Water diverter/saver for toilet tanks

In a flush closet including a toilet bowl and a toilet tank for supplying flush water to the bowl, water being supplied to the tank and bowl after each flush with a refill tube supplying the toilet bowl with water after a flush, the refill tube dispensing water into an overflow pipe in fluid communication with the bowl, the improvement comprising

• an adjustable diversion device which permits fresh fill water to the toilet bowl to be partially redirected to the tank from the refill tube, said diversion device consisting of:
• a diverter tube having a first end and a second end, a ribbed section formed on said first end for attaching to the refill tube,
• a first vent formed near said first end and opening onto said tank and a second vent formed near said second end and opening into said overflow pipe, each of said vents formed perpendicular to said diverter tube, said second vent having a rib formed parallel to and along said second vent,
• a clip formed perpendicular to said diverter tube and parallel to and in close association to said second vent for attaching the diverter tube to said overflow pipe, and
• an adjustment valve rotatably mounted in said second end, said valve extending into said diverter tube from said second end to a point forming a junction with said diverter tube at a point upstream of said second vent such that said valve can be rotated to open or close said second vent,
• whereby turning said valve adjustably controls the opening of said second vent, thereby reducing the flow of water through said second vent and increasing the flow of water through said first vent into the toilet tank.
