Fresh water tank - do you drink water from it?

After installing the marine port on my tank and getting in there to clean it.......
I now drink/cook with reverse osmosis filtered water.
It works better with beer too . :)

My doctor warned me not to drink the water from my rv water tank because the one of the universities did a study finding that a large percentage of the people tested ended up having uncontrollable urges to become moderators .
I said "OMG no " :S :B
