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.

1 . A water supply system comprising a liquid intake line, connected with at least two sources of water being an outer water supply line and an alternative source, formed 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. 
     
     
         2 . The water supply system according to  claim 1 , additionally comprising a pressure reducer placed in a spot of the outer water supply line to liquid intake line connection, 
     
     
         3 . The water supply system according to  claim 1 , additionally comprising a liquid purification unit. 
     
     
         4 . The water supply system according to  claim 1 , additionally comprising an alternative source flashing line from the outer water supply line.
