thanks R12R and chris...
I need to take an actual pic of mine, as im not sure bout the red/green thing.
I also read on here that there is a certain way your supposed to turn on the tanks, like both closed, hook up pigtails, then lever or whatever to the tank you want, crack that open slowly, then crack the other one slowly so as to not flow too fast or something?
and to the people who prefer to manualy switch, hey, can I take you with me next time, cuz ive already done it 2x at 3am, and frankly, that was 2x too many!!!!
thanks
