A method of monitoring the integrity of a flexible milk tube is disclosed. The flexible milk tube 10 comprises a main duct 12 and a plurality of secondary ducts 14 for discharging milk from the teat cup and for applying vacuum in the teat cup. The method comprises the following steps: a) Applying a pressure on at least a first group of the plurality of secondary ducts, in which pressure deviates from an ambient pressure. b) Determining the pressure in the first group of the plurality of secondary ducts. c) Determining a control pressure value with a predetermined desired pressure value, or a development in time of the control pressure with a predetermined desired development in time of a pressure valve. d) Supplying an alarm signal if the control pressure, or the development in time of the control pressure value, deviates to a predetermined extent from the predetermined desired pressure value , or the predetermined desired development in time of the pressure value.
