An irrigation system, e.g. for use in rectal irrigation, is disclosed. The system comprises a reservoir for an irrigating liquid and a probe for arrangement in a user, wherein said probe comprises an inflatable balloon for fixing the catheter in a body cavity. A first pump is provided for directly or indirectly pumping irrigation liquid from the reservoir to the probe, and a second pump is provided for pumping a fluid to the balloon for inflation. A control unit is arranged for controlling the transfer of the irrigation liquid and the fluid, wherein the control unit further comprises a valve for releasing fluid from the balloon for deflation, the valve being provided with a manually operable balloon control element. Tubing provides fluid communication between the reservoir, control unit and probe. The control unit and the first and second pumps are further arranged as an integrated unitary component, and the manually operable balloon control element is arranged in the vicinity of the second pump.
