    What to do if my Aquasana AQ-SFRO has slow flow?

      John WebsterAug 5, 2025
      If you're experiencing slow water flow from your Aquasana Water Filtration Systems, first ensure water is flowing from the faucet. If it is, close the faucet and check the pressure again after one hour. If it’s been over six months since your last filter change, consider replacing the filters.

    How to fix a water leak or drip in my Aquasana AQ-SFRO?
    • N
      Nicole DiazAug 21, 2025
      A leak in your Aquasana Water Filtration System can stem from a loose connection at the inlet/outlet. To address this, turn off the cold water valve beneath the sink. Then, depressurize the system by opening the faucet, which releases any trapped water. Also, ensure the color-coded tubing is correctly placed, cut tubing straight (not at an angle), and is fully inserted into the manifold. After reconnecting, turn the water back on and check for leaks. Confirm cartridges are locked. If leaking persists, shut off the cold water and contact Customer Support.
