ABSTRACT:
The present invention provides an overflow drain assembly for a sanitary vessel, wherein the vessel includes a bottom surface and at least one side surface depending therefrom, such that the surfaces together define a reservoir for receipt and storage of fluid thereby and at least one ledge is provided along at least a portion of at least one vessel side surface. The overflow drain assembly comprises a fastening plate having an envelope with a top surface and a bottom surface defining a generally planar body that lies proximate the vessel ledge, and a tarp portion depending curvilinearly therefrom. The tarp portion has a generally planar bottom surface disposed adjacent at least a portion of at least one vessel side surface so as to define a fluid egress therebetween for delivery of fluid from the vessel reservoir to a waste conduit in fluid communication therewith. A port adapter establishes the fluid communication between the vessel reservoir and the waste conduit, and a retaining means is provided for retaining the fastening plate to the vessel. At least one platform member may depend downwardly from the envelope bottom surface for elevation thereof relative to the vessel ledge. The envelope top surface may include at least one index defined thereon to indicate a location of the waste conduit relative to the fastening plate. The present invention also provides a system for preventing fluid overflow from a sanitary vessel.
