Abstract
In various embodiments, a water inlet of a toilet fill valve receives water from a water supply. A tank water outlet of the toilet fill valve provides a first portion of the water to a toilet tank. A bowl fill outlet port of the toilet fill valve provides a second portion of the water to a bowl fill restriction that is in direct contact with an extended portion of the toilet fill valve. The bowl fill restriction restricts the flow of the second portion of the water. The bowl fill restriction provides the second portion of the water to a tube that is in direct contact with the bowl fill restriction. The tube provides the second portion of the water to a toilet tank overfill tube.
