Abstract

A flush regulator for a toilet tank for regulating the outflow therefrom through an outlet, said regulator including a valve ( 107 ) without buoyancy, said valve adapted to close said outlet, a connector connected at one end to said valve and a body of buoyancy ( 109 ) at another end of said connector above said valve, said valve adapted to close said outlet when the water level in said tank reaches the upper edge of said body of buoyancy and said buoyancy and valve fall to close said outlet wherein said toilet tank includes an overflow pipe ( 101 ) wherein said body of buoyancy is connected to the overflow pipe by a plurality of attachment points and wherein the height of the body of buoyancy is varied by attaching the body of buoyancy using on e of the plurality of attachment points so as to adjust the height of the body of buoyancy relative to said valve.
