Abstract

1. Drinking water flow installation comprising in a series connection a pipe separation unit (10) and a back flow preventer valve (32, 100) and further comprising a control valve (38), which compares the pressure at the inlet and the outlet of the installation with each other in order to connect a piston (36) actuating the pipe separation unit (10) to the inlet pressure or the atmosphere, respectively as a function of the pressure condition, characterized in that a pressure balancing valve (68, 138) is intergrated with the back flow preventer valve (32, 100).
