Do you know why?
If you keep water in a copper vessel, preferably overnight or at least four hours, the water acquires a certain quality from the copper which is very good for your liver in particular and your health and energy in general. If water is being violently pumped and is traveling to your house through many turns in lead or plastic pipes, with all these bends and turns, much negativity happens to the water. But while water has a memory, it also has a way of unfolding itself back into its original state.
