Why not use a garden hose???
Well, the last hose I bought had a warning on it not to drink
from it. It said the hose leaches toxic agents into
the water.
Normally I discount these kinds of warnings as some company
trying to avoid a lawsuit but Google seems to confirm.
Perhaps real underground water pipe is the best answer.


The original post had the hose being drained after each use,
to prevent freezing ; and it was being used for livestock.
If anyone is seriously worried about the toxins for this scenario -
- be my guest - it must be a nice life, when you have nothing
more-serious than that to worry about !
