Abstract: A simple yet inexpensive device is presented which is used to divide the water normally supplied to the spill tube and gooseneck reservoir of a commode. Dividing the water supplied to the spill tube and diverting a substantial portion of that water to a holding tank of a commode saves water that is normally unnecessarily fed directly down the drain in the refilling process. The device is a small plastic insert that has a generally rectangular main body. At one end of this main body is a horizontal inlet tube. At the bottom of the main body are a number of lower vertical outlet tubes. In order to evenly disperse the inlet water among the vertical outlet tubes, the upper mouth of the vertical outlet tubes is constricted by narrowing the diameter of the mouth with respect to the inner diameter of the inlet tube. Water is thus distributed evenly among the lower outlet tubes.
