From the milking station (4) a connection pipe (12) leads to the transport conduit (6) at a connection point (14). The arrangement (2) for milking animals comprises a valve arrangement (18). The cleaning liquid arrangement (16) is connected to the transport conduit (6) via the valve arrangement (18). The valve arrangement (18) is adapted to be positioned in at least a first position and a second position. In the first position the transport conduit (6) forms a loop such that two flow paths from the connection point (14) to the connection conduit (10) are provided by the transport conduit (6), and in the second position the loop is interrupted such that one flow path only from the connection point (14) to the connection conduit (10) is provided by the transport conduit (6).
