PROBLEM TO BE SOLVED: To provide a device to run the sanitary sewage outside by preventing the sanitary sewage from running into a house inlet in repairing the house inlet, and a repairing method of the house inlet using this device. SOLUTION: Sewage is collected in an automatic collector A of the structure in which a plurality of branch pipes 6 are connected to a main pipe 5 through a drum-like appliance mounted in a plurality of pipes 2 to discharge the sewage into a house inlet 1, a valve 7 is provided on each branch pipe, a water level sensor 4 is provided on a conduit 8 to connect the automatic collector A to each drum-like appliance, and the water level sensor 4, the valve 7 and a pump C are electrically connected to a control device B. When the sewage level reaches a specified level, the control device B operates the pump C with the corresponding valve 7 in an open condition by the electric signal from the water level sensor 4. When the sewage pumping is completed, the corresponding valve 7 is closed, and the pump C is stopped when all valves 7 are closed. An ultrasonic sensor capable of detecting water by the ultrasonic wave is preferable for the water level sensor 4.
