The roof cover vent system comprises a vent sheath, a flange sheath, and a pitched roof. The pitched roof further comprises a roof vent and a roof pitch. The vent sheath attaches to the flange sheath to form a composite prism structure. The roof vent inserts into the composite prism structure formed by the vent sheath and the flange sheath. The composite prism structure formed by the vent sheath and the flange sheath enclose the lateral face and the inferior structures of the roof vent while allowing the roof vent to release gas into the atmosphere. The flange sheath is formed as a prismatic section. The prismatic section is selected such that center axis of the composite prism structure formed by the vent sheath and the flange sheath will remain parallel to the force of gravity while the flange sheath rests flush on the pitched roof.

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 flushometer including a sanitation unit is described herein. The sanitation unit may be configured to emit ultraviolet light in response to the flushometer effectuating a flush of the fixture. The ultraviolet light may sterilize and/or sanitize a plume caused as a result of the flush. The ultraviolet light may be emitted for a predetermined amount of time to sterilize, sanitize, and/or kill any pathogens contained in the plume. Additionally or alternatively, the sanitation unit may emit the ultraviolet light periodically. For example, the sanitation unit may emit the ultraviolet light in response to receiving one or more signals from a gateway and/or server. The sanitation unit may provide an environmentally friendly solution that reduces water consumption and/or cleans, sanitizes, and/or sterilizes plumbing fixtures, toilet seats, etc. between uses without the need for harsh chemicals and/or cleaning solutions.

A sink system includes a sink basin and a disposal system. The disposal system includes a first inlet coupled to the sink basin, a second inlet fluidly coupled to a second fluid source, and a garbage disposal configured to receive a first flow of fluid from the sink basin via the first inlet and receive a second flow of fluid from a second fluid source via the second inlet. The sink basin delivers a flow of used water to the disposal system and the second fluid source delivers a flow of clean water to the disposal system.

An apparatus senses the proportion of FOG flowing with effluent from a sink to a p-trap. A pipe portion is connectable for use as a tailpipe for a sink with a first electrode within the pipe portion and a second electrode outside the pipe portion. Conductors connect the first and second electrodes to a capacitance sensor, so changes in capacitance between the electrodes caused by changes in proportions of FOG content in effluent from the sink can be detected and/or monitored. The monitoring can be remote and can cause an action when an excess FOG content is detected.
