ABSTRACT:
A combined floor sink and strainer for removing solid particles contained in the fluid passing through it. The combined floor sink and strainer has a hollow substantially rectangular housing, a strainer basket for holding the solid particles or sediment removed from the fluid passing through the combined floor sink and strainer and a locating and support structure for locating and supporting the strainer basket within the housing. The support structure and strainer basket have perforations to permit the passage of liquid but prevent the passage of solid particles over a particular particle size. The housing has a removable lid with three inlets and an outlet in its lower portion and a locating and support flange surrounds the upper portion of the housing the permit the housing to be removably located in the floor. The construction of the strainer basket and the strainer basket locating and support structure is such that three different paths are provided depending upon the amount of the debris collected in the strainer basket and this prevents a reduction in fluid flow as the sediment builds up in the sediment basket.
