A flushometer system includes a pressure vessel with a flow path defined between a valve inlet chamber and an outlet and a valve assembly disposed within the pressure vessel and configured to selectively open and close the flow path. A primary diaphragm assembly is disposed within the pressure vessel and includes a primary disc configured to be moveable to actuate the valve assembly to selectively open and close the flow path between the valve inlet chamber and the outlet, and a primary diaphragm connected to the primary disc. A secondary diaphragm assembly is disposed within the pressure vessel and includes a secondary diaphragm and a secondary disc, the secondary diaphragm assembly configured to actuate the primary diaphragm assembly by venting fluid pressure on one side of the primary diaphragm. An activation assembly is configured to actuate the secondary diaphragm assembly by venting fluid pressure on one side of the secondary diaphragm.

Provided are a flush water tank apparatus capable of restraining instability of an operation of a piston and restraining fluctuations in a water pressure of flush water discharged from a first discharge part provided separately from an inlet, and a flush toilet apparatus including the flush water tank apparatus. A discharge valve hydraulic drive portion of a flush water tank apparatus of the present invention includes a cylinder, a piston, and a rod extending from the piston through a through-hole portion formed in the cylinder, the cylinder including an inlet into which flush water flows, a first discharge part that is provided separately from the inlet to drain the flush water, and a second discharge part that is provided separately from the first discharge part and is formed between the rod and the through-hole portion and between the piston and the through-hole portion.

There are provided a flush water tank apparatus capable of reducing a pressure of flush water in a pressure chamber easily, and a flush toilet apparatus provided with the same. A discharge valve hydraulic drive portion of a flush water tank apparatus includes a cylinder in which supplied the flush water flows, a piston that is slidably disposed in the cylinder, partitions inside of the cylinder into a pressure chamber and a back pressure chamber, and further is moved from a first position to a second position by a pressure of the flush water that has flowed into the pressure chamber, an outflow portion from which the flush water in the cylinder flows out, and a communication mechanism that establishes communication between the pressure chamber and the outflow portion after the clutch mechanism is disengaged.

One example toilet has a porcelain body including a tank that defines a first fluid passageway, a bowl integral with the tank and connected with a second fluid passageway that intersects the first fluid passageway, the second fluid passageway is integral with the tank and the bowl, and an outlet located downstream of the intersection of the first fluid passageway and the second fluid passageway, and the outlet includes a seat. The toilet includes a flush mechanism inside the porcelain body and has a weighted stopper configured to contact the seat of the outlet, a flexible connecting element having a first end connected to the stopper, a float connected to a second end of the flexible connecting element, a pull chain having a first end connected to the float, and a rocker arm rotatably connected to the body and connected to a second end of the pull chain.
