ABSTRACT:
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.
