The trick is to get the air out of each filter valve. Make sure you close the T water valve first so water to the filter is CUT OFF. And then perform the following. Take out the last two filters and keep the filter closest to the “in” pipe intact. Then slowly open the T valve and let water run out. Once it runs out evenly, close the Tvalve and perform the same with the next two filters.
Thank you. I didn’t have a washer so I took a plastic tile spacer and cut it flat and put it in the bottom of the green pre filter. Now I think we have more power than before. Thanks for the help!
Thanks for this. Just installed the 5300 to replace my older lower flow 5200. Flow was dismal. A washer in the bottom of the green filter fixed the issue and it's now flowing like a champ.
I also had the low water pressure problem when I put in new filters and put a garden hose gasket at the bottom of the first filter and it fixed the problem. Thanks for the information so much!
I just wanted to say thanks for the info. I purchased 3 flat nylon washers (1-1/8 x .54 x 1/8) and put one in the bottom of each filter and fix the low flow problem. I also used some plumber's silicone and it took care of leaks!
Thank you to this randomly super helpful comment section! My flow was fine the first day after installation then literally nothing the second day. Turning each filter a bit allowed some flow but also caused leaking. Then I took each filter off, opened the canister, took the cartidge out then seated it firmly back in (pushing up the spring-loaded valve), then screwed each canister closed tight. Back to great flow! I didn't even need the washers but if it happens again I'll do that.
Ok my genius son found the solution. Unscrew the first canister, that's the one that has the low pressure issue. Put three nylon washers on the bottom under the filter, reinstall the filter. The washers will put enough pressure on the valve on the top of the cartridge to allow you perfect pressure.
Thanks this Worked for mine ! I put 3 filters on the bottom of the cartridge and screwed it in while holding it upside down to keep them in place. I was having 0 flow after I replaced my cartridges , it would only work when the cartridge was half tightened in the manifold. Btw , it was the first green one that caused the issue.
Ditto here, after replacing the 3 filter cartridges in my 5300 undersink setup there was low flow then no flow. Put 3 garden hose washers side by side in the bottom of each housing, set the filter cartridge on top of the washers, and then screwed the housing top back on. Now I have at least 3 times the flow I have ever had. Yay!
I had no pressure after changing the filters. I am lucky I found this reply chain and used a washer as a workaround. I agree with the comments about poor quality control for the manufacture of the filters. I also suspect the company is aware but chooses to be discreet since, like many companies, it's all about sales. More importantly, one has to wonder about the quality control for the filters water purifying contents. I am sure the company knows that we have no way to truly determine if the minerals and elements ate precise.
I ran into the same problem. I was reading the comments and turned the green filter 1/4 turn. And it worked perfectly fine after doing that. Good luck guys.
Two hours of frustration, several youtube searches and $1.39 later the filter works fine. The three hose washers worked perfectly. My problem was not the green pre-filter, but the black middle one.
Adding my experience that the solution posted by Michael Blaney worked for me as well. Problem is clearly due to poor mfg tolerance of filter causing it to not properly seat and fully push valve at top of canister. (In my case it was the black/green first filter but I suppose this could happen to any of the three.) The key is to find a shim material to add to the bottom of the canister that is bio-compatible enough to sit in there for 6 months to year. Metal seems like a bad idea since it would rust. Nylon washers as originally suggested are good but you might not have any lying around. I used a folded up plastic sandwich bag, new from the container so that it is clean. Worked perfectly.
Dont know where Micheal Blaney is but all I needed to do was add a plastic cap from a water bottle to the bottom of my green filter and no more low flow problems. Thanks to everyone who commented under this video.
Edit: Leaks, leaks, leaks. Unfortunately what I did originally below didn't work for long. It started leaking within a few months. Aquasana is selling a defectively designed product. I wasted so much time with this company. Both on the phone and messing with leaking filters. If the filter sump needs to be loosened to flow, the unit is defective. They can't be overtightened. They can only make 1/4 turn before the hit a tab that prevents that. First they sent replacement filters. Still leaked. Second they sent replacement sump bottoms, but not the cap where the leak was. Still leaked. Finally they were going to send only a new manifold but I insisted they replace all of it, including the sump tops as well. They sent an entire new unit, including filters. Worked ok for 3 months then started leaking at the top of the pre-filter where it meets the manifold. I'd recommend staying far away from Aquasana and buying an under-sink water filter brand that works and doesn't leak. Original comment: I had the same problem with a low flow rate immediately after I installed this Aquasana system. The solution from Aquasana was to open the filtered water faucet, then loosen the green pre-filter slightly-less than 1/4 turn. The water started flowing faster immediately. They said the filter was "overtightened" but I never forced anything, I only turned in each filter all the way. This information is nowhere in the installation instructions. The green pre-filter has to be adjusted just so to get the max flow. If it's loosened too much it will start to flow less. Aquasana should clearly say this in the instructions. Instead it only says "Ensure that the sump is fully attached and locked in."
