How bigs that bad boy ? Atm imjust using a 11L by the garden tap and have the same in the van plumbed in - reckon I should be using a larger one really like you have in the van for efficiency and and swap out the 11L van vessel for the larger one - out of interest what happens when your TDS starts rising ? Which do vessel do you replace first and what order ?View attachment 24243View attachment 24244
Here’s what I have mate. Outside the van I have two DI vessels that contain older resin. View them as ‘softening’ the water, plus it’s a good way of getting more out of spent resin.
Inside the van I have a large DI vessel with fresh resin. This takes the water to zero. I fill the tank with it. I went the pre-tank route as we use a backpack for the backs & it’s easier to fill it up this way.
When I’m at home the water will go through the external DI vessels before reaching the van and going through the large one. When I’m topping up at a customer it’s just the large one that does the job.
Hope this helps!
