Tap water safe, but not the warm water

In the United States., tap water is nominally safe to drinking straight from the faucet. Although some people may not like to drink tap water because of its slightly strange flavor, it is indeed safe for drinking. However, one has to remember that hot tap water from the faucet may not always be safe for drinking, because it comes from a different water source and the quality of hot water is often far lower than that of cold water.
