Asked you for some advice a few days ago about starting up and thanks for the replies.
Now if I'm correct is this everything I would need to start-up wfp (cheaply):
Backpack
Pole and brush head
DI Vessel with resin
RO unit (live in hard water area)
Drums
TDS
From what I've read I would have to ensure the mains water goes through the RO, then through the DI, where it would go into 25ltr drums, which I would then transfer to the back pack, is this correct?
