Abstract: A drinking and domestic water system with a transfer point (22) from the public water supply network, a line (2, 4) from which at least one ring main (10; 38, 40) branches off, wherein the ring main (10) branches off from the line (2, 4) via an outlet opening (14) and is led back into the line (2, 4) via an inlet opening (16), wherein a flow resistance element (36) is arranged in the line (2, 4) between the outlet opening (14) and the inlet opening (16), or wherein the ring main (38, 40) is led back into a circulation line (6) via the inlet opening (16). The present invention aims to provide such drinking and domestic water system, which is intended to simplify the shutting off of the ring main for functional tests, cleaning measures or maintenance purposes.

Abstract: The present invention relates to a drinking and domestic water system with a transfer point (22) from the public water supply network, a line (2, 4) from which at least one ring main (10; 38, 40) provided with at least one consumer (12) branches off, wherein the ring main (10) branches off from the line (2, 4) via an outlet opening (14) and is led back into the line (2, 4) via an inlet opening (16), wherein the line (2, 4) and the ring main (10) are led in parallel and a flow resistance element (36) is arranged in the line (2, 4) between the outlet opening (14) and the inlet opening (16), or wherein the ring main (38, 40) is led back into a circulation line (6) via the inlet opening (16). The present invention aims to provide such drinking and domestic water system, which is intended to simplify the shutting off of the ring main for functional tests, cleaning measures or maintenance purposes.
