Nooooooooooooooooooooooo!!!!!!!!!!! In many parts of the world the hot tap piping is still lead, not just in weird and wonderful places, but many homes in the UK still have lead piping for their hot water systems. Plus hot water tanks are very rarely cleaned. In some places, the water for the hot water may be stored (in the roof / attic areas) and those water tanks are not always sealed - dead mice and rats and even bigger creatures get into those tanks. You don't want to be using the hot tap in an unknown location for anything that goes in your mouth!
