I *snick* *twitch* drink from my *twitch* *twitch* fresh tank all the time and *snort* *twitch* *snort* *twitch* *snick* have no issues *twitch* *twitch* *twitch*.
Seriously guys there are a lot worse things than what's in your tank. Have any of you ever been sick or heard of someone getting sick and it being directly attributed to the tank water in an RV?
Frankly, if you "don't want to take the chance" you shouldn't be camping.
