    Product Questions

    Can you use as drinking water or do you have to put a three way in after to RO units and before the DO unit?
    Question by: Arnie Albrecht on Nov 27, 2023, 7:40 AM
    Hi there, thanks for reaching out to us. You can use this system as drinking water as well however you will want that three way valve to bypass the DI portion.

    How many gallons of water should I be able to make before replacement?
    Question by: Deric on Sep 14, 2022, 9:55 PM
    Hey there,
    Thank you for reaching out to us. Unfortunately, too many factors go into that for it to be the same for everyone. Source TDS, Temperature, and pressure can all place a factor. We recommend changing them every 6-9 months and the membrane every 2-3 years. The DI will change color when its time to change.

    Please let me know if you need anything further and take care!
