Abstract
A drain assembly includes a cup connected to the sink and having an extension tube. A seal and an urging ring are mounted to the cup from the underside of the cup. A positioning plate is fixed to the cup and the extension tube extends through a central hole of the positioning plate. A plurality of bolts extend through the positioning plate and contact against the urging ring. A filtering seal device is connected to the cup. A connector is fixed to the extension tube and a positioning member is threadedly connected to the extension tube of the cup. The positioning member is engaged with the central hole of the positioning plate. By the engagement of the positioning member and the positioning plate, the assembler can quickly position the drain assembly.
