<p>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 diamter of the conduit so that the tubing can pass through the conduit and into the drain pipe.</p> |
