- Abstract
- One of the performance requirements of great importance in relation to plumbing is hydraulic adequacy or hydraulic performance, which is related primarily to the general attribute of health and safety. The scope of the presentation is limited to certain aspects of the hydraulic performance of sanitary drain-waste-vent (DWV) systems. Considerable savings in material and labor costs have been reported to be possible through the use of a single-stack drainage system in place of a conventional system. The development of the experimental work reported herein came about as the result of a request to make technical recommendations concerning the suitability of such a system in a particular installation. Described is a test program developed looking toward the evaluation of the system against the essential criteria.
