       1. A dual flush flapper valve apparatus comprising; a lower hollow segment having an upper open top and an open bottom, said open bottom adapted to seal a valve seat of a known toilet discharge tube, an upper segment engaged with said open top of said lower segment, a clamp on pivot bracket adapted to receive and be clamped onto a standpipe of a known toilet discharge outlet, said upper segment being pivotally attached to said bracket to allow swinging movement of said upper and lower segments between a sealing and a non-sealing disposition with respect to said toilet discharge tube, said upper segment having an open top forming a valve seat adapted to receive a conventional flapper valve in sealing engagement therewith, an adjustable float cantilevered to said bracket on a side opposite to said upper and lower segments, said adjustable float comprising a lower portion adjustably attached to an upper portion, said bracket having pivot points thereon to accept pivot arms of a conventional flapper valve. 
     
     
       2. A dual flush toilet flapper valve as in  claim 1 , having a pocket into which can be placed weights to help hold the flapper valve segments on the toilet discharge tube. 
     
     
       3. A dual flush flapper valve apparatus comprising:
 a riser segment comprising a lower hollow segment having an upper open top and an open bottom, said open bottom adapted to seal a valve seat of a known toilet discharge tube and an upper segment engaged with said open top of said lower segment, said upper segment having an open top forming a valve seat adapted to receive a conventional flapper valve in sealing engagement therewith,   a clamp on pivot bracket adapted to receive and be clamped unto a standpipe of a known toilet discharge outlet, said upper segment being pivotally attached to said bracket to allow swinging movement of said upper and lower segments between a sealing and-non-sealing disposition with respect to said toilet discharge tube, said bracket having pivot points to accept pivot arms of said conventional flapper valve, and   an adjustable float cantilevered to said bracket on a side opposite to said upper and lower segments, said adjustable float comprising a lower portion adjustably attached to an upper portion.   
     
     
       4. A dual flush toilet flapper valve as in claim 3, having a pocket into which can be placed weights to help hold the flapper valve segments on the toilet discharge tube. 
     
     
       5. A dual flush toilet discharge valve apparatus as in claim 3, having an adjustable float cantilevered to said bracket on a side opposite to said riser segment, said adjustable float comprising a lower portion adjustably attached to an upper portion.
