Abstract: A test fitting for installation in a plumbing system comprises an annular sleeve having opposed first and second open ends and an inner surface that defines an open interior space and a hole. A cord has a first portion removably positioned in the sleeve's interior space and a second portion extending through the hole for removing the cord from the interior space through the hole. The first portion of the cord forms a watertight spiral disc that extends across the interior space to define a first area completely separated from a second area, and an outer edge of the spiral disc may be supported by a ledge extending from the inner surface into the interior space. Means are included for selectively sealing the hole after the cord is withdrawn through the hole, such as a plug complementary to the hole.

Abstract translation: 用于安装在管道系统中的测试配件包括具有相对的第一和第二开放端的环形套筒和限定开放的内部空间和孔的内表面。 绳索具有可移除地定位在套筒内部空间中的第一部分和延伸穿过孔的第二部分，用于通过孔从内部空间移除绳索。 帘线的第一部分形成水密的螺旋盘，其横过内部空间延伸以限定与第二区域完全分离的第一区域，并且螺旋盘的外边缘可以由从内表面延伸到 内部空间。 包括用于在帘线通过孔（例如与孔互补的插头）取出后选择性地密封孔的装置。
