A friend once told me that the water from a cold tap is better to consume instead of from a hot tap (after it has cooled down of course) for the reason that the pipes are made of copper and the heating of the water has some sort of effect on thisIs there any evidence to support this or is this just a common myth?
Urban Myth once related to the the belief that the pipes were glued together using lead solder and the hot water would make some of the lead dissolve in the water. Debunked years ago. Lead solder is used for industrial and Commercial applications like making jewelry, etc. The solder used in food ( water falls in this category) does not use lead. There is no lead to enter the water or harm you.
The heating tends to separate the minerals out of the water thus much of the sediments in water heaters . Other than a very minute lead potential there shouldn't be a problem as the water going into the heater is the same as what is coming out just heated. The inside of a water heater is lined with a glazing or ceramic (like a bathtub) Any bugs molds ,fungi or viruses that come out of the heater had to come in from somewhere , that is the water coming into it . beside you are supposed to heat the water to kill these . All metal pipes create or more properly generates a coating on the inside that seals the direct contact with water (the greenish coating in copper pipes) when there is a damage or turbulence is in a section of pipe it strips away this coating and wears away the copper . Your body needs trace amounts of copper as with Zinc in galvanized pipe .
