A toilet bowl refill water adjuster, including: a frame; a refill tube inlet and a refill tube outlet in the frame; a pair of opposing grooves in the frame, the opposing grooves having a series of positioning detents therein; and a roller moveable along in the pair of opposing grooves, wherein the frame is dimensioned to receive a toilet bowl refill tube passing through the refill tube inlet and outlet in the frame such that movement of the roller along in the pair of opposing grooves causes the roller to move in a direction to pinch the toilet bowl refill tube and thereby restrict flow through the toilet bowl refill tube, and wherein there is a linear relationship between the position of the roller in the pair of grooves and the flow rate through the toilet bowl refill tube.
