    Hi I have just got round to fitting my 4021 ro system and just want to check im getting the right reading.
    I have got a reading of 014ppm out of the pure outlet im running at 50psi with a 60/40 waste to pure I think.
    it takes me about 1 minute to fill a litre jug but I started running the ro this evening and its pretty cold not to sure if that makes a different to production so I am wondering if I can get that reading down closer to 000ppm
    any thoughts would be great.

    try turning the waste ratio up a bit to see if the ppm lowers.

    It will take some time for the membrane to settle. Manufacturers guideline is flush for 24 hours which is a lot of water to waste so I normally recommend that flush for 2 hours then run your r/o and over time the ppm will drop.

    At 50 psi I would have expected a flow rate of around 1.2l a min so your water flow from the tap may be a bit poor. Normally you can get 12/15 litres in a minute from your tap. Try measuring that and see what you get.

    For a new ro the ppm out of 12 seems rather high to me doug atkinson don't you think?

    The Pressure dictates the ppm Smurf, sounds about right but will come down a little more after it has embedded. If pressure was at 80 psi and flow rate was perfect then would come down more
