Tap -> RO +DI Filtration -> Water tank -> Pump -> Pole -> Window

You don't add anything to the water,it has to be pure.

I thought you need to add some resin to the vessel?  ???

I've never used those DI vessels as my 450 GPD Amfor membranes RO produces less than 005 ppm water.So i use 700 ml 10 inch housing DI units.

But I think they fill those DI vessels around 3/4 or 2/3 ratio,I'm not sure.

What's your water quality after the RO,before the DI vessel?

I flashed the tank after I got the van as when I used the water to wash my house widows it still had water marks and now unsure as to how much resin is needed in the vessel? Thanks

You will be fine mate,there is lots of work out there.Try canvassing the small villages around first like Shoscombe,Wellow,Stoke St. Michael etc.

Old chap covering most of Coleford was due to retire some years ago,he might be considering selling up.
