Ask a Question
  • What is the finished water to waste water ratio?

    The ratio is 1:3.

  • I bought the Aquasure Premier Advanced Reverse Osmosis Drinking Water System - 75 GPD . I was wondering if I could it hook up to my refrigerator water / ice-maker . I have a 1/2\"CPVC line going to it now. Could I get a T-connector for the waterline and how would it connect to the 1/2\" CPVC Line. Thanks

    It would be hard to say, but we do sell a extra output kit part number (AP-XOUTPUT) that allows the system to be connected to an icemaker kit on the fridge. It also comes with at 25' tubing to help route to the fridge.

  • Can I purchase the replacement filter on Amazon or other places or I can only buy them on the website?

    We do sell our replacement filter and system through major online e-tailers such as Amazon and eBay. We also offer both Amazon pay and Paypal during our checkout if you prefer using those payment methods.

  • I have just installed the R/O system and the water coming out of the faucet has tiny bubbles that go away after about 15 sec, Is this normal? Water tastes great.

    Yes this is simply aeration in the line

  • I have AS-PR75A unit. How can I get a safety disc replacement. Part no. not list in parts list.

    Thanks for the question. If you need additional safety discs for your RO system please find them here in the link below.

  • I have a AS-PR75A unit and I notice that water runs in the black tube into the drain long after the faucet is turn off. How long should the water drain and why does it continue after the faucet is turned off?

    Our system perfoms on a 3:1 gallon ratio. Once you've poured water through your faucet, the system will run water through the filtration to refill the reserve tank. During this time, there are 3 gallons of unfilted water draining for every 1 gallon of purified water produced.

  • What is the capacity of the filters?

    The system/filters are cabable of producing 75 Gallons Per Day. 

    RO Filter Replacement Time Frame
    • Pre-Stage Filters ~ The pre-sediment and the pre carbon: Replace every 6 to 12 months (Private well water source may need to replace pre-filters sooner than 12 months due to heavy sediments and other particulates.)

    • RO-Membrane and Post Carbon: Replace every 2 years (Private well water source may need to replace membrane sooner than 2 year due to lower source water quality)
