Floor sink strainer and assembly

A floor sink and strainer assembly comprising:

• a receptacle including a basin for collecting water, the basin including a plurality of sidewalls and being open at one end of the side walls and generally closed at an opposing end of the sidewalls by a bottom wall, the bottom wall defining a bottom wall perimeter at a juncture with the sidewalls, the bottom wall further defining an outlet opening therein;
• a strainer received in the basin, the strainer including a central body and a generally planar flange located about the central body, the central body defining a projection relative to the planar flange and having a plurality of apertures extending therethrough, the flange being supported by the bottom wall and having a flange perimeter extending to a position greater than halfway and less than completely between the outlet opening and bottom wall perimeter of the basin;
• and
• the sidewalls of the basin and the flange cooperating to constrain lateral movement and lifting of the strainer such that the central body remains located over the outlet opening during an influx of water into the floor sink and strainer assembly.
