Yep the tank is just tap water and I run a twin di setup (2 big blue things in the back of van) to get the water down to 000, up side of this system is I can fill up in 20 mins and be out working again.
This setup up will only work if you have a low Tds reading, my tap water is 090 at the most.

Thanks Stuart,
So the better the system the quicker it can purify water. What does 'Tds reading' and what do you do if you don't have a low Tds reading + how do you work out what your Tds level is?