@@LarryGottschalk Sure! They were pretty quick on the phone and it was the first thing they suggested. Edit: Unit started leaking and I spent way too much time on the phone with them. Also I wasted a ton of time dealing with replacing parts repeatedly with no success.
Great advice!! It immediately started with better flow 🙌🏽🙌🏽 It’s leaking from the big tank but I’ll try Teflon or the silicone the other comments are suggesting, thanks!
I called aquasana for the same issue. She had me move the lid from the red filter on the black filter and vice-versa. Filters stayed the same, just the lids. 100% fixed the issue. Surprised I didn't think of that :) No washers, quarters or anything goofy like that.
I just installed this system and I wish I didn't. Same exact issue . I do wish I saw this video before purchasing. Now I'm going to send it back after having discussion with aquasana on Monday. I had a zero water flow upon first installing the system. I inspected the filters and put them back and then I had a very limited flow. I inspected again and flow increased slightly. I found this video and used rings that remain on a large mouth plastic bottle after removing the cap to prop up each filter. Now the flow is very good but I'm not going to keep the janky system, when a new system should be designed well enough to not have issues. These filters should screw into the bottom of the cap. This issue would be solved for everyone permanently. You should not rely on manufacturing tolerance of the filter length and cup length for system reliability. Avoid this product completely.
3 rubber washers under the green prefilter solved my issue as well...I didnt even realize our flow was that bad now its higher than I can remember, had ours going on 3 years now.
I got dripping water after replacing the filters. I took out the rubber rings from the old filters and but them at the bottom of the pre-filter (black). Flow is now back to normal.
Michael Blaney you do have genius son. I put plastic 2 mm part at the bottom of the first (black) filter and it fixed the problem. It runs like champ now. Thank you for the comment. It is manufactures faulty design.
Placing a nickel at the bottom of the primary filter case (black filter for 5300 model) also works. A metal washer or coin at the bottom prevents the filter from sliding down in the case.
Like everyone here, I had the same issue with very limited flow upon install and wasted hours taking this/filters apart inside and out; One nickle added to the bottom of the green filter worked like charm and max flow is happening! Still upset however.
After replacing filters, good flow for a day and then a dribble to no flow. I decided on the easiest approach to the no flow issue (aside from junking the whole unit and going with a new manufacturer). Loosened the pre-filter VERY slightly (maybe less than an 1/8 of a turn). Now, full flow and no leaks yet. Will update if necessary. By the way, don't forget the food grade (sanitary) silicone lubricant on the cover gasket to prevent leaking. I apply it every filter change.
Thanks for all the tips! My water was flowing real slow for a couple days after changing the cartridges. Never had a problem after changing filters every 6 mos. for the past 3 years or so! This morning, it stopped completely! So, I got some quarters, washed and rinsed them and started putting them in the bottom of the cartridges. Of course the last one I tried, the black one, water pressure is better than it has ever been! Shim the black cartridge first! 😅Wonder if quarters corrode? I'll probably go to the local Ace and get some plastic washers.
Thanks everyone, I just took a plastic container and cut a circle and folded it in half and put it under each filter and it solved the low flow problem. I would have never figured it out
I tried adding garden hose washers to all cartridges, and ended up making a 1/32" rubber gasket to add additional thickness to the garden hose washer on the pre-filter. I am back to full flow and have no leaks. This is ridiculous to be forced to cobble up a fix to replacement filters that cost me so much money. Pitiful quality control.
I do believe I have a solution. At the top of each filter housing there are two ports (inflow and outflow) and if you notice, the center port (outflow) is spring-loaded. This feature prevents water flow if there is no filter cartridge, though, however, if the filter cartridge does not provide enough pressure upon this spring-loaded mechanism then you will only get a reduced flow. First off, push the cartridge into the top seating before putting the canister together, and if this does not work, drop a garden hose washer into the bottom of the cartridge housing. But do this after you have tried seating the cartridge prior to putting the canister together since the tolerances are tight, noting that one out of the three filter housings leaked with the garden washer in the bottom. Nonetheless I'm back to a 0.75 gpm flow on 50 psi water pressure. Hope this helps. And as a proper note, my 5300 is approaching three years old and of course, normal wear will expand the tolerances. Hence next time my filters are due for a change I'll purchase the two-stage for $100 (really do not need the pre-filter stage since I have municipal water) and have no complaints considering this system is perhaps the most effective on the market for the price. Edit made April 5, 2019: Apologies, but I failed to mention that one should start with the sediment filter first and then try every filter individually after that. So do the sediment first and if not successful, add a washer to the next while keeping the washer in the sediment housing. And if that works, for example, remove the washer from the sediment and see if the flow holds, though it may not since both filter housing may need a washer. As to the many comment expressing leaks, try a bit of plumber's silicone. Only a very thin coat on the O-rings, using a Q-tip, works wonders. Cheers
This appears to have worked. I added a washer to the "black" filter first. There was no change. Then I added a washer to the "red" filter, and it worked perfectly. My filter is also about 2 years old, and it always worked fine. I think you are correct that the canisters expanded slightly thereby affecting the pressure. Thanks for the help.
