Improvements in a tankless toilet flush system is disclosed. The Flush-All-Tankless device is disclosed in two versions: First version has the water output at the bottom that has an All-split-lock coupler joint assembly to connect it to urinals or some toilet bowls with no water tank mounting holes (like in many commercial toilet bowls). The second version has a factory built in All-Mounting-Base at the bottom to connect it to the remainder of toilet bowl systems on the market which includes all the toilet bowls with water tank mounting holes like in most residential toilet bowls. For those who prefer the porcelain look, an All porcelain cover can be used. This system eliminates the need for a water tank and can be used on toilet bowls with a wall mounted tanks used in many countries. This way the wall mounted tank can be completely eliminated.

The invention relates to a dual-discharge tank for toilets, including a tank, a water inlet having controlling means which are activated depending on the volume of water contained in the tank, a discharge mechanism coupled to a drainage collector, and means for actuating the discharge mechanism. The tank also includes an additional water inlet connected to a timed valve for controlling water flow, which automatically cuts off the flow of water through said inlet after a predetermined time has elapsed since the actuation thereof. The outlet of the timed valve for controlling water flow is connected to a first pipe that directs the additional water toward the drainage collector.

Embodiments of the invention provide a gasket for a fluidic seal. Some embodiments include a flush valve to a toilet tank, where the gasket has a raised center portion and lowered inner and outer portions. In some embodiments, the gasket includes a plurality of recesses, troughs or grooves. Each of the three portions of the gasket has a bottom groove that can permit deformation and increases sealing capabilities when the groove either widens or narrows. Additionally, some embodiments include an inner support ring that extends inwardly from the lowered inner portion, and can center the gasket onto the flush valve.

A flushometer valve assembly comprises a flushometer valve body including an outlet, an outlet tube including a conduit extending along a longitudinal axis, and a flushometer valve tube-to-body coupling that directly fastens the outlet tube to the flushometer valve body.

A flush actuator for engaging a flush valve. The flush actuator provides a mechanism assembly for automatically flushing the flush valve. A sensor provides a presence detection to trigger the automatic flushing. Redundant manual activation is provided.

The smaller volumes of water currently required to flush toilets and urinals may be insufficient to clear the fixtures and the drainage lines to which they are connected of waste and other undesirable materials, which can build up over a period of flushes or non-use. A flush valve control device programmed or otherwise configured to provide a selectable, periodic heavier flush volume of water after a predetermined number of low volume flushes and/or after a predetermined period of inactivity of the toilet or urinal can provide for sufficient drainage line carry-out of waste and prevent undesirable buildup of minerals, etc. on the inside surfaces of the fixtures and drainage pipes.

[Problem] To provide a flush valve capable of providing flush water at a high force.

[Means for solving the problem] A flush valve 1 connected on the downstream side to a toilet 2, comprising: a main valve unit 10 for causing a main valve body 11 to reciprocate between a closed position and an open position in response to pressure inside a back pressure chamber 27 communicating with a primary side flow path A, thereby opening and closing a flow path between the primary side flow path A and the secondary side flow path B; a sub-valve unit 30 having a sub-valve body 31 for opening and closing a bypass flow path 25 connecting the back pressure chamber 27 and the secondary side flow path B; and a generating unit 50, disposed on the downstream side of the main valve unit 10 and serving as a flow path resistance on the secondary side flow path B; wherein the bypass flow path 25 is connected to the secondary side flow path B downstream of the generating unit 50.
