Example lavatory waste tube connection systems and related methods are discoed herein. An example apparatus includes an extension tube to be coupled to a system waste tube and a junction box to be coupled to a surface of a vehicle lavatory. The junction box is to define a housing for the extension tube.

A toilet assembly includes a toilet, a non-vitreous fluid delivery component, and a connector assembly. The non-vitreous fluid delivery component is coupled to, and in fluid communication with, the toilet. The connector assembly couples the non-vitreous fluid delivery component to the toilet in a substantially watertight manner. The connector assembly includes a connector body, a nut adjustably coupled to the connector body, and a sealing member disposed on the connector body. The nut is configured to be adjusted relative to the connector body to cause the connector body to compress the sealing member against a portion of the toilet, such that the sealing member creates a substantially watertight seal between the toilet and the connector body.

A rinse ring system for use on a toilet. The rinse ring is a dual channel rinse ring, which allows the toilet to be flushed with either potable water from a fresh water system or with grey water from a grey water source. Other flush fluids are possible for use. The dual channel rinse ring provides separation between entry points for potable water rinse and the grey water rinse, preventing the possibility of contamination of the potable water source with grey water.

A toilet includes a tank, a pedestal, and a mounting assembly. The tank includes a bottom wall. The bottom wall includes an opening and a bottom surface. The pedestal includes an opening and a top surface. The opening of the pedestal is aligned with the opening of the bottom wall. The mounting assembly includes a mounting plate, a nut, and a gasket. The mounting plate is configured to be coupled to the pedestal and includes an opening aligned with the opening of the pedestal. The nut holds the mounting plate against the bottom surface of the bottom wall and includes a rounded portion. The gasket is disposed about the opening of the pedestal and along the top surface of the pedestal and includes a concave surface that is configured for receiving the rounded portion of the nut.

A toilet for measuring excreta is disclosed. The toilet is adapted to measure the amount of excreta received by the bowl and then the flush water. A pressure sensor is configured to monitor the pressure exerted by the flush water and any excreta contained therein. Data from monitoring the pressure of the flush water and excreta therein is used to determine the weight or volume of the excreta received by the bowl. This toilet can provide data which may be used to analyze how the volume of flush water changed due to excreta deposit. A volume change feature can be associated with a urination event and the data associated with the event can be used to determine a urine characteristic of the event.

An air exhaust apparatus for use in conjunction with a flush toilet system having a rinsing liquid source and a toilet bowl configured with a rinsing inlet and a waste outlet. The air exhaust apparatus having: a housing constituting a gas tight space, a flushing conduit extending through the housing and having a front portion couplable to the rinsing inlet, and a rear portion couplable to the rinsing liquid source; the flushing conduit is configured with a suction opening disposed within the gas tight space. The suction opening is fitted with a liquid flow prevention mechanism configured for preventing rinsing liquid from flowing into the gas tight space during rinsing liquid flow towards the toilet bowl through the flushing conduit. A waste conduit extends through the housing and having a front portion couplable to the waste outlet, and a rear portion couplable to a sewage line; the waste conduit is configured with a gas discharge port disposed within the gas tight space. A gas propelling unit is disposed within the gas tight space and being in flow communication with the gas discharge port and configured to selectively propel gas in direction from the suction opening towards the gas discharge port and a gas flow valve is configured to selectively propel gas in a direction between the suction opening and the gas discharge port when the gas propelling unit is active.
