Questions & Answers

Q:I just replaced my three under sink filters and no water will flow out of the tap.

Answer This Question

A:  I had the same problem. It’s caused by a filter that doesn’t fit right. AQ told me to wash a quarter and then put it underneath the black cartridge to hold it up. It works. Would be nice if they actually fixed the problem though. 

by|Apr 18, 2024

    A:  I had the same issue and called customer support. They had me use the previous filters one-by-one until we identified the problem - the pre-filter they sent was too short and was stopping the water flow. They sent a new pre-filter that arrived in about a week. Might be the same issue for you.

          Overall impression of Aquasana
          So far so good. I installed about 2weeks ago. Was easy enough to install. Working great so far, taste is crisp and clean.

          Great filter system
          The area I live in has municipal water, so I wasn't worried about pathogens or sediment necessarily. However the water treatment plants draw water from the local river, which has had issues with PFAS/PFOA levels due to a local chemical plant. I originally had a water cooler and had 5 gallon jugs delivered from a local company, but it was getting to the point where I would need 9-10 jugs per month. I was tired of lugging them around, not to mention the cost and storage of the containers. I searched for a good under-sink filtration system with a dedicated faucet, specifically one that was ANSI certified for reduction of PFAS. Many of the other products I found state that they are certified, but when I looked on the ANSI website their products/company info was nowhere to be found. Aquasana was one of the only products I found that truly is ANSI certified and you can easily find them on the ANSI website. With the cost of the filtration system itself and the filter changes every 6 months, I would easily save a good chunk of money per year. Shipping was pretty quick, and installation was very straightforward with basic hand tools. The faucet that came with the kit was perfect for what I needed (filling glasses, water bottles, the dogs bowl, etc.) and matched my existing oil rubbed bronze faucet set. Filter installation is a breeze, and I like that you can set up a subscription to have a new set of filters delivered every 6 months. Water quality is outstanding and I like that it filters out the unwanted chemicals without getting rid of the beneficial minerals.

          A few minor tweaks
          It kept leaking when I hung it on the screws Aquasana provided. I found that rotating the green filter slightly and simply putting the filter on contact with the bottom cabinet allowed the water to flow without any leaks. It would save more space to hang it up but I would rather have the product work without leaks at the end of the day.

            No Good Save your Money
            Just installed this filter system today, install was easy but the product is garbage, faucet leaks and water stream is a drizzle. Save you money this product is garbage, we are sending it back. See attached pictures

              Not filtering
              Measuring total dissolved solids (TDS): Aquasana 3-stage: 149 TDS, Unfiltered Water: 118 TDS, PUR water filter: 57 TDS. This new filter is ADDING, not removing contaminants!
              Response from Aquasana Customer SupportMar 2, 2023
              Hello Dave, TDS, or Total Dissolved Solids, is the amount of dissolved minerals and metals present in water. TDS meters tell you the concentration of dissolved minerals and metals, but are not an accurate measurement for contamination. Aquasana products reduce and remove harmful TDS like lead, but selectively retain or replace healthy dissolved solids like calcium, magnesium, and potassium. If you are interested in seeing the change in contaminants only, we recommend using a water test kit that is not testing for TDS. -Aquasana Customer Support
                Clean and refreshing
                The filtered water does taste clean and soothing, very refreshing. The installation was troublesome even for a handyman like myself. Followed the instruction, I had trouble aligning and installing the black filter. When I thought I had it in, it leaks. I came to find out the 2 mating holes in the base unit was 90deg out. Most likely an error at the assembly line. Recommend add to the instructions to check for alignment before installation. See photo. It needs a design change for easier filter replacement. The valve should have been higher to clear the countertop for cleaning.

                Claryum® 3-Stage - Canister defect
                Purchased Claryum® 3-Stage five years ago and it worked great, changing the cartridges on a regular basis. Changed cartridges about 3 months ago and no disruptions around the filter. Then one of the canisters bulged on the bottom and started leaking. Luckily we were close when it started to leak. Concern is long term reliability.

                  Leaks from day 1
                  I was wary of other customer reviews complaining of leaking but we needed an under sink filter for the PFAS in our public water supply. We hired a licensed plumber to install the unit. Despite this, one of the filters is leaking. The plumber made a second visit but was unable to remedy the leaking. It’s a good filter but in a very poor quality product.

                  Leaking filter
                  The system seems nice enough, I can definitely taste a difference in tap water verse filtered water, but the middle filter has been leaking since installed. Customer service was great helping me take care of it, however their remedy did not work so now I am waiting for a replacement to come in. I’m sure I’ll enjoy the filter and it’s a good product, I’m just disappointed with the filter issue from the start. The customer service is what gave the product a chance at redemption.
