Water Distribution

In this house, there are two tanks of water, cold water tank and hot water tank. There are also four places that have to be distributed by those tanks of water, bathtub, wash basin, toilet, and sink. First, cold water tank as the main water tank, distributes the cold water into those four places (bathtub, wash basin, toilet, and sink) and also into the hot water tank. In hot water tank, the cold water from cold water tank is changed to be hot water, and then it distributes hot water to three places, bath, wash basin, and sink. So, cold water tank distributes the cold water directly to bathtub, wash basin, toilet, and sink. And the hot water tank gets the water from cold water tank and changes the water to be hot water before distributes to bathtub, wash basin, and sink.
