    Hi Colin. Should definitely be zero. If you have just filled the resin vessel, did you pack it well in. If it is not packed enough then the water can find its own way out without clearing the tds. Also an easy mistake, but is worth checking that you have connected the in and out of the resin vessel the right way round.

    In an absolute emergency you will probably get away with 8, but would recommend trying to pack a bit more resin in.

    Another thought - make sure that the water has been flowing for a minute before taking a tds reading, and make sure that the container you use to hold the water for testing has been well rinsed out the test Water .

    hope fully this will help trace the problem

    Just had another thought - are you putting the water into the tank, and then filtering on the way from the tank to the pole, or are you filtering on the way to the tank. If filtering on the way to the tank, there may be some impurities in the tank that the water is picking up after filtering ( particularly with a new tank).
    It is usual to filter on the way from the tank to the pole to prevent this, and also to keep the chlorine etc in the water until needed as it helps keep the water safe from bacteria etc.

  3. Yeah, you must have the DI vessel as the last purifyer before the pole as tanks can hold all sorts of smellies!!!!
    If packed in well with water as soft as yours your resin should last for ages.
    If only I could have 26 - mine is 486!!

    You say you have recently installed a DI in your van.Your resin should last between 4-6 months with ppm at around 26.First check connected the right way round and after the pump just before the pole hose,Make sure the resin is filled to just under the neck of the vessel and packed down (give a couple of taps on the ground to settle the resin)

  9. 26ppm!!!!!!!!!!!!!!!!![size=x-large]

    M
    After my water has travelled through 2 3 pre-filters and a 40/40 [/size]membrane I get down to 34ppm!!!!!
    I then resin the rest down to zero.
    Some resin is better than other though.
