Toward the enabling of cleaning schedules involving one or more chemical treatments for the disinfection of healthcare room sink drainsets to avoid nosocomial infections arising from the vectoring of drain pathogenic bacteria, a blockable novel connector is presented to connect a sink drainset to an existing wall stub leading to a drainage stack behind the wall. Multiple chemical soaks for the drainset can be enabled through elaboration of the blocking plug temporarily inserted into the adapter. Two configurations, sideways and upward, are possible to connect the wallbend straight to the connector, the upward allowing for orthogonal connection between the straight and the receiving hub of the connector whatever the angle an existing wall stub has to the wall upon which the sink is hung. Additional blocking plug technology can be enabled.

An accumulator assembly having a wastewater retention tank defining an interior chamber. A fluid level sensor is coupled to the waste retention tank and configured to sense a level of liquid in the chamber. An extraction pipe extends into the chamber and is coupled to an extraction valve. Coupled to the fluid sensor is a controller that is also coupled to the fluid level sensor and to the extraction valve. The controller is configured to open the extraction valve upon receipt of a signal from the sensor. The accumulator assembly also includes an odor mitigation subassembly in fluid communication with the chamber. The odor mitigation subassembly further includes an air displacement port, an odor filter and an overflow prevention device, the overflow prevention device being in fluid communication with the chamber and located downstream of the air displacement port and upstream of the filter.

A fluid waste filtration system includes a housing configured to be coupled between and in fluid communication with a sink and a primary grease trap. The housing defines a chamber and includes a fluid inlet, a fluid outlet, and a grease outlet each in fluid communication with the chamber. The grease outlet is defined in a plane at or above a plane of the fluid outlet. A wall is disposed in the housing and divides the chamber into a first chamber and a second chamber. The wall is configured to direct a fluid that flows into the first chamber through the fluid inlet toward the grease outlet.

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 preassembled modular vacuum plumbing assembly for attaching a plumbing fixture to a water supply system and to a vacuum-assist waste removal system includes a frame having two upright members and at least one connecting member between the two upright members. At least one water supply conduit is attached to the frame, each water supply conduit having a first end configured for attachment to the water supply system and a second end configured for attachment to the plumbing fixture for providing water from the water supply system to the plumbing fixture. An accumulator is associated with the plumbing fixture for receiving and holding water provided by the at least one water supply conduit to the plumbing fixture. A wastewater outlet conduit is attached to the frame, the wastewater outlet conduit having a first end attached to the accumulator and a second end configured for attachment to the vacuum-assist waste removal system for directing water from the accumulator to the vacuum-assist waste removal system.

A biofilm mitigation apparatus includes a supply container, a disinfectant generator, a power source, and a delivery tube. The supply container is configured to store one or more materials for a formation of a disinfectant. The disinfectant generator is configured to generate the disinfectant from the one or more materials from the supply container. The power source is configured to provide electrical power to the disinfectant generator. The delivery tube is configured to transport the disinfectant from the disinfectant generator to a biofilm.

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.

A compact residential house is disclosed which includes a pre-fabricated installation panel serving as an outer wall of the residential house and a lifeline system pre-installed on an outer surface of the pre-fabricated installation panel, the lifeline system including a grey water system.

Disclosed is a method for water saving by retrofitting an institutional plumbing fixture having a combination of an integral lavatory basin and a toilet bowel integrally attached thereto by inserting into the fixture a urinal-type collection receptacle having a water inlet opening on its top side and a water outlet opening on its bottom side; and fluidly interposing the receptacle via the inlet and outlet openings between the lavatory drain pipe and the drain trap provided for the plumbing fixture. Also disclosed is an institutional plumbing fixture retrofit for water saving, and a retrofit urinal-type receptacle.

This safety clean-out cap system provides for the removal of water and debris from drains. It consists of a flow channel that is mounted within the opening of a clean-out cap. The flow channel is diametrically opposed to the top surface of the clean-out cap and bends at a 90-degree angle just below a rectangular recess. The rectangular recess has a grab portion that cooperatively receives a tool. Additional embodiments of the safety clean-out cap system include clean-out caps having channel extensions and a square-shaped channel. The channel extensions extend at a 180-degree angle from the clean-out cap and have a plurality of longitudinal rails and longitudinal plates that further facilitate the removal of the clean-out cap from drainpipes. The clean-out cap and the additional embodiments are attached to fittings, pipe sections and hose sections in order to regulate the flow of water and debris from a drain.
