A trap is formed from two instances of a standard part, the ninety degree elbow, and a two-part ninety degree elbow that has a cross-section that runs from circular at the upstream spigot to ovoid at the juncture of the two parts back to circular at the downstream hub. All of the rules that bind trap design in building codes can still be accommodated in this trap architecture. Moreover, the ability of the critical flattened elbow part to be formed from two plastic parts with standard line-of-draw cores reduces entry cost of fabrication. Access to the interior of the parts also allows for novel internal coating strategies. Most importantly for installation, the height of whole trap is reduced by squishing the trap diameter to a degree that a significant drop in trap height is achieved. This decrease in trap height can be sufficient to allow the trap to be accommodated in the reduced height of a vertical space between an underlying ceiling and the underside of the lowered subfloor.

A system of pipe insulating sleeves includes a series of elastomeric foam insulating sleeves that are capable of opening up to, and beyond, 180 degrees, to accommodate and capture an undersink pipe. The disclosed system may include a number of different sleeves that are capable of coupling to one another at respective couplers so as to form the system. The sleeves may include fastening mechanisms to retain the sleeves in the closed configuration while capturing the pipe, so as to create a smooth, streamlined appearance that is aesthetically pleasing. Also disclosed is a method of installing the sleeves. The sleeves are made of an elastomeric foam material that has heat insulating properties, and which may also have antibacterial and antimicrobial properties that make it particularly advantageous for use in undersink pipe insulating.

A plumbing trap assembly for plumbing a condensation drain line into a sewer line includes a P-trap that is plumbed into a drain line of a sink. The P-trap has an inlet, an outlet and a lower bend that is positioned between the inlet and the outlet. The inlet is fluidly coupled to a drain of the sink and the outlet is fluidly coupled to a sewer line servicing the sink such that the lower bend forms a trap for sewer gasses. A condensation inlet is integrated into the P-trap thereby facilitating the condensation inlet to be fluidly coupled to a condensation drain line of an air conditioning unit. In this way condensation from the air conditioning unit can be drained into the sewer line which services the sink.

Drain pipe assemblies are provide that include a first flexible pipe having a first end, a second end, and a plurality of convolutions formed therein. A first female threaded connector is provided that is configured to receive one of the convolutions of the first flexible pipe therein. In this way, the first female threaded connector can form a seal when the one of the convolutions received therein is proximate the first end of the first flexible pipe and the first female threaded connector is threadably coupled to a first male threaded coupling. A retainer is provided that is configured to dispose a portion of the flexible pipe therethrough to form and retain a trap in the first flexible pipe. Methods of installing and using such drain pipe assemblies are also provided.

A pipe coupling assembly for coupling a first end portion of a first pipe with a second pipe includes a socket formed on an end of the second pipe and a locking ring. The socket includes a rim defining an end opening through which at least a portion of the first end portion is inserted, the rim including a rim sealing surface adapted to form a liquid-tight seal around the first end portion. The socket also includes a sleeve portion having an exterior surface and an interior surface defining an interior space for receiving the first end portion, the interior surface comprising at least two socket sealing surfaces adapted to form a liquid-tight seal around the first end portion. The locking ring is adapted to cause the rim sealing surface to compress to form a liquid-tight seal around the first end portion.
