A flush toilet resting over a floor and comprising: a toilet bowl; a first water conduit comprising a first conduitfirst end and a first conduitsecond end; a second water conduit, comprising a second conduitfirst end and a second conduitsecond end, and; at least one water pump, the at least one pump water-powered and not electrically powered; wherein: the first conduitfirst end is operationally connectable to an external water pipe comprising pressurized water; the first conduitsecond end is positioned to allow providing the pressurized water to the water pump; the second conduitfirst end is operationally connected to receive water from the water pump; wherein the water pump is positioned proximal to the bowl and between the bowl and the floor, and wherein the toilet is configured such that action of water on the at least one pump allows the flush of at least 6 liters per second.

Disclosed herein is actuation apparatus. The actuation apparatus comprises a diaphragm valve, having an upstream side and a downstream side, opposite the upstream side. The actuation apparatus also comprises a hydraulic actuator, fluidically coupled with the downstream side of the diaphragm valve by a first hydraulic line. The actuation apparatus further comprises a valve fluidically coupled with the upstream side of the diaphragm valve by a second hydraulic line. The actuation apparatus additionally comprises a valve controller coupled with the valve and operable to open and close the valve. Pressurized fluid from the downstream side of the diaphragm valve flows to the hydraulic actuator, via the first hydraulic line, in response to opening of the valve. The hydraulic actuator is configured to actuate in response to receipt of pressurized fluid from the downstream side of the diaphragm valve.

The bowl portion of the flush toilet includes a bowl-shaped waste receiving surface and a rim portion formed on a top edge of the bowl portion. The rim portion includes a rim inside wall portion located on an inner side of the top edge of the bowl portion. The rim inside wall portion has a rim inside surface located at a lower area of the rim inside wall portion and a rim inside wall upper sloped surface having a section in a vertical plane, the shape of the section being sloped from an upper edge of the rim inside surface to an upper edge of the rim inside wall portion. The ratio between the height of the rim inside surface and the height of the rim inside wall upper sloped surface is 1:1 to 6:1 in a section in a vertical plane at any area other than a rear area.

A tankless toilet system includes a tankless toilet and a sensor. The tankless toilet is configured to receive water from a water source. The tankless toilet includes a bowl, a first supply conduit, a rim jet, a sump, a second supply conduit, and a sump. The first supply conduit is configured to receive the water from the water source. The rim jet is fluidly coupled to the first supply conduit and configured to provide the water to the bowl. The sump is configured to receive the water from the bowl. The second supply conduit is configured to receive the water from the water source separate from the first supply conduit. The sump jet is fluidly coupled to the second supply conduit and configured to provide the water to the sump. The sensor is coupled to the tankless toilet.

A toilet includes a bowl with a sump and a trapway connecting the sump to an outlet of the toilet. The trapway has a zeta shape and is configured to induce a siphon which provides pressure to suction waste water from the bowl during a flush cycle. A trapway supply conduit is connected to the trapway in a tangential orientation to an upleg region of the trapway. The trapway supply conduit supplies water to the trapway, which follows a contour of the inner surface of the trapway supply conduit and continues in the same direction into the upleg region of the trapway by relying on a fluid flow to follow the curve of a convex surface placed proximate to the flow.

A system for monitoring flush valves is provided, including a plurality of flush valves arranged in at least one restroom of a building, each flush valve of the plurality of flush valves including a communication device configured to transmit flush valve data, and at least one controller in communication with each flush valve of the plurality of flush valves. The at least one controller is programmed or configured to receive the flush valve data from each flush valve of the plurality of flush valves and determine if a first flush valve of the plurality of flush valves is in need of servicing or replacement based at least partially by comparing flush valve data for the first flush with flush valve data for at least one other flush valve of the plurality of flush valves. A method and apparatus are also disclosed.

A system for adjusting a timing of at least one flush valve based on demand is provided. The system includes a plurality of flush valves arranged in at least one restroom. The system also includes a network device configured to receive wireless signals, and at least one processor in communication with the network device and the plurality of flush valves, the at least one processor programmed or configured to: detect, based on wireless signals received by the network device, a number of mobile devices in the area; determine whether the number of mobile devices in the area meets or exceeds at least one predetermined threshold; and in response to determining that the number of mobile devices in the area meets or exceeds the at least one predetermined threshold, adjusting the flush time of each of the plurality of flush valves to an adjusted flush time.