Agreed explanation here and the solution. Nice work guys. Btw the garden hose washer goes inside the filter canister at the very bottom. It serves as a spacer for the filter to open up the release valve fully. You can use anything, just make sure it doesn't rust or deteriorate. Like a set of stainless steel washers.
I had the same problem and call the company. And believe it or not they said to actually switch the green lid with the red lid and then put them back together and try that. So if that doesn't work switch the green cap with the yellow cap and that should get rid of the air bubbles. I switched the green with the red and actually worked, but it's only been a few hours so-we'll see how long it lasts but you can give it a try
We had a great flow after exchanging the filters, very slow, and air bubbles. We tried all the solutions that are listed here, including the "son genius" one... nothing!
I had the same low flow problems when I replaced the filters tonight for the first time since I bought the unit a year ago. Tried garden hose washer - flow was great but housing leaked slowly (tried this in the prefilter first). Removed it and inserted stainless steel 5/16" flat washer. Flow was normal and no leaks. Never had to touch the two final filters. Obviously Aquasana has variance in their manufacturing process - you would think for $70 per set of replacement filters they could do a better job of quality control. Annoying.
New filters slowed flow way down. I put a 1 1/4" fender washer in the filter housing, under first filter, worked like a charm. Better flow than ever. Thanks for the tip.
I had no flow after replacing all 3 filters. I only had to add a nickel to the bottom of the green filter. ( Only figured it out after reading this thread,)
Great comments- saved my install! Had to do the same thing - install a washer under filter of green canister. After that, water started to flow. Thanks everyone!
For these filters without a storage tank need higher water pressure. Upwards of 80psi or more. 50 psi just can't push the water through the filters. You can add a small tank under your sink and that will help.
Thanks for the suggestion Mark, but that is incorrect. The original unit was flowing at 0.15 gpm (repeated measurements, 3 sets of filters) which is 20% of Aquasana's advertised flow rate. With the replacement system, repeated measurements are 0.66 gpm which is 92% of the advertised rate. The original unit was simply a defective system, and it works fine now (no supplemental tank, standard city-fed water pressure) and has been for the last 9 months. No thanks to Aquasana - would have been nice to have some customer service. ANY customer service.
Interesting. But I still stand by my suggestion. If you want a larger reserve of higher gpm of filtered water installing a tank tee’d into the filters faucet supply line . A tank like used in reverse osmosis.

I had a lot worse situation. No water coming out of the faucet at all after I replaced filters. After I read one of the comment(by Deborah) :she inserted water hose washer at the bottom of the filter: I did exactly same for all three, guess what, water flows like fire hose... big surprise, manufacturers defect.
I have recently installed the same water filter and it has the same slow flow rate as yours. Have you ever figured out how to fix it? The only difference on mine is I have a water hammer arrestor installed on the cold water line.
Had to replace it. Copy/paste from my other reply here: Tthe solution was a complete system replacement. Aquasana was initially responsive to my inquiry about the problem, however after I posted this video and sent them the link they never again replied or even responded to any of my calls/messages or emails. Completely ignored every further attempt to contact them. Extraordinarily poor customer service. The final "solution" was to file a complaint with Amazon and return the entire system. They sent me a complete new Aquasana system (the exact same item) and it works as-advertised. I'm not sure which element was the problem, though after installing the complete replacement system, it has worked well. Almost exactly 7 months on, it's still good. I'm pretty torn about Aquasana - though it works well now, I'm really unhappy that they simply stopped replying to my inquires for help in solving the defective system that I received initially. Last note: they did send me a set of replacement filters before I took this video, but it didn't do anything to fix the useless flow rate. Not sure I could recommend them as a company, and if you're not in the position to get a replacement system from the place you purchased from, then I definitely wouldn't recommend. Good luck sorting it out.
