Long story , erm , to start with when the tds was on the rise in the di on the van i took it out and put it in a little bin with an inlet and outlet on it , put my garden hose to it and let it trickle through slowly , about 20 L an hour , the tds was back to 000 due to the slow flow rate , i know that 20 L an hour is naff but if its on all day and night your looking at 300 L a day .
I have now started putting new resin straight into the bin and running it all the time , i put 4.5 KG of resin in at a time {one quater of a 25 L bag} , this last for about 3000 to 4000 L at a time , with my tap TDS of 100 , if i was to use the same ammount of resin in the van DI i would only get 1500 L tops , so as you can see , i am doubling the life of my resin .
And as all the water that now goes into the van is at 000TDS , the di on the van will last for ages , i used to have to change every week , but now it hasnt been changed for i reckon about 3 months and its still going .
