A waste system of a height adjustable toilet comprising a fixed frame with a vertically mounted sliding plate thereon, wherein the waste system comprises a piping system with a series connected upper pipe, an upper elbow, a connecting pipe, a lower elbow, and a lower pipe, wherein the upper sleeve is fixed to the sliding plate and the lower sleeve is attached to the fixed frame, the upper elbow on the upper sleeve and the lower elbow on the lower sleeve being seated freely pivotable about their axial axes and the connecting pipe being made of elastically flexible material.

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 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 device for a rail vehicle includes flushing water-carrying installations and wastewater-carrying installations. The flushing water-carrying installations include an intermediate reservoir for storing flushing water and a supply line for supplying the intermediate reservoir with flushing water. The supply line includes a filter for filtering the flushing water supplied to the intermediate reservoir. The supply line is connected to the intermediate reservoir such that flushing water from the intermediate reservoir can be returned through the filter. A backflushing line is connected to the filter and opens into a wastewater-carrying installation. A method for operating the toilet device includes supplying the flushing water through a filter to fill the intermediate reservoir, and flushing a flushable bowl with flushing water from the intermediate reservoir or backflushing the filter with flushing water from the intermediate reservoir and draining off the flushing water to a wastewater-carrying installation.

A toilet includes a bowl having an opening, an outlet, and two jet holes positioned above a water line defined by a weir of a trapway. The two jet holes are configured to evacuate waste from the bowl into a drain.

A toilet system with a toilet base including a toilet bowl and a shroud for covering a plumbing riser located at a rear end of the toilet base that provides ligature-resistance for institutional applications. The shroud has a mating feature that joins with a corresponding feature at a rear portion of the toilet base to prevent formation of a gap between the base and a front of shroud in at least at a top side of the area of contact between the shroud and the back of the toilet base. The mating feature can be provided by forming a rectangular cross-section at the rear of the toilet base and providing a matching aperture through the shroud. A toilet seat, which may be bonded or bolted to toilet base has an outer edge that is chamfered to prevent ligature formation around a portion of toilet seat.
