Abstract
Abstract A lavatory spout having a one-piece integrally molded plastic body with a depending hollow shank portion and an outwardly extending hollow spout portion. The spout and shank portions are in open communication so that water passes through the shank and spout portions. A bottom cover flange is also formed on the body spout portion and extends outwardly along the length of the spout portion. Desirably, the lower flange forms a ring around the upper portion of the shank. A hollow elbow conduit is secured to the outer open end of the spout portion, providing elbow passage at the outer end thereof. A separate cover extends over the spout, the elbow conduit and the upper portion of the shank with the sidewalls of the cover meeting the sidewalls of the body cover flange. Means are provided for securing the cover to the body and to the elbow conduit. A pop-up rod tube, of brass or molded in one piece of a plastic material, is provided within the body and extends downwardly into the shank portion. Seals are provided between the upper and lower portions of the pop-up rod tube and the interior of the body to provide an annular water passage.
