patience patience.....5 days is a very short time to have to wait and if im reading it right if your not getting it untill friday coming and your ro/di produces 50 gpd then you should have more then enough come friday anyways??
cool idea but would take alot of time as snow doesnt melt down to very much and edmonton isnt really known for its clean snow lol
cheers buddy im interested in if it works for you
