Liquid supply system

Abstract

The invention related to liquid supply systems of buildings and constructions, where intake water line is connected to outer municipal, city, or local water supply. Also, liquid supply systems with two liquid sources, where intake liquid line is connected to outer water supply and simultaneously to the alternative water source, for example vessel filled with rainwater are known from the state of the art. Such systems can be used for cold as well as for hot water. The water supply system includes a liquid intake line, connected with at least two sources of water—an outer water supply line and an alternative source, made as a collecting vessel, and a liquid supply line, characterized in predominant water supply from the alternative source as the tank on the alternative source water supply line has the pressure higher than the pressure of the outer source.
