    Has anyone got a purefreedom RO that understands how it works? Other RO's seem different when flushed compared to this. Tap is at 235-240ppm. The ppm is creeping up on production, is now at 24-25ppm before DI. Month ago it was bout 18-20ppm.

    The pre filters only been in couple of months and membranes bout 10 months flush 3-4 times per week.
    Water pressure good but don't have a gauge.

    I no that the RO works harder with the colder water and pressure can drop at this time of year and production can slow which I don't think it has but if you understand the purefreedom RO on flush the production is about 12-13ppm, flush off it increases to 24-25ppm which is normal production.

    Is the ppm increasing because the water is so cold at this time of year or could there be another issue?

    Hopefully one of the pure freedom guys will come on here and answer that. I have a similar scenario with my Vyair regarding production rates, but I just put it down to water temp being very cold thus membranes not work as effective as in the warmer months.

    Thanks and have done, they are very helpful. Sounds like it could be the membranes on the way out after 10 months! But booster pump could help reduce ppm and increase productivity

    Gray, I have this same unit. In my experience this is quite normal. Mine are exactly the same. Starys off at between 10-15, and over a year it creeps up to 25 or thereabouts, and continues to go up until I eventually buy new membranes. It's one of those costs that needs to be factored in to your costs. As long as you replace the membranes every 3_4 months and flush for 15 mins twice per week there isn't much more you can do.

    IME the cold weather doesn't affect my RO's water tds.
