 said small volume floater ( 10 ), formed like thin sectioned hollow body, is positioned inside the flush body ( 3 ) being pivotally connected to the floater holes ( 87 ) on the flush body ( 3 ) via its small volume floater pins ( 50 ) near the bottom of the floater ( 10 ); and said floater ( 10 ) is connected to the lowermost end of small volume adjustment rod ( 11 ) from its adjustment rod attachment hooks ( 58 ) which are in the form of protrusion mutually facing to each other, at the bottom of the adjustment rod attachment surface of small volume floater ( 57 );    and said floater ( 10 ) is closed at the top and open at the bottom, to provide air being captured inside the small volume floater inner space ( 56 ) as long as there is water in the reservoir, to provide the small volume floater contact surface ( 53 ) on the small volume floater ( 10 ) being leaned to the overflow tube ( 4 ), in order to have a proper engagement of the small volume floater hooks ( 55 ) and the surface below small volume hook ( 94 ) on the overflow tube ( 4 ) when the overflow tube ( 4 ) being lifted upward for partial flush and to provide overflow tube being stably suspended in the reservoir full of water, until the water level drops down to the bottom level of the small volume pool floater ( 12 ),    said small volume pool floater ( 12 ), formed like thin sectioned hollow body, is placed inside the flush body ( 3 ) being connected to the small volume adjustment rod ( 11 ) via its small volume pool floater threaded surface ( 77 ), and said floater ( 12 ), is closed at the bottom and open at the top, filled with full of water, providing an additional weight for movement of said rod ( 11 ) and the small volume floater ( 10 ) downward and disengagement of said floater ( 10 ) from the overflow tube ( 4 ) by rotating outwards by the weight of the overflow tube ( 4 ) together with the weight of the small volume pool floater ( 12 ) with full of water, after the water level drops down to the bottom level of the small volume pool floater ( 12 ), to move overflow tube downward to close the discharge pipe and to stop the partial flush.    
   
   
       2 . A dual flush system (A) according to  claim 1 , characterized in that small volume floater ( 10 ) is shaped as a half-cylinder and containing a hole shaped as a semicircle in the middle where the center of the hole is coincident with longitudinal axis of the cylinder; comprising two small volume floater pins ( 50 ) with circular sections, placed on mutually opposite sides, with their axes parallel to this surface and perpendicular to the longitudinal axis of the small volume floater ( 10 ), on the small volume floater middle section surface ( 51 ); the small volume floater inner bore surface ( 52 ) being in the shape of a semicircle, and the small volume floater contact surface ( 53 ), which makes an angle with the small volume floater inner bore surface ( 52 ), being placed where the small volume floater inner bore surface ( 52 ) intersects the small volume floater upper surface ( 54 ); the small volume floater hooks ( 55 ) extending perpendicularly outward from the small volume floater middle section surface ( 51 ); the small volume floater inner space ( 56 ) which is the interior part of the small volume floater ( 10 ); the adjustment rod attachment surface of small volume floater ( 57 ), shaped as a semicircle or semi-ellipse, which extends downward starting from the small volume floater upper surface ( 54 ), and having an opening towards the outside of small volume floater ( 10 ); adjustment rod attachment hooks of small volume floater ( 58 ) which are in the form of protrusion mutually facing to each other, at the bottom of the adjustment rod attachment surface of small volume floater ( 57 ).  
   
   
       3 . A dual flush system (A) according to  claim 1 , characterized in that on the uppermost side of the small volume adjustment rod ( 11 ), there exists the upper conical hook ( 61 ), which is narrow at the top and enlarging downwards; and the attachment surface for small volume floater ( 64 ) which is located where the adjustment screw ( 63 ) ends.  
   
   
       4 . A dual flush system (A) according to  claim 3 , characterized in that the small volume adjustment rod ( 11 ), inside the flush body ( 3 ), is leaned to the surface just below the adjustment rod attachment hole ( 86 ) via its bearing protrusion to flush body ( 62 ) when the reservoir is full of water; meanwhile, it positioned on the adjustment rod attachment surface of small volume floater ( 57 ) on the small volume floater ( 10 ) by means of its small volume floater attachment surface ( 64 ).
