch the system I have and replace it?
RO or Distillation are the ONLY methods that can achieve ideal drinking water- under 50ppm of Total Dissolved Solids. If the new equipment can bring your water to less than 50ppm then yes, this is the standard for ideal drinking water. It can be measured using a TDS Meter.

You Sir are very informative and have a gift of communicating with in- depth explanation. Thank you for educational video. I now know I need a tank and possibly a ASO valve. Hissing is only at certain times. I will change the tank and if I hear the ASO not shutting off I will replace. I just installed a PRV and had to reduce to 55 PSI from 85 PSI for Water distribution system for entire house. I believe the previous high pressure trashed the tank and possibly the ASO Valve. Question, before I replace either do you know what the PSI rating for tank and ASO Valve?
Thanks for this. You're good at explaining. I have a 10" filter with a 10" housing, but the filter became moldy because I couldn't screw it shut, it didn't go all the way down to the buttom(rounded off housing at the buttom, two different manufacturors. How is the water supposed to flow when the filter is inside the housing?
I replaced the polishing filter because it had been a year, now my tank will not fill up and my waste water is running down the drain, is my aso valve bad.
Great explanation, thanks! We have a GE RO system and no water is coming at all. We know that what happened to it was that the water was left on here at the acreage and the well was run dry, which clogged up everything in the RO system and we figured it was just the filters that needed changing so we bought new ones and tried to install but there isn't any water coming through at all. After watching the video, can you tell me what you think might have happened? Do I need a new tank also?
Here are a few things to consider. Are you absolutely sure you have the correct O-rings? Are they in PERFECT condition? Have you tried to seal the housing with NO filter installed? It's possible the filter is not allowing the housing to close all the way. Are you sure the housing sump is not cracked?
I have a WHER25 RO, I am getting a leak from the faucet side of the system on a very irregular basis. It will be ok for a week, or longer with no leak, then there is water leaking onto the kitchen floor. Like a big squrit of water then it stops. Help appreciated. Fred Keeler
Hello. Today we changed all our filters in the system and now we have a priblem:water not getting in to the tank. If I turn the water on its licking non stop. I mean if it was the tank water it would stop running after a few minutes when tank would get ermpty, right? But it's won't stop running. I'm assuming that water won't go to the tasnk and goes straight to the faucet. How I can fix This?
No bodys been able to fix my problem. My tank will not fill with water. The tank has 8 pounds of air empty. I've drained all water out of tank. I've let the air out of the tank and refilled it to 8 pounds. Still no watwr in the tank. Watwr flows to faucet for 20 seconds and stops because no watwr is going into tank?
@1IIIIIIIIII1 No. Reverse Osmosis does not use any chemical in the purifying process. In very basic terms, the water is being pushed through a semi-permeable membrane that only allows extremely small molecules through. 95% rejection of TDS (total dissolved solids) is typical. RO water is extremely pure water.
Hi, I just replaced pre and post filters and membrane on my GE profile RO. If i remove the membrane I get great flow. If I leave it on, I get the “fill a half cup” problem.Very little water trickles from the filters to the tank, so it’s not the tank. Do you think it was a bad membrane?
our system is not working. Water is flowing up until the reverse osmosis membrane. We just changed the membrane and have not idea what could be the issue.
@fadifanous That is highly unusual. I suspect either your system is incorrectly installed/configured or the polishing filter (last filter after the membrane), or the membrane itself is defective. is the membrane a chlorine tolerant membrane, and if not (probably isn't) are you using a carbon pre-filter to remove chlorine, and are you being faithful to change it on schedule. Chlorine will burn most membranes if not protected by a carbon filter.
Todd Surdick Good Question! Yes the pressure inside of the tank will decrease when the tank is not completely full.Please let us know if you have any other questions!
you don't "absolutely" have a bad aso valve if you're constantly getting drain water, you could be missing your flow restrictor on your drain line, seen it happen plenty of times when people go to change their filters
Only change your flow restrictor when you change the reverse osmosis membrane cartridge. That's only once ever few years. My last one went for six years before it began to slow down. Not bad!
My tank is full and I don't get any reading from the valve. I can usually get one large glass of water before it turns into a trickle. That means it's the tank, right? I guess I gotta get a new tank.
***** Hello Wen Chen, The leaking sounds more like it could be a crack in the tank/valve or a tubing issue. Although some leaks may indeed be caused by pressure. I would recommend checking all the fittings/valves and all of the water lines to verify there is no cracks that could be causing the leaking.If you have any other questions please call our customer service department and we would be happy to trouble shoot with you. Our phone number is 888-801-7873. We are open Monday - Friday 7AM-7PM CST. Thank you WaterFilters.NET
Hey I had a friend who originally installed my system rerun the black line because it was run too tight and had a kink in it that was causing constant gurgling. Once he reran that line the gurgling stopped but before I suggested the problem was that kink he had messed around all crazy with the psi of the tank exactly like you mentioned not to do. Since the repair was done and he had messed with the tank psi (rather aggressively) the tank has not refilled. Is still disperses water but the tank is clearly empty or not fully filling up. Is this the sign of a broken bladder? Do I need to replace the tank?
man i wish someone would make a portable reverse osmosis system because i cant be drilling a few holes in my rink just to install these monster filter cartridges.
logically, this is a "yes u can" answer; problems are a) hooking it up effectively, to do so....&......b) you will go thru filters & membranes that much faster, and your water quality at any given time may be questionable/unsafe/not up to "standard" for an RO systems goal in the first place.

@aquamanwisdom you assume to much, I read about these issues regarding 'water fasting' with RO. I just thought you might know of/ or sell mineral drops with your machines or perhaps had other suggestions to re-mineralise the water after purifying. Millions of people fast all over the world ,so I thought perhaps you might have knowledge in this sphere. Anyway, definitely the wrong place to ask at the wrong time, i was just interested in your channel looks good , have fun.
