Abstract
Abstract A drain trap apparatus is provided for preventing the passage of debris into a drain opening which includes a disposable filter and which allows complete drainage of the wastewater. The drain trap has an annular support member which is semi-permanently attached around the drain opening. A passageway extends radially through the support member so that water will be allowed to pass through the support member. A filter, preferably of a flexible plastic mesh material, is removably attached to the support member by a plurality of hook members, such as the hook portion of a hook and loop fastener.
