PROBLEM TO BE SOLVED: To minimize the occurrence of such an unfavorable situation that renders a toilet provided with a drainage force-feeding apparatus suddenly unusable. SOLUTION: The number of times of turning-on operation of a motor 21 in a force-feeding part 20 and the number of times of turning-on operation of a motor 31 in a size reducing part 30 are counted in an operating number counting part 44 and an operating number counting part 45, respectively. The counts are displayed on a display part 481 and further are compared with threshold values predetermined according to the durable times, and the like, of the motors in a comparing part 46. When the results of the comparison show that the service life of the one the motor almost ends, a sound generating part 482 gives an alarm. Therefore, a motor or other movable part can be replaced or repaired before a toilet is made unusable due to trouble of a drainage force- feeding apparatus.
