A pair of flexible or extensible panel members are adapted for vertical placement in the base of a conventional water closet flush tank in spaced relationship about the outlet valve such that edge portions of the panel members are in sealing contact with corresponding portions of the bottom and side walls of the tank, thereby forming an open-ended vertical column. During toilet bowl evacuation, savings of water normally consumed are realized as water stored in the tank and peripheral to the column is prevented from exiting the tank.

In a water closet having a flush tank formed by bottom and side walls and providing a hydraulic head and storage of predetermined height and capacity, having an outlet valve assembly mounted in the bottom wall of the tank and communicating with a toilet bowl, having manual handle means to open the valve to empty the tank and cooperative water supply means for refilling the tank upon the outlet valve returning to a closed position, the opening of the outlet valve normally causing initiation of the flushing and bowl evacuation followed by substantial emptying of the tank and subsequent closing of the outlet valve, the improvement comprising, in combination: At least one rectangular panel member adapted to be vertically positioned and fixably retained in spaced relation to the outlet valve whereby the panel member contacts opposite interior vertical wall surfaces of the said tank and a bottom horizontal edge of said panel member contacts the interior bottom wall surface of the tank to form in effect an open top column of less height than the normal water storage height and extending above and around the outlet valve assembly and closed at the bottom by the bottom wall of the tank and bounded at the side by said interior wall surfaces forming a continuation of the wall area of said panel member.
