Various methods and apparatus are described and shown (FIG. 1) utilizing several positions within the toilet fill valve (10) and the water supply conduit (180) for minimizing water from being wasted in toilets. Several embodiments (FIG. 1-4) are shown consisting of flow restrictors being tube restrictors (100a-d), base insert restrictors (130a-f) and connector restrictors (150a-b) that sufficiently slow the refilling of water within the toilet tank (70), thereby allowing the flapper valve (60) to close sooner rather than later. This action reduces the amount of water from being discharged into the sewer due to both the early and excessively fast refilling of water, and the unneeded water turbulence created by the toilet fill valve (10), thereby promoting water conservation and cost savings for the consumer.
