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.

In certain aspects, devices and methods for moving a toilet are provided that can include an elongated member, a first engaging member, and a second engaging member. The engaging members can be coupled to the elongated member and extend radially away from the elongated member. The engaging members can include contact surfaces that are disposed distal to the elongated member and that are configured to engage the toilet. In other aspects, devices and methods for moving a toilet can include a handle, a first collar, and a second collar. The collars can be coupled to the handle and can be configured to slide along the handle in unlocked modes and to positionally secure along the handle in locked modes. The collars can be configured to receive and secure to one or more removable shackles.

Embodiments described herein relate to quick release toilet concepts, which can be useful particularly on-board aircraft and other passenger transport vehicles. Further embodiments relate to improved shroud components for toilets that help reduce splash. Further embodiments also relate to flushing systems for use with vacuum toilets.

A toilet flange cap with cleaning basin is presented. The toilet flange cap with cleaning basin contains a cap body and a flange seal. The flange seal is connected adjacent to the cap body. The toilet flange cap with cleaning basin allows a user to plug and seal a flange aperture along a toilet flange insert, preventing sewage gas and airborne pathogens from emitting from the flange aperture.

An apparatus for continuously controlling fluid flow in a sewer conduit, comprising: a) moisture sensors detecting levels of fluid in this conduit; b) an inflatable bladder, mounted in the sewer conduit for releasably sealing in fluid tight fashion a section of this conduit; a compressed air source for inflating the bladder; and a control box including a CPU sensitive to the moisture sensor(s) and actuating the air compressor responsively to conduit fluid level conditions reaching beyond a preset threshold value. The performance of the apparatus is independent of the speed of fluid flow in the sewer conduit.

The present invention provides an in-line valve particularly suitable for draining facilities to avoid odour penetrating habitable spaces or backflush of drainage liquids. The in-line valve comprises a body, preferably made of two engageable parts, an inset and a duckbill valve. The insert is located within the valve body and surrounding the duckbill valve. The insert funnels liquid from the valve inlet to the valve outlet, so that puddling in the valve body is avoided and therefore no water is accumulated, which could lead to odours or microorganisms proliferation.

A rail vehicle includes a graywater line which is in communication with the surroundings of the rail vehicle directly or by way of a collecting container. The graywater line is equipped with a pressure protection valve, which protects a graywater line section upstream of the pressure protection valve from pressure surges occurring in the surroundings of the rail vehicle. The pressure protection valve is constructed as a pinch valve which is controlled by a control device in order to protect the graywater line section from pressure surges.

The embodiments disclosed herein are directed towards vacuum-assisted toilet systems and methods of using the vacuum-assisted toilet systems. An example vacuum-assisted toilet system includes a toilet bowl defining an outlet and a flush valve fluidly coupled to the outlet. The vacuum-assisted toilet system also includes at least one water source fluidly coupled to the toilet bowl. The water source is configured to supply water to the toilet bowl. The vacuum-assisted toilet system also includes at least one water actuator coupled to the water source. The water actuator is configured to control the amount of water that is supplied by the water source to the toilet bowl. The vacuum-assisted toilet system also includes a controller that is configured to at least partially control the operation of one or more components of the vacuum-assisted toilet system, such as at least one of the flush valve or the water actuator.
