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:] [6.] A method for insulating a P-trap drain piping assembly located under a sink including multiple pipe sections joined at junctures, the method, comprising:placing a first J-shaped cover piece having an end over a pipe section;placing a second, generally straight cover piece having an end over another pipe section;positioning the first and second cover pieces such that the ends of the pieces are adjacent one another at the juncture;wrapping a collar structure having opposing ends around the juncture;the collar structure having ends which include cooperating structures, the cooperating structures being joinable for joining the ends together and separatable for readily separating the ends of the collar and;joining the cooperating structures at the ends to form a continuous collar structure such that the collar structure and cover pieces form a generally continuous insulative cover over the joined pipe sections of the P-trap assembly.
