Abstract: A drain system for transporting waste from a vehicle to a discharge location located spaced from the vehicle may include first, second and third modular components. The first modular component may be adapted to coupling to the vehicle and may define a first male connection. The second modular component may include a waste transfer portion extending between a first end and a second end. The first end may define a first female connection and the second end may define a second male connection. The third modular component may include an angled central portion, a first end and a second end. The first end may define a second female connection. The second end may define a waste discharge end. The drain system may further include a fourth modular component defining a first end having an opening for receiving the waste discharge end of the third modular component and a second end for interfacing with a tubular intake of the discharge location.

Abstract: A flush toilet includes a base and a bowl assembly defining a bowl. The bowl assembly is mounted to the base and defines a discharge opening at a lower end of the bowl. A waste ball valve assembly is mounted to the flush toilet for selectively opening and closing the discharge opening of the bowl assembly. A common sealing member operates to seal the bowl to the base and to wipe a ball of the waste ball valve assembly as the waste ball valve assembly is selectively opened and closed. The common sealing member has a generally horizontal portion for wiping the ball of the ball valve assembly and a compressible cylindrical portion upwardly extending from the generally horizontal portion. The cylindrical portion is compressed between the base and the bowl to define a seal therebetween.

Abstract: A control system for a flush toilet includes a water delivery device for delivering a source of flush water to a bowl. The control system includes a controller and a user interface. The controller is operative to control the toilet through a flush sequence in a first mode and a second mode. In the first mode, the controller opens the water delivery device to deliver a predetermined amount of water to the bowl. In the second mode, the controller opens the water delivery device to deliver a user adjustable amount of water to the bowl. The user interface is in communication with the controller for selecting between the first mode and the second mode. Where the toilet is a macerator toilet, the controller monitors current draw unit when the current draw satisfies a predetermined current condition. The controller may operate in a normal mode and a lockout mode.

Abstract: A pump assembly includes a housing defining a working chamber, a water pump chamber and a waste pump chamber. A first diaphragm separates the water pump chamber and the working chamber. A second diaphragm separates the waste pump chamber and the working chamber. A common driver member interconnects the first diaphragm and the second diaphragm. Movement of the driven member to a first position creates a positive pressure in the water pump chamber and a negative pressure in the waste pump chamber. Movement of the driven member to a second position creates a negative pressure in the water pump chamber and a positive pressure in the waste pump chamber.

Abstract: A macerator toilet comprising a toilet body include a bowl portion and a base portion, the base portion defining a chamber and a macerator unit in fluid communication with the bowl portion, the macerator unit completely disposed in the chamber and operative for macerating a waste received from the bowl unit and pump the waste from the macerator toilet.

Abstract: A flush toilet includes a bowl assembly defining a bowl. The bowl assembly has a discharge outlet at a lower end and a ledge circumferentially extending about a substantial portion of the bowl. The bowl has a rear surface that is generally flat and vertical. The rear surface transitions to the ledge as the bowl continues clockwise and counter clockwise from the rear surface. A horizontal dimension of the ledge increases as the ledge continues from the rear surface to a front of the bowl. An angle of the ledge increases as the ledge continues from the rear surface to the front. A maximum slope of the ledge is located proximate the front. A nozzle is mounted to the bowl assembly for pressurizing a source of flush water and delivering the source of flush water to the bowl for rinsing and flushing of the bowl.
