Abstract: A floor waste (10) including a filter basket (16) having a magnet (18). The magnet (18) attracts a movable valve member (27) upwardly from a seat (22) to allow liquid to pass through the seat (22). When the basket (15) is removed the movable valve member (27) closes the seat (22). In one embodiment the valve member (27) includes a valve disk 29 that prevents the flow of liquid through the seat (22) when engaged therewith, while in another embodiment the disk (29) has a series of passages (31) that permits the flow of liquid through the seat when the disk (29) is engaged with the seat (22).
