Abstract

This invention relates generally to an apparatus and a method for plumbing installations and more particularly to a mechanism and use of a mechanism contained within the water tank of a household toilet which improves the water consumption efficiency of the toilet by minimizing the amount of water consumed when refilling the toilet reservoir and bowl. The mechanism can be a constriction or water limiting device, such as an adjustable valve, pinching, squeezing or similar device, positioned in line with a refill tube, and between the fill valve and the overflow tube. By adjusting the flow-rate or maximum volume of water that can pass through the refill tube, the refill time for the toilet bowl and water reservoir can be synchronized, causing the reduction or elimination of water-wasting during refilling time.
