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 shower system includes a shower waterway and a fluid control valve. The shower waterway is configured to be coupled to a shower device. The fluid control valve is coupled to the shower waterway and comprises a valve body and a piston. The valve body includes a chamber and a reservoir. The piston is slidably coupled to the valve body and fluidly separates the chamber from the reservoir. The chamber includes a compressible gas. The piston is configured to slidably translate within the valve body to compress the compressible gas in response to a water pressure fluctuation in the shower waterway.

A clean water system includes at least one water tank including water, a plurality of water consuming devices coupled to the water tank, and an automatic dispenser. The automatic dispenser is configured to automatically discharge a predetermined amount of a cleaning compound into water of at least on water tank, wherein the cleaning compound is distributed to the plurality of water consuming devices.

Systems, methods, and articles of manufacture for automatic backflow identification, detection, remediation, and/or management. In some embodiments, a backflow management device may comprise a threaded and electronically-enabled plug installed in a non-pressurized pipe system cleanout, branch, or stub.

A bathroom module includes a shower area that includes a shower head, a control valve assembly, and a drain. The module also includes a toilet area including a toilet assembly and a transition area disposed between the shower area and the toilet area. The module also includes a shower area front wall and a shower area side wall, the shower area disposed along a first side of the shower area front wall and a first side of the shower area side wall. The module also includes a toilet area front wall and a toilet area side wall, the toilet area disposed along a first side of the toilet area front wall and a first side of the toilet area side wall. A grooming area includes a sink assembly that comprises a faucet, and the grooming area is disposed along a second side of at least one of the shower area front wall, the shower area side wall, the toilet area front wall, and the toilet area side wall.

A shower system includes a shower waterway and a fluid control valve. The shower waterway is configured to be coupled to a shower device. The fluid control valve is coupled to the shower waterway and comprises a valve body and a piston. The valve body includes a chamber and a reservoir. The piston is slidably coupled to the valve body and fluidly separates the chamber from the reservoir. The chamber includes a compressible gas. The piston is configured to slidably translate within the valve body to compress the compressible gas in response to a water pressure change in the shower waterway.

A drain box having a housing, a splash containment therein with a lower portion within a housing drain aperture, and a discharge conduit having a lower portion positioned within the splash containment in position above the drain aperture and extending upward through splash containment aperture, and an upper portion extending upward through a housing upper aperture and terminating above the housing upper portion for connection to an appliance discharge conduit. The conduit being attached to the housing to prevent a lower discharge conduit end from moving downward toward the drain aperture to less than a predetermined minimum distance above the housing drain aperture.

A backflow prevention system and apparatus is disclosed. The system includes a pipe designed to couple to a washer. The backflow prevention apparatus includes a housing and two one-way valves. The housing secured to the pipe. A first one-way valve is coupled to the housing, with the first one-way valve defining a first cross-slit. A second one-way valve is coupled to the housing and spaced from the first one-way valve, with the second one-way valve defining a second cross-slit. The first one-way valve and the second one-way valve are designed to allow fluid flow, through the housing, in a first direction and prevent flow of suds, foam, gas, or combinations thereof in a second direction opposite the first direction.

An air odor removal system with sewage or septic plumbing attachment removes odors from a stand-alone structural housing, such as a litter box or toilet bowl. The air odor removal system includes a first odor conduit assembly that is fluidly coupled, from one end, to the structural housing, and from an opposing end to an air mover device that creates a vacuum in the first odor conduit assembly. A motion sensor detects a motion event at the structural housing, and signals the air mover to power on. A second odor conduit assembly carries the odor from the air mover device to a one-way valve. A sewage plumbing conduit carries the odor from the one-way valve, and fluidly couples to a sink and a sewage storage, where the odor is finally discharged. The sewage plumbing conduit comprises a generally U-shaped pipe that restricts the odor from flowing to the sink.

The present inventive concept relates to a system (100) comprising: a water recirculating device comprising: a heating arrangement (112) arranged in a recirculating path (108); a mixing valve arrangement (122) in liquid communication with an external ON water path arrangement (114), said mixing valve arrangement (122) accepting as inputs hot and cold water from a hot and cold water source respectively, said mixing valve arrangement (122) being configured to form temperature regulated water (120) by combining said hot and cold water, said mixing valve arrangement (122) comprising a user input interface configured to control a proportion of said hot and cold water directed to said external water path arrangement (114); and a reference temperature determining arrangement (130) configured to determine a reference water temperature of said temperature regulated water (120); wherein said heating arrangement (112) is configured to adjust a water temperature of treated water towards said reference water temperature.
