I have two fresh water hoses. They are manufactured for use in transporting drinking water and are usually white with a blue strip or mostly blue. They can be used without imparting plastic compounds into water.
I have a separate wash down hose, just a common green garden hose used only for rinsing the stinky slinky and other TT clean up chores. As I mentioned when I fill my fresh water tank I use my home garden hose.
Us old hose drinkers know you let the well water run until it is cold and has flush all the crappy tasting plastic chemical out; then you can enjoy the unique flavor of very hard, rusty, deep well water; delivered through your home pump, pipes, tank and outside spigot. None of which has been chlorinated in recent memory.
That is the same water you cook and make coffee with every day. To shower it need to run through the water softner. That is life in rural Indiana.
Safe travels.
