Questions & Answers


How can I install this system for water dispenser on countertop and to the ice maker line to refrigerator?

Asked by Deb In Florida February 12, 2021

You can go to your local hardware store and get another fitting just like the one Aquasana sent you with your install kit. Install that fitting right on top of the fitting you installed from Aquasana then hook up the service line to your counter top dispenser. Now you have a place for the water line that feeds your filters and the water line that feeds your refrigerator. I hope I made this clear. Glad to help.

How can I get filter replacement for AQ-RO3

Asked by Duds February 2, 2021

You should be able to order them from the website or have them put on Auto-Ship.

I have the Aquasana app, but the percentage of the filter life isn't showing. My Bluetooth is on. Any suggestions? I changed the battery around, thinking the installer had it in wrong. Which way does the battery go?

Asked by Sonata January 23, 2021

Good luck with the bluetooth. I never got it to work. Now as for the filter, I love it and am on the automatic replacement program.

I recently just replaced my filters for the first time in my 3 stage filter system. Very easy to do but now my water pressure from my faucet is very weak. Any ideas? Thanks.

Asked by Billy6698 January 19, 2021

There is a flow restriction valve in each of the canister heads. Why? Because you can unscrew the canister w/o a leak.  You need at least 40 psi of pressure for the water to pass. Sometimes the valves fail. I had to punch out my first filters valve to get it to flow. Now it flows great. But the canister will shoot out water if disconnected. I have to make sure the water is off and the pressure relieved before removing canisters now.  I recommend putting in a particulate filter before the Aquasana filters so the valves don’t get plugged/damaged.

I did it. But it still the same. I think all brand with no tank is the same thing. When you cook ...

Asked by SV January 13, 2021

Asked by Ceros Roman nose January 12, 2021

Hi I just buy 3-Stage last month. Why water have a lot of white dust after cook it?

Asked by SV January 9, 2021

When you hooked it up did you run the water for 15 minutes? You need to do that every time you replace the filters also. Good Luck

Can the faucet head turn from side to side or complete 360 to move it out of the way when doing dishes and things?

Asked by Meredith January 5, 2021

We move ours gently side to side. We are unable to turn it 360 so I don’t know if you can. My mother had one and when she moves it quickly back and forth it tends to loosen.

can i buy the filter system elsewhere and the water for life membership from aquasana?

Asked by chiporter January 5, 2021

Hello, Thank you for contacting us. Yes, you can enroll in our water for life program contact us at 866-662-6885 to help further discuss. Thank you, Aquasana Customer Support

Wanted to love it
First of all this unit will be removed and returned when my plumber comes by. Installation wasn’t easy, needed pliers to install the 1/4 inch outlet hose. Of course one on the cartridges started leaking. Water flavor is good. We wanted to love this unit, but it has to may issues.

The water looks good when I’m not cook it. But after I cook it is too much lime inside the water.

Amazing Product!!!
I absolutely love my Aquasana 3-Stage under counter filter! I've been buying bottled water for years and was looking for a more sustainable and cost friendly solution. Not only is it reasonably priced, but most importantly the water tastes super clean and delicious. It really makes drinking water more frequently easy!

Avoid at All Costs
The first time I attempted to install, a faulty plastic connector ring resulted in the the hose breaking loose and spewing water everywhere, repeatedly. I contacted manufacturer (took 4 tries to get through) who first attempted to charge me $5 to ship replacement t connector kit. Which is crazy considering the problem occurred out of the box. 2 weeks later it finally arrived. Now the water supply line holds, but one of the filter cartridges is leaking despite attempting to adjust it. Also slight leak on other end where hose connects to faucet. I am not by any means ignorant of basic household plumbing, but this product is unreliable and now I have another mess to clean up I am tired of fighting with this product, and it's too much work to get through to customer service. I wish I could still return it, but it sat in my basement too long waiting to be installed. Do not throw your money away on this disaster.

I purchased the standard 3-Stage Filter System
In early November, I purchased the 3-Stage Water Filter system. It took me approximately 1-½ hours from start to finish. Upon completion, I removed the plastic insert to start the system and turned on the water supply. Amazingly, there were no water leaks. I flushed the system for 10 minutes, as required, and afterwards, had my first glass of filtered water. The water was delicious! I couldn't have been more satisfied. I unequivocally recommend the Aquasana filter system I have purchased, to anyone wanting wanting an easy-to-install, inexpensive, under-counter system.
