A system for hands-free collection of biomaterials, such as urine, in a vessel disposed below a closable port, the vessel being sealable by an at least partially automated sealing mechanism, the sealed vessel being transferable to a storage area. In general terms this application is directed to a hands-free, biomaterial collection system that is it least partially automated. In one aspect, a biomaterial collection system comprises a biomaterial capture area including a port, a collection area disposed below the capture area, a vessel disposed in the collection area and aligned with the port, and a sealing mechanism disposed in the collection area for sealing the vessel.

A toilet includes a bowl including a supply water plenum providing the water to the basin, a primary drain fluidly connecting and terminating at a drain passage and a secondary drain fluidly connecting the supply water plenum to the sewer drainage pipe. The secondary drain is separate from the primary drain and includes at least one secondary drain inlet that is disposed within the supply water plenum, a second drain channel, and a second drain outlet. The inlet permits rising waste water to flow from the supply water plenum into the second drain channel and out of the second drain outlet to the sewer drainage pipe separately from the waste water of the primary drain. The supply water plenum also includes a diverting wall located upstream of the secondary drain inlet configured to divert water flowing from upstream from flowing into the inlet.

A toilet with a flushable overflow drain includes a bowl and a primary drain connected to the bowl to receive fluid therefrom and having a primary drain trap. An overflow drain including an overflow drain trap is connected to the bowl at one end thereof and is connected at a second end to the primary drain at a location downstream of the primary drain trap. An overflow drain flush passage is connected to the overflow drain at a position upstream of the overflow drain trap. Accordingly, water can be directed through the overflow drain flush passage and into the overflow drain to flush the overflow drain and the overflow drain trap free of debris to prevent clogging.

A microprocessor-operated, networked device that uses sensors in, on and near the toilet to detects toilet leaks and overflows of the toilet tank or bowl, then reports these errant conditions with a visual or audible indicator in addition to sending a message via a network (if available) to a computer system that may collate this data with that from other toilets and other sources and subsequently determine further action such as shutting off water or calling a technician. The present invention can be integral to a toilet or removably attached to an existing toilet without this technology.

An improved plunger having a true arch configuration and defining an interior cavity provides a body having a convexly dome shaped upper portion and a rectilinear truncated conic shaped bottom portion that defines a bottom orifice. Axial downward pressure exerted or a handle communicating with a handle attachment carried by the dome shaped upper portion causes the body to collapse to forcefully expel contents of the interior cavity outwardly through the bottom orifice and into a pipe or plumbing fixture. A flexible resiliently deformable exterior lip circumscribing the bottom orifice prevents leakage and the truncated conic shape of the bottom portion fluidically seals a toilet siphon jet to prevent loss of plunger pressure when removing clogs and obstructions.

A wall hung toilet is described which has a toilet body having a toilet body inlet, a back plate having at least a first and a second lower fastener opening therethrough, a toilet body outlet, a bowl and a base. The bowl has an interior surface defining a interior area for receiving fluid, an inlet for introducing fluid to the interior area of the bowl and a bowl outlet. A trapway for passing fluid from the bowl outlet to the toilet body outlet is also included. The base of the toilet body extends from a front bowl portion of the base to a rear portion of the base that contacts the back plate, and the base is configured so as to distribute load bearing forces when applied to the bowl in use towards each of a first area around the first fastener opening and a second area around the second fastener area.

A toilet configuration includes a toilet fixture, a detachable primary drain, and a detachable secondary drain. The primary and secondary drains can be assembled together or formed unitarily. The fixture includes a toilet bowl, a primary drain interface at a bottom of the bowl configured to permit liquid to flow from the toilet bowl into a detachable primary drain, and a secondary drain hole. The detachable primary drain fluidly is connected to the primary drain interface and is configured to be fluidly connected to a sewer pipe to discharge the liquid directly into the sewer pipe. A detachable secondary drain fluidly is connected to the secondary drain hole and is configured to be fluidly connected to the sewer pipe to discharge backed up fluid from the toilet fixture directly into the sewer pipe.
