         6 . The flush water unit according to  claim 1 , wherein the supply pipes are stacked together in one or more parts to form a joint inlet piece. 
     
     
         7 . The flush water unit according to  claim 1 , wherein the inlet piece is equipped with sealing sleeves for sealing off the supply pipes with respect to an interior walling of the installation recesses. 
     
     
         8 . The flush water unit according to  claim 1 , wherein the front ends of the supply pipes are formed at least by separate shorter or longer extensions. 
     
     
         9 . The flush water unit according to  claim 1 , wherein at least one of the supply pipes is provided with a flexible section for adapting the supply pipe to at least one of a curve of the bowl body and the bowl edge. 
     
     
         10 . The flush water unit according to  claim 1 , wherein the supply pipes have an associated water distributor that can be connected with a water supply. 
     
     
         11 . The flush water unit according to  claim 10 , wherein the water distributor comprises:
 an upstream connection to the connection with a water supply,   a branching section that is provided downstream of the connection for dividing the flow of water into several partial flows and downstream of the branching section it has, for each of the partial flows,   a deflection section for deflecting the partial flows from a vertical direction of flow in the installation position into a horizontal direction of flow.   
     
     
         12 . The flush water unit according to  claim 1 , wherein the supply pipes individual, or combined into an inlet piece can respectively be connected to a separate water distributor, which forms the connection to at least one of at least one flush water outlet of a flush water tank and a different water supply. 
     
     
         13 . The flush water unit according to  claim 10 , wherein at least one of the flush water tank and the water distributor can be mounted on a frame-like wall element.
