Abstract

A bushing (58) has an entry portion (68) which is secured to a urinal housing (50) and an exit portion (70) which faces a drain pipe (54, 54a, 54b). The entry portion interior surface (74) is fittable about and sealingly grips the urinal exit tube (52). The interiors of the entry and exit portions lie on a common axis (58x) and with the axis (52x) of the urinal exit tube. These axes define a sloped incline and, thus, a built-in, gravitationally-directed downwardly-disposed inclination. Because the axes usually do not fall on the axis (56x) of the conduit, they are angled and offset from the conduit axis. The offset of the bushing raises it above the axis of the conduit. Tubing (60, 60a) is secured at its end (62, 62a) to the bushing exit portion so that the tubing axis at its end (62, 62a) similarly is raised above the conduit axis. The tubing extends from the bushing at an incline that is determined by the built-in incline of the bushing. This tubing is smaller in its outer diameter than the inner diameter of the conduit so that the tubing can pass through the conduit and into the drain pipe. The interior surface (74) of the bushing is offset from its outer surface which is secured to the conduit. Thus, the tubing is allowed to ensure that the conduit will not so contact the tubing as to deleteriously affect the downward inclination of the tubing. An orientation indicator tab (92) on the bushing ensures that its inclined orientation is properly positioned vis-a-vis the conduit. The exterior surfaces of the bushing are designed to enable it to fit within a variety of conduits, to accommodate new and existing connections such as flanges and hardware associated with the drain pipe, to ensure its durability, and to otherwise enable retrofitting to new and existing installations.
