Abstract

A dirt trap for flush basins such as urinals include a perforated base plate and a central projection which receives a basket. The basket includes upwardly extending arms joined together at a location spaced upwardly from the base plate by a connecting ring, the distal ends of the arms being bent inwardly and downwardly toward the central axis of the basket. A weight is provided in the base plate to maintain the position of the dirt trap during flushing.
