Abstract
This study is to evaluate the horizontal drain pipe system equipped with exclusive header piping for SI housing and propose the design method. In this paper, both single fixture drain and plural fixture drain were carried out by using a model piping (with a length of 7〜11m) to compare the performance of this system with conventional drain system, and the features of this system was obtained. The authors describe the knowledges obtained from the perfomance evaluation experiment, using the characteristic of fixture discharge, the pressure in pipe/trap seal water lost, and the flow velocity in pipe/carrying performance as an evaluation index.
