A system that uses a flushometer for residential toilets in which adjustments and additions are made in order to allow the flushometer to operate correctly. There is an immediate flush water assembly that provides enough water, under pressure to pas through the flushometer. Also, a check valve can be used to isolate the pressurized water stored for the flush so as to reduce effect on the residential plumbing system and to provide control over flush and recharge. Also, a reduced diameter supply piping portion allows for additional control.

The present invention discloses a hydraulic energy storage mechanism, including a cylinder block, a cylinder body, a piston, a support, and a latch bolt component. In the present invention, a cylinder body, a piston, and a support structure being provided with a power slide block is used, and the tap water pressure is applied to push the piston to compress a spring and converted into elastic potential energy; the power slide block is driven by releasing the elastic potential energy to operate a suction drainage device of a water closet. The present invention has advantages of a small volume, large acting force, a simple structure, and reliable working, and effectively improves sewage drainage efficiency of the water closet.

A flushometer valve includes a hollow body and a piston assembly disposed inside the hollow body for controlling operation of the flushometer valve. The piston assembly and hollow body define an inlet chamber, an outlet chamber and a pressure chamber. The piston assembly includes a flow guide, a piston top, and an insert. The flow guide is movable relative to the hollow body between an open position, in which the outlet chamber is fluidly connected to the inlet chamber, and a closed position, in which the outlet chamber is fluidly disconnected from the inlet chamber. The piston top is coupled to the flow guide, includes a first material, and has a bleed passage that fluidly connects the pressure chamber and the inlet chamber. The insert is disposed within the bleed passage, includes a second material, and has a bore that fluidly connects the bleed passage and the pressure chamber.
