A portable liquid dispensing station for outdoor use in cold temperatures comprises a housing defining a base for resting on a support surface and enclosed interior thereover, at least one liquid storage tank supported inside the housing for containing unused liquid, a pump supported inside the housing in fluidic communication with the tank for conveying the unused liquid under pressure to a downstream location, a liquid dispensing device supported externally of the housing but in downstream fluidic communication with the tank for selectively releasing the liquid, a basin supported externally of the housing for collecting the released liquid, and a collection tank in fluidic communication with the basin to collect the used liquid for storage and which is supported inside the housing. The liquid dispensing device, the basin and the collection tank are heated and the air inside the housing is also heated to prevent the liquid from freezing.

A water drain management apparatus used in clinical facility (43) or other facility includes a manifold plumbing fitting (32, 272, 384). The fitting includes a plurality of drain outlet connections for water discharge devices (40, 42, 222, 226, 230, 234). Such water discharge devices may include devices such as autoclaves, sterilizers, cleaners, washers, filters, humidifiers, condensing devices and other devices used in the facility. A plurality of drain fitting openings in the body of the fitting are connectable to respective water discharge devices, and openings that are not utilized are closable with plugs. Some manifold fittings (272, 344, 384, 482) include an air gap opening (288, 360, 392, 530). These configurations provide an air gap that prevents contamination due to back flow of water within the fitting reaching water discharge devices or the body inlet of the manifold fitting.

An apparatus for reducing emulsions in kitchen effluent discharging to a FOG removal apparatus includes a pre-rinse sink, a tank positioned below the pre-rinse sink to receive effluent from the pre-rinse sink, an outlet from the tank and leading to a pipe, a valve in the outlet having an open position and a closed position, a dishwasher having a drain connected to the pipe, and a control for the valve to be in its closed position when the dishwasher is discharging to the pipe.

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.

An insert, which can be installed as an odor stopper in the drain area of a household installation, e.g., in a drain pipe, includes a cylindrical area, which has a flange that projects outward. The insert also includes a closure area with an elastically deformable wall part. In the closure position, the wall part of the closure area rests against an opposite wall of the insert. In this case, the free edge of the wall part rests against the opposite wall from inside, creating an odor stopper. When water flows through the drain pipe, the wall part of the closure area is moved away from the opposite wall by the draining water, so that the closure area is opened. As soon as no more water flows through the insert, the wall part of the closure area again rests against the opposite wall, so that the odor stopper is created.

A thermal recovery device for recovering waste heat from a sink having a bottom plate, the bottom plate having a top surface and a bottom surface, wherein the bottom plate being a thermal conductor, the thermal recovery device including: a tube including an inlet and an outlet, the tube thermally connected to the bottom surface, wherein thermal communication exists between the top surface and a fluid in the tube, a demand for the fluid causes the fluid to flow through the tube and heat transfer to the fluid which raises the temperature of the fluid prior to entering a heater and subsequently arriving at the top surface of the bottom plate of the sink from which the heat is transferred, reducing the heating load of the heater due to the demand of the fluid.
