Method and apparatus for reducing water consumption of a toilet

Abstract

An apparatus for reducing water consumption of a toilet having a toilet tank with a vertical standpipe through which fluids enter the toilet tank and a fluid escape opening through which fluids escape from the toilet tank. The apparatus includes a rigid liner body adapted for insertion into the toilet tank to reduce the capacity of the toilet tank while improving flow dynamics. The liner body has a bottom and four sidewalls. At least two of the sidewalls converge inwardly toward the bottom. The bottom has a drain passageway adapted to overlie the fluid escape opening in the toilet tank. One the converging sidewalls has a standpipe passageway adapted to accommodate the standpipe of the toilet tank.

1 . Method for reducing water consumption in a toilet having a toilet tank with a vertical standpipe through which fluids enter the toilet tank and a fluid escape opening through which fluids escape from the toilet tank, comprising the steps of:
 providing a toilet tank liner adapted to fit within the toilet tank, the liner having rigid body with a bottom and four sidewalls, at least two of the sidewalls converging inwardly toward the bottom, the bottom having a drain passageway adapted to overlie the fluid escape opening in the toilet tank, at least one of the sidewalls having a standpipe passageway adapted to accommodate the standpipe of the toilet tank;   inserting the liner into the toilet tank with the drain passageway axially aligned with the fluid escape opening and the standpipe extending up through the standpipe passageway, such that the converging of the at least two of the sidewalls reduces the amount of water held by the toilet tank and directs water toward the fluid escape opening when the toilet tank is flushed.   
   
   
       2 . An apparatus for reducing water consumption of a toilet having a toilet tank with a vertical standpipe through which fluids enter the toilet tank and a fluid escape opening through which fluids escape from the toilet tank, comprising:
 a rigid liner body adapted for insertion into the toilet tank to reduce the capacity of the toilet tank while improving flow dynamics, the liner body having a bottom and four sidewalls, at least two of the sidewalls converging inwardly toward the bottom, the bottom having a drain passageway adapted to overlie the fluid escape opening in the toilet tank, one of the at least two converging sidewalls having a standpipe passageway adapted to accommodate the standpipe of the toilet tank.   
   
   
       3 . The apparatus as defined in  claim 1 , wherein the standpipe passageway has a depending sleeve that terminates on the same plane as the bottom.