Oof, haven't heard of that. I replaced our filters a few days ago and the water is still aerated and flows at a much slower rate than the previous set. Everyone in the house has commented on it. It has, however, improved over the couple of days since I first installed them. I noticed that the instructions have been changed a bit and I followed them to the letter. Primarily, no tools (incl the one that was sent with the kit, originally) just hand-tightening only, which seems reasonable. I think if you want better quality, you need to move away from this consumer-level system to a more professional setup from another company.
Aquasana customer service sucks ass so I stopped using them, after the second filter replacement all filter casings leaked all over, they didn’t replace everything just 2 of the casings and they charged me shipping to do so, then my replacement filters grew purple spores that turned brown, I had to call my credit card company to get a charge back on those as well as they wanted to charge me shipping again to send those back.

You guys need to use marine grade washers. Like the ones they use on boats and you will be good. Remmeber to put it on the green filter since that's the problem child.
Chinise made product very expensive and quality are not best even when someone replace filter problem keep going bcz inside systems get plastic debris then clogged and stop entire water flow
Yes I found that loosening fixed the issue. You can actually see the container bend and form a lip if you screw it too tight. Definitely only use your hands, no tools.
Do not buy AquaSana - I've had continuous leaking problems when I install new filters and they will not send new parts after one year. If you have to pay a handyman or plumber to go through this process it may cost you hundreds of dollars - so for non do it your selfers it can be costly. For do it your selfers - what is your time worth to spend half a day or more messing with this?? What should be an easy half hour filter replacement job turns into several hours and trip to the hardware store and water cleanup and phone calls to AquaSana.
All I did was reinstall all the filters into the sumps, and run the tap for 10 mins per manufacturers instructions, and it seems to have fixed my low flow rate completely..I think it’s just air trapped in the filter that needs purged
The trick is to get the air out of each filter valve. Make sure you close the T water valve first so water to the filter is CUT OFF. And then perform the following. Take out the last two filters and keep the filter closest to the “in” pipe intact. Then slowly open the T valve and let water run out.

Loosening the Green filter solved the problem for me. Thank you so much for help on this comments section!
Thank you, Genius Son!! After one hour of trying on my own to get the system to work, I turned to TH-cam and found these comments. Incredible!
I ran into the same problem. I was reading the comments and turned the green filter 1/4 turn. And it worked perfectly fine after doing that. Good luck guys.
So you loosen it by 1/4 or tighten
Thanks! It works for me. Just loose it a bit.
Weird that this was so effective. Loosen a 1/4 turn clockwise and it comes out much better.
Just did this and the water completely shut off.
@@jrmmudloverI’ve done this and it finally comes out great- but there’s some leakage from it. Any tips?

My filter is also about 2 years old, and it always worked fine. I think you are correct that the canisters expanded slightly thereby affecting the pressure. Thanks for the help.
Worked perfectly for me, flow is faster than ever now. Thanks for the information.
@@mferr1 Where exactly did you put the washer?
Agreed explanation here and the solution. Nice work guys.
Btw the garden hose washer goes inside the filter canister at the very bottom. It serves as a spacer for the filter to open up the release valve fully. You can use anything, just make sure it doesn't rust or deteriorate. Like a set of stainless steel washers.
I had the same problem and call the company. And believe it or not they said to actually switch the green lid with the red lid and then put them back together and try that. So if that doesn't work switch the green cap with the yellow cap and that should get rid of the air bubbles. I switched the green with the red and actually worked, but it's only been a few hours so-we'll see how long it lasts but you can give it a try
Thank you! I just tried it and it worked. No leaks, no air purges. I appreciate it😊
We had a great flow after exchanging the filters, very slow, and air bubbles. We tried all the solutions that are listed here, including the "son genius" one... nothing!
Then I suggest politely you don't know what you're doing
I had the same low flow problems when I replaced the filters tonight for the first time since I bought the unit a year ago. Tried garden hose washer - flow was great but housing leaked slowly (tried this in the prefilter first). Removed it and inserted stainless steel 5/16" flat washer. Flow was normal and no leaks. Never had to touch the two final filters. Obviously Aquasana has variance in their manufacturing process - you would think for $70 per set of replacement filters they could do a better job of quality control. Annoying.
New filters slowed flow way down. I put a 1 1/4" fender washer in the filter housing, under first filter, worked like a charm. Better flow than ever. Thanks for the tip.
@@purusarthadasa3750 hmmm - might just have to try that . . .
Yea you are right!
I had no flow after replacing all 3 filters. I only had to add a nickel to the bottom of the green filter. ( Only figured it out after reading this thread,)
Great comments- saved my install! Had to do the same thing - install a washer under filter of green canister. After that, water started to flow. Thanks everyone!
