thanks for your feedback :)
to get drinking water this way is a great idea in general but here in germany and for me it wouldnt make too sense because the water out of any regular faucet is drinking water. thats also why i cant tell you much atm about the food-grade plastic because i havent digged into that topic too much. i was just looking for a water tank in general.
Thanks for the reply. Same issues here in the UK too about the tap water being perfect but it was just a thought about a further step towards off-grid life!
Have a great weekend and keep up the great posts :-)
thanks, i will def continue making updates or reports on my projects ;)
