A cover assembly and methods for covering undersink piping includes insulative cover pieces placed over respective pipe sections such that their ends are adjacent at pipe junctures. Collars are slidable over or inside the cover pieces to be moved to cover the junctures. An alternative cover structure may be wrapped around the pipe juncture to form a generally continuous insulative cover, or alternatively, the fastening structures are insulated such that when the pipe sections are assembled together, the cover pieces and insulating fastening structures form a continuous insulative cover. In an alternative embodiment, one of the cover pieces is dimensioned to slide upwardly and downwardly on a pipe section and a collar structure is placed over the exposed pipe section to provide a continuous cover piece. In another alternative embodiment, pipe sections such as a trap pipe or offset grid drain are insulated by a unique insulative method to produce a generally continuous insulative cover layer on the pipe section which is free of slits or openings to prevent contaminants and bacteria from accumulating on the pipe. A still further embodiment utilizes a cover piece for a trap pipe which includes a projection and closure structure for covering the drain opening of the trap pipe but allowing access to the drain opening without requiring removal of the cover piece or disassembly of the P-trap piping assembly.

[ What is claimed is:] [1.] An insulative cover piece for a trap pipe of a P-trap drain pipe assembly comprising two vertical sections extending generally parallel to one another and curved section connecting the vertical sections to form a continuous cover piece, at least one of said vertical sections having a terminal end for forming an overlap with an adjacent cover piece, the overlap when formed being in substantial contact with the drain pipe assembly when applied thereto for forming a substantially gap free fit, each section of the cover piece being free of slits and openings along a substantial portion of its length to provide a generally continuous cover piece to completely cover said trap pipe and reduce dirt and contaminants from being trapped on said cover piece and trap pipe.