For these filters without a storage tank need higher water pressure. Upwards of 80psi or more. 50 psi just can't push the water through the filters. You can add a small tank under your sink and that will help.
Thanks for the suggestion Mark, but that is incorrect. The original unit was flowing at 0.15 gpm (repeated measurements, 3 sets of filters) which is 20% of Aquasana's advertised flow rate. With the replacement system, repeated measurements are 0.66 gpm which is 92% of the advertised rate. The original unit was simply a defective system, and it works fine now (no supplemental tank, standard city-fed water pressure) and has been for the last 9 months. No thanks to Aquasana - would have been nice to have some customer service. ANY customer service.
Interesting. But I still stand by my suggestion. If you want a larger reserve of higher gpm of filtered water installing a tank tee’d into the filters faucet supply line . A tank like used in reverse osmosis.

After 3-4 days the air has cleared and the flow seems to be good!
I had a lot worse situation. No water coming out of the faucet at all after I replaced filters. After I read one of the comment(by Deborah) :she inserted water hose washer at the bottom of the filter: I did exactly same for all three, guess what, water flows like fire hose... big surprise, manufacturers defect.
I have recently installed the same water filter and it has the same slow flow rate as yours. Have you ever figured out how to fix it?
The only difference on mine is I have a water hammer arrestor installed on the cold water line.
Had to replace it. Copy/paste from my other reply here:
Tthe solution was a complete system replacement. Aquasana was initially responsive to my inquiry about the problem, however after I posted this video and sent them the link they never again replied or even responded to any of my calls/messages or emails. Completely ignored every further attempt to contact them. Extraordinarily poor customer service.
The final "solution" was to file a complaint with Amazon and return the entire system. They sent me a complete new Aquasana system (the exact same item) and it works as-advertised. I'm not sure which element was the problem, though after installing the complete replacement system, it has worked well.
Almost exactly 7 months on, it's still good. I'm pretty torn about Aquasana - though it works well now, I'm really unhappy that they simply stopped replying to my inquires for help in solving the defective system that I received initially.
Last note: they did send me a set of replacement filters before I took this video, but it didn't do anything to fix the useless flow rate. Not sure I could recommend them as a company, and if you're not in the position to get a replacement system from the place you purchased from, then I definitely wouldn't recommend.
Good luck sorting it out.
I put a silver quarter of the USA on the bottom of the filter and everything worked out.
What if flow just stops? Woke up this morning and nothing. Water in regular faucet totally normal. Help
Oof, haven't heard of that. I replaced our filters a few days ago and the water is still aerated and flows at a much slower rate than the previous set. Everyone in the house has commented on it. It has, however, improved over the couple of days since I first installed them. I noticed that the instructions have been changed a bit and I followed them to the letter. Primarily, no tools (incl the one that was sent with the kit, originally) just hand-tightening only, which seems reasonable. I think if you want better quality, you need to move away from this consumer-level system to a more professional setup from another company.
Aquasana customer service sucks ass so I stopped using them, after the second filter replacement all filter casings leaked all over, they didn’t replace everything just 2 of the casings and they charged me shipping to do so, then my replacement filters grew purple spores that turned brown, I had to call my credit card company to get a charge back on those as well as they wanted to charge me shipping again to send those back.
Any solutions?

You guys need to use marine grade washers. Like the ones they use on boats and you will be good. Remmeber to put it on the green filter since that's the problem child.
Chinise made product very expensive and quality are not best even when someone replace filter problem keep going bcz inside systems get plastic debris then clogged and stop entire water flow
water flow sucks! take forever to fill a 12oz glass
My mine leaks after half a year and replacement of the filters. Tightening makes worse. Good idea but a Badly manufactured product! Never buy!
Not far from recommending this advice. Haven't had any leaks though.
Yes I found that loosening fixed the issue. You can actually see the container bend and form a lip if you screw it too tight. Definitely only use your hands, no tools.
Do not buy AquaSana - I've had continuous leaking problems when I install new filters and they will not send new parts after one year.
If you have to pay a handyman or plumber to go through this process it may cost you hundreds of dollars - so for non do it your selfers it can be costly. For do it your selfers - what is your time worth to spend half a day or more messing with this??
What should be an easy half hour filter replacement job turns into several hours and trip to the hardware store and water cleanup and phone calls to AquaSana.
All I did was reinstall all the filters into the sumps, and run the tap for 10 mins per manufacturers instructions, and it seems to have fixed my low flow rate completely..I think it’s just air trapped in the filter that needs purged
