ABSTRACT:
A foreign matter trap for use in a drain such as a shower or sink drain in which water flows downwardly through a drain pipe, the trap having an element for removably positioning in the drain pipe including a downwardly extending longitudinal member, a plurality of layers of foreign matter catching members extending generally radially from the longitudinal member, each layer being formed of a plurality of spaced apart spicule members, the spicule members of each layer covering less than a complete cross-sectional circumferential area leaving a portion free for the flow of water therepast, the layers being arranged so that the spicule members in adjacent upper layers extend over and above the free cross-sectional areas of the next lower layer so that water may continue to flow through the drain even when the spicule members of any layer are completely closed by trapped foreign matter.
