    Just after some advice.

    I bought a couple of cheap 11l DI vessels off of eBay a while ago. Now I'm wondering if they were cheap for a reason cos my resin doesn't seem to last very long compared to Gardiner's calculator.

    Does the quality of the riser and head make a difference in this regard or is it a case of if it works it's fine?

    Thanks for your help.

    What is your tap TDS? If it's high, your resin won't last as long as a low TDS reading. Give us a bit more info if you can.

    Also, do you have the flow of the water going in the correct direction? There should be a sign on the threaded part saying 'inlet' and 'outlet'.

    Hi Tuffers, thanks for the advice.

    My tds was about 80 but has recently shot up to 150 so I know I'll be using resin much faster than before but I still don't get anywhere close to Gardiner's resin calculator.

    I have definitely got the inlet and outlet the right way around. The tap water enters at the top of the vessel through a small mesh filter, makes its way through the resin to the bottom of the vessel and up the riser through a conical plastic filter.

    Any other ideas? Cheers

    You say you bought 2 vessels. Are you using them together, ie tap > vessel > vessel. How much water are you making? How long is the resin lasting, if you're using just 1 vessel? How fast is the water going through the vessel? I tend to trickle the water through, it takes maybe 2 hours to get say 400L of pure.

    I wouldn't pay much attention to the resin "calculator". Different resins brands & types perform differently with different water content anyway. The fact your input tds has risen near on 100% is the probable cause if nothing else has changed i.e. you're using the same brand resin that you normally do.
    Tuffers is correct in the fact that the slower the flow through a resin vessel- the better the resin will perform. This is the reason that I have my two vessels on the van- I fill my tank with tap water & pump though the vessels as I use water (on demand filtration).
    I have been DI only for over ten years & have tried virtually every combination of everything DI/resin wise- trust me, a Yorkshire man living in Scotland- they don't come much tighter than that!!:D I find Tulsion MB115 the best resin & have been using it for some years now. I recently tried various others again & none of them matched Tulsion for me.

    Also, give your vessels a swirl before running water through them if poss, probably not easy if you have them in your van, but if like me, they're in the garage, I will swirl them to get rid of any channels the tap water may have created in the resin.

    I use two 11Ltr vessels in my van. I fill the tank with tap water (tds 60ish) and pump it through the vessels on demand.
    I change one pot every 7 weeks (I allow it to read 002 before change) and use 400 ltrs a day on average.

    Hope this helps a bit.

    Yep, my input TDS is 90ppm, using the same amount of water I get approx 5 weeks per fill of 11ltr vessel.
