Ok. I had a feeling I'd have trouble. Filled up with resin 5kg. Connected hoses up using good connectors so floor wouldn't flood(thanks paul). Come all ou nicely & 1st go was 0.20. Thought not to bad. Stuck at it for half hour running it through & lowest I could get was 124ppm. Did get it to 040 once but that was rare. Have give it a good shake but it's mostly reading between 140 & 150ppm. Am I doing somet wrong or do I need somet else. My water is 276ppm. Please help chaps. The di has now been "chucked" in the shed still with water in it in disappointment & an irate partner moaning coz messed up the kitchen lol.
