The apparatus includes an assembly for facilitating displacement of water mixed with the excrement from a lavatory bowl to an outlet or drain pipe. The assembly includes a flush valve seat, a piston rod, and a piston. Together, the assembly may function as single piston enabled to displace the excrement mixed with water. A partial vacuum energy generated by the assembly is combined with fluid power of water, enabling displacement of a mix of the water and the excrement.</p> |
