    so my water ppm is very low in my current area its at 045 and will only need a DI vessel. is it better to have 2 smaller di vessels or better just to use a single 11 litre vessel ?, im just not sure which is better

    Not a lot tbh around 300 a week as still do a fair bit of tradding to break up the day a bit, theres a resin calculator on wcw and on Gardiner's website

    Definitely worth using double DI as you'll save on resin. When my single DI vessel reaches 5ppm I attach a second vessel after it with new resin in - the resin in this 2nd vessel has less work to do to get the water down to 0ppm. I'll remove the 1st vessel once it reaches tap TDS (which is 77ppm where I am - used to be 54ppm).

    My reading is currently 049. I use two 11 ltr DI's. I change the resin in one DI every 6 - 8 weeks. I have a 400 lrs tank used daily.

    Where are you based slipknot ?
