The third section couples second ends of each of the first and second sections together and comprises a structurally weakened area therein which is manually separateable for forming first and second cover pieces from said unitary body. The ends of the separated first and second sections further include structurally weakened areas for trimming the lengths of the sections during installation whereby the piping assembly is quickly and efficiently covered and insulated generally without the need for special installation tools. ## Claims ### Claim 1 An insulative cover assembly for insulating a P-trap drain piping assembly located under a sink including a straight pipe, a J-shaped pipe, and an L-shaped pipe joined together at junctures by pipe nuts, the cover assembly comprising: a unitary body including a first section and a second section joined together at a third section, the first section having body configured to cover a pipe and having a first end, end the second section having a body configured to cover a pipe and having a first end; the third section coupling second ends of each of the first and second sections together to form said unitary body, the third section comprising a structurally weakened area therein which is manually separateable for thereby separating the second ends and forming first and second cover pieces from said unitary body, said structurally weakened area comprising a plurality of perforations extending in a generally circumferential line around the unitary body between the first and second sections; the first and second sections each including a longitudinal slit thereon for being spread apart and positioned over the pipes when separated into first and second cover pieces; whereby the piping assembly is quickly and efficiently covered and insulated generally without the need for special installation tools. ### Claim 2 (depends on 1) The insulative cover assembly of claim 1 wherein said first cover piece first end includes an approximately 180.degree. bend portion. ### Claim 3 (depends on 1) The insulative cover assembly of claim 1 wherein said second cover piece first end includes an approximately 90.degree. bend portion. ### Claim 4 (depends on 1) The insulative cover assembly of claim 1 wherein said second cover section comprises an end portion for coupling with an end portion of the first cover section when the unitary body is separated into the first and second pieces and positioned on the pipes of the undersink assembly whereby to generally completely cover the undersink assembly. ### Claim 5 (depends on 4) The insulative cover assembly of claim 4 wherein the end portions are configured to abut with each other when the first and second cover pieces are installed on the drain piping assembly. ### Claim 6 (depends on 4) The insulative cover assembly of claim 4 wherein an end portion of one of said first and second cover pieces comprises a structurally weakened area which is manually separateable for removing part of the end portion to vary the length of said end portion. ### Claim 7 (depends on 6) The insulative cover assembly of claim 6 wherein the structurally weakened area of the end portion comprises a sidewall area extending circumferentially therearound and having a second thickness which is less than a first thickness of the end portion for manually separating part of the end portion. ### Claim 8 (depends on 6) The insulative cover assembly of claim 6 wherein the structurally weakened area of the end portion comprises a plurality of perforations extending in a generally circumferential line around the end portion, a part of the end portion being manually separateable along said perforation line. ### Claim 9 An insulative cover assembly for insulating a pipe of a P-trap drain piping assembly located under a sink, the cover assembly comprising: a body including a first section and a second section joined together at ends thereof at a third section, the first and second sections each configured for covering respective pipes of the undersink assembly; the third section comprising a structurally weakened area therein which is manually separateable for thereby separating the ends of the first and second sections and forming first and second cover pieces from said unitary body which may be positioned over respective pipes, said structurally weakened area comprising a plurality of perforations extending in a generally circumferential line around the unitary body between the first and second sections; whereby the piping assembly is quickly and efficiently covered and insulated generally without the need for special installation tools. ### Claim 10 (depends on 9) The insulative cover assembly of claim 9 wherein said first and second cover pieces each include a longitudinal slit formed therein for being spread apart to position the pieces over the respective pipes. ### Claim 11 (depends on 9) The insulative cover assembly of claim 9 wherein the first section has an elongated body terminating in an approximately 180.degree. bend at another end of said first section, and the second section has an elongated body terminating in an approximately 90.degree. bend at another end of said second section. ### Claim 12 (depends on 9) The insulative cover assembly of claim 9 wherein one of said first and second cover pieces comprises an end portion for coupling with a portion of the other of said pieces when the first and second pieces are positioned over the pipes. ### Claim 13 (depends on 12) The insulative cover assembly of claim 12 wherein said end portion comprises a structurally weakened area which is manually separateable for removing part of the end portion to vary the length of said end portion. ### Claim 14 (depends on 13) The insulative cover assembly of claim 13 wherein the structurally weakened area of the end portion comprises a side wall area extending circumferentially therearound and having a second thickness which is less than a first thickness of the end portion for manually separating part of the end portion. ### Claim 15 (depends on 13) The insulative cover assembly of claim 13 wherein the structurally weakened area of the end portion comprises a plurality of perforations extending in a generally circumferential lien around the end portion, a part of the end portion being manually separateable along said perforation line. ### Claim 16 An insulative cover assembly for insulating a pipe of a P-trap drain piping assembly located under a sink, the cover assembly comprising; an elongated body having opposing ends, said body terminating in one of an approximately 180.degree. bend and an approximately 90.degree. bend at an end of said body section; the body further comprising an end portion positioned at an end thereof, the end portion including a structurally weakened area for forming a circumferential part of said end portion which is manually separateable from the end portion for adjusting the length of the body for proper fit on a respective pipe when installed thereon, the structurally weakened area comprising a series of perforations extending in a circumferential line around the end portion, whereby the pipe of the piping assembly is quickly and efficiently covered and insulated generally without the need for special installation tools. ### Claim 17 (depends on 16) The insulative cover assembly of claim 16 further comprising a plurality of structurally weakened areas for separating circumferential parts at discrete lengths along the end portion for selectively varying the length thereof.
