A joint device for drain pipes comprises a structural tube made of a rigid material and providing structural integrity to the joint device. The structural tube defines at least part of a drain passage of the joint device, a bottom portion of the structural tube having diametrical dimensions for complementary sealing engagement with a pipe of a drain network. An annular seal of resilient sealing material is integrally connected to an upper portion of the structural tube to define at least an inner surface of a portion of the drain passage of the joint device, the annular seal having inner diametrical dimensions for sealing engagement with a tailpiece slid downwardly into engagement with the joint device.

An apparatus includes a manifold heat exchange fitting (32) configured to collect a plurality of fluid streams of fluids having different fluid densities. The fitting includes a body (52) with a generally open fluid collection interior area (56). The body of the heat exchange fitting is positioned in a central fluid path that includes a body inlet (58) and a body outlet (60). A plurality of fluid stream fitting openings (76) in the body are connectable to fluid streams of fluids having different densities delivered from water discharge devices such as an autoclave, a steam sterilizer in the steam cooler. The fluid streams of the fluids having different densities collected in fluid communication in the fluid collection interior area may undergo heat exchange prior to discharge from the body outlet.

A connector apparatus featuring a main pipe with first and second opposed ends. Each has a corresponding male-threaded fastening section for mating with the complimentary female-threaded fastening section on a respective conventional pipe-locking ring or collar. A valve-housing for supporting a one-way flow valve assembly interiorly, and a riser mounted on and supported by the valve housing for ultimate connection to the output or exhaust nozzle of a medical scavenger device.

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 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 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.
