The flushing stations have measuring devices for the temperature change in the branch pipe or the throughflow through the branch pipe, and/or measuring devices for the temperature change or the throughflow. The system includes and the method uses a control unit which is connected to the measuring devices by means of data cables or by radio. The control unit has an evaluation module for the data transmitted by the measuring devices, and the evaluation module is set up to determine, on the basis of the transmitted data, which flushing stations need to be flushed simultaneously in order for the riser or distribution pipe to be flushed. ## Claims ### Claim 1 A system for flushing a drinking water installation, comprising at least one riser or distribution pipe, a plurality of branch pipes connected to the riser or distribution pipe, consumer devices and flushing stations connected to the branch pipes, wherein the flushing stations have measuring devices for the temperature change in the branch pipe or the throughflow through the branch pipe, and/or measuring devices for the temperature change or the throughflow are provided, a control unit which is connected to the measuring devices by means of data cables or by radio, wherein the control unit has an evaluation module for the data transmitted by the measuring devices, and the evaluation module is set up to determine, on the basis of the transmitted data, which flushing stations need to be flushed simultaneously in order for the riser or distribution pipe to be flushed. ### Claim 2 (depends on 1) The system according to claim 1, wherein a plurality of risers or distribution pipes for the feed flow and return flow of a hot water pipe and a cold water pipe are provided and the risers or distribution pipes have a larger diameter than the branch pipes. ### Claim 3 (depends on 1) The system according to claim 1, wherein each flushing station is assigned an ID and, on the basis of the ID, the flushing station is locally assignable in the system. ### Claim 4 (depends on 1) The system according to claim 1, wherein the evaluation module is set up to output a notification as to which riser or distribution pipe needs to be flushed. ### Claim 5 (depends on 1) The system according to claim 1, wherein the control unit comprises a configuration module which proposes which flushing station is to be flushed depending on the riser or distribution pipe to be flushed and via which at least one of the following parameters: flushing time, flushing duration, flushing for the hot water pipe and/or cold water pipe and flushing once or in a periodically recurring manner is settable. ### Claim 6 (depends on 1) The system according to claim 1, wherein the evaluation module is set up to initiate flushing of the riser or distribution pipe automatically by simultaneous flushing of the flushing stations. ### Claim 7 (depends on 1) The system according to claim 1, wherein the consumer devices are connected in the branch pipes via a serial and/or loop pipe system and the connection of the consumer devices is realized via loop fittings. ### Claim 8 A method for flushing a drinking water installation, comprising at least one riser or distribution pipe, a plurality of branch pipes connected to the riser or distribution pipe, consumer devices and flushing stations connected to the branch pipes, wherein the flushing stations have measuring devices for the temperature change in the branch pipe or the throughflow through the branch pipes, and/or measuring devices for the temperature change or the throughflow are provided, a control unit, wherein the control unit is connected to the measuring devices by means of data cables or by radio and receives the data about the throughflow through the branch pipes and/or risers or distribution pipes, the control unit has an evaluation module for the data transmitted from the flushing station, and the evaluation module determines, on the basis of the transmitted data, which flushing stations need to be flushed simultaneously in order for the riser or distribution pipe to be flushed. ### Claim 9 (depends on 8) The method according to claim 8, wherein the evaluation module outputs a notification as to which riser or distribution pipe needs to be flushed. ### Claim 10 (depends on 8) The method according to claim 8, wherein the control unit comprises a configuration module which proposes which flushing stations are to be flushed depending on the riser or distribution pipe to be flushed and via which the flushing stations to be flushed can be selected manually. ### Claim 11 (depends on 10) The method according to claim 10, wherein, via the communication module, at least one of the following parameters: flushing time, flushing duration, flushing for the hot water pipe and/or cold water pipe and flushing once or in a periodically recurring manner is settable and flushing is initiated by a user of the control unit. ### Claim 12 (depends on 8) The method according to claim 8, wherein the evaluation module initiates flushing of the riser or distribution pipe automatically by simultaneous flushing of a plurality of flushing stations. ### Claim 13 (depends on 2) A system according to claim 2, wherein each flushing station is assigned an ID and, on the basis of the ID, the flushing station is locally assignable in the system. ### Claim 14 (depends on 9) A method according to claim 9, wherein the control unit comprises a configuration module which proposes which flushing stations are to be flushed depending on the riser or distribution pipe to be flushed and via which the flushing stations to be flushed can be selected manually.
