Colour of water hose

So you fill the water tank, which is what, 30 or 40 gallons? And how much of that water do you actually drink? And do you really think the moment that the water spent in the hose is more important than the environment of the tank that it sits in for days at a time?

Yeah... for my money I'll just buy gallons of water for drinking and save the tanked water for washing.
