ABSTRACT:
An all plastic floor drain including a rigid plastic connector body and a rigid plastic strainer plate that is received in an annular recess in the connector body. The strainer plate includes a plurality of positioning pins that extend from the lower surface thereof and the annular recess in the connector body includes a corresponding number of positioning apertures to receive the positioning pins. Preferaby, there is free movement between the positioning pins and the positioning apertures when the pins are first inserted in the apertures, but one of the other of the pins or the apertures is tapered so that there is an interference fit as the strainer plate approaches its final position relative to the connector body, to securely connect the strainer plate and the connector body and to provide a substantially flat upper surface level with the surface of the floor. The use of all plastic parts and the absence of metallic connectors avoids corrosion.
