THE SURVEY FOR THE TROUBLE CASES OF HOUSEHOLD DISPOSERS INSTALLED IN ESTABLISHED STAND-ALONE HOUSES, PIPING PLAN AND FLUIDITY EXAMINATION

Although the direct discharge disposer which discharges drainage to a sewer directly had been progressing quickly, the demand quality to the established stand-alone house installation disposer was not clear. Therefore, the trouble case of the disposers in the direct discharge installation was investigated by the questionnaire. The kitchen piping construction conditions of the established house were also investigated and piping was modeled. In 4 L/min which is the general water supply velocity of a manual water supply disposer operation, it became clear that the danger of the pipe clogging by egg shell deposition was high.
