A BASIC STUDY ON A DRAINAGE SYSTEM DEDICATED FOR SUPER WATER-SAVING TYPE TOILETS USING LESS THAN ONE LITER OF FLUSH WATER

Abstract

The study aims to examine a super water-saving type toilet that uses less than one liter of flush water; significantly less than the upper limit amount of flush water specified by JIS (Japanese Industrial Standards), and develop and evaluate the performance of a drainage system dedicated for installing the toilet. A basic experiment is reported in the report, in which said super water-saving type toilet was used, on the assumption that the toilet was installed to a combined flow-type stack system, and the manner in which the drainage performance was affected and the securing of good carrying performance of the house drain were examined.
