    Hi all! I bought an RO system in december gone. The tds from it has gone from 8-13 when it was first being used to 36-63 now. This is surely too high? Im using resin a lot quicker now. I flush it regularly. Are the membranes shot already? Could i be doing something wrong? Any thought appreciated. This WFP business seems to be one expense after another! Seriously considering going traditional!

    Not sure if its relevant but tap water tds is 280-300 so quite high. And i change prefilters every 3 months. My current pre filters have 2 months left.

    Think doug atkinson mentioned in another thread that in some hard water areas membranes can get clogged very quickly without using a water softner.

    Sound to me your membranes might be knackered:(

    I am producing about 200 litres per day, 5 days per week.

    How do I go about softening the water first?

    Yes, its pretty high. From what Ive read its almost as high as it gets.

    And no, I haven't phoned pure freedom. Their service isn't quite what Id hoped for when I bought my kit. Id rather speak to gardiners or x-line.
