The present invention wants to indicate a domestic-water supply and withdrawal system for improving the possibility of taking samples. To this end it is suggested that a sampling valve (2) is arranged between the cold-water and/or hot-water angle valve (16, 18) and the washstand fitting (10). ## Claims ### Claim 1 A domestic-water supply and withdrawal system for a washstand with wall-mountable angle valves (16, 18) for cold and hot water and a washstand fitting (10) which is coupled in flow communication with the associated angle valves (16, 18) via pipe or tubing sections (12, 14), characterized by a sampling valve (2) arranged between the cold-water and/or hot-water angle valve (16, 18) and the washstand fitting (10). ### Claim 2 (depends on 1) The domestic-water supply and withdrawal system according to claim 1, characterized in that a backflow preventer (6) is arranged between the sampling valve (2) and the washstand fitting (10). ### Claim 3 (depends on 2) The domestic-water supply and withdrawal system according to claim 2, characterized in that the backflow preventer (6) is arranged in a housing (4) of the sampling valve (2). ### Claim 4 (depends on 2) The domestic-water supply and withdrawal system according to claim 2, characterized in that the backflow preventer (6) is secured via a retaining ring (42) to the housing (4) of the sampling valve (2). ### Claim 5 (depends on 2) The domestic-water supply and withdrawal system according to claim 2, characterized in that the backflow preventer (6) is captively received in the housing (4) of the sampling valve (2). ### Claim 6 A domestic-water supply and withdrawal system for a washstand with wall-mountable angle valves (16, 18) for cold and hot water and a washstand fitting (10) which is coupled in flow communication with the associated angle valves (16, 18) via pipe or tubing sections (12, 14), characterized in that a sampling valve (2) is arranged between the cold-water and/or hot-water angle valve (16, 18) and the washstand fitting (10) and that a backflow preventer (6) is arranged between the sampling valve (2) and the washstand fitting (10). ### Claim 7 (depends on 6) The domestic-water supply and withdrawal system according to claim 6, characterized in that the backflow preventer (6) is secured via a retaining ring (42) to the housing (4) of the sampling valve (2). ### Claim 8 (depends on 6) The domestic-water supply and withdrawal system according to claim 6, characterized in that the backflow preventer (6) is captively received in the housing (4) of the sampling valve (2). ### Claim 9 A sampling valve (2) for a domestic-water supply and withdrawal system comprising a housing (2) having an inlet (20), outlet (22) and sampling opening (24), wherein the inlet opening (20) and the outlet opening (22) are in communication with each other via a flow passage formed in the housing (4), and wherein the housing (4) encloses a valve body movably arranged therein, which in its closing position shuts off the sampling opening (24) from the flow passage and which in an open position opens the flow passage to the sampling opening (24), characterized in that a backflow preventer (6) is assigned to the outlet opening (22). ### Claim 10 (depends on 9) The sampling valve (2) for a domestic-water supply and withdrawal system according to claim 9, characterized in that the backflow preventer (6) is arranged in a housing (4) of the sampling valve (2). ### Claim 11 (depends on 9) The sampling valve (2) for a domestic-water supply and withdrawal system according to claim 9, characterized in that the backflow preventer (6) is secured via a retaining ring (42) to the housing (4) of the sampling valve (2). ### Claim 12 (depends on 9) The sampling valve (2) for a domestic-water supply and withdrawal system according to claim 9, characterized in that the backflow preventer (6) is captively received in the housing (4) of the sampling valve (2). ### Claim 13 (depends on 3) The domestic-water supply and withdrawal system according to claim 3, characterized in that the backflow preventer (6) is secured via a retaining ring (42) to the housing (4) of the sampling valve (2). ### Claim 14 (depends on 3) The domestic-water supply and withdrawal system according to claim 3, characterized in that the backflow preventer (6) is captively received in the housing (4) of the sampling valve (2). ### Claim 15 (depends on 7) The domestic-water supply and withdrawal system according to claim 7, characterized in that the backflow preventer (6) is captively received in the housing (4) of the sampling valve (2). ### Claim 16 (depends on 10) The sampling valve (2) for a domestic-water supply and withdrawal system according to claim 10, characterized in that the backflow preventer (6) is secured via a retaining ring (42) to the housing (4) of the sampling valve (2). ### Claim 17 (depends on 10) The sampling valve (2) for a domestic-water supply and withdrawal system according to claim 10, characterized in that the backflow preventer (6) is captively received in the housing (4) of the sampling valve (2).
