Have your will updated...I'm sure your gonna die of some type of water problem or that is how some people play it out to be.
We sanitize tank at least 2 a year.
But we do go places that has water that does not taste good, so we buy bottled water by the gallon in those places. I can usually tell with the first pot of coffee if water tastes bad or not.
I think you'll take more of a chance getting sick by eating in some tourist trap places.
We also have noticed that some places have some type of water that has a scale to it. Every spring we clean out hot water tank with a cheap Camping World nozzle things to rinse it out good also. Have also changed faucet aerators just to be safe with water pressure.
