.From the XHose PDF Instructions:
This makes me wonder if you stored the hose in a tightly lidded box, would it still be unsafe to drink from?
Further searching led me to this really funny 3-page discussion on iRV2:
http://www.irv2.com/forums/f64/xhose-132507.htmlBottom line, for me, is a "no", even though I don't drink water from my tank.
Reviews lead me to believe this isn't a hose to be left connected under pressure for any length of time.
The End.
