Tests were performed in prototypes of building sanitary sewer systems, considering Brazilian building typologies, in which the pressures in different points of the systems were evaluated, as well as the behaviour of seal traps. The prototypes were tested with several sanitary appliance flow arrangements and different diameters, all of them having only primary ventilation. The aim of this study is to provide building drainage system designers with safer conditions for using that type of ventilation system, which was introduced in the latest revision of NBR 8160 – Building Sanitary Sewer Systems – Design and execution – Procedures. Este artigo apresentada algumas condições-limite de utilização do sistema de tubo de queda único em sistemas de esgoto sanitário residencial, através da avaliação das condições de ventilação dentro desses sistemas. Foram realizados ensaios em protótipos de sistemas prediais de esgoto sanitário residencial, usando tipologias de edificações brasileiras, em que foram analisadas as pressões em diversos pontos dos sistemas, como também o comportamento dos fechos hídricos dos desconectores. Os protótipos foram ensaiados com diversos arranjos de descarga e diâmetros de tubulações, todos dotados apenas da ventilação primária. O objetivo desta pesquisa é proporcionar aos projetistas de sistemas hidráulicos prediais condições mais seguras de utilização desse tipo de subsistema de ventilação, o qual foi introduzido na última revisão da NBR 8160 – Sistemas prediais de esgoto sanitário – Projeto e execução – Procedimento.
