Claim:
A method for providing an adjustable bowl fill water flow in a toilet fill valve, comprising the steps of: operatively coupling an integrally molded bowl fill outlet port to a water inlet of the toilet fill valve; radially extending the integrally molded bowl fill outlet port from a portion of a body of the toilet fill valve, the integrally molded bowl fill outlet port comprising an integrally molded portion of the body of the toilet fill valve; coupling an integrally molded bowl fill valve inlet port comprising an integrally molded portion of a bowl fill valve directly to the integrally molded bowl fill outlet port by establishing direct contact between the integrally molded bowl fill outlet port and the integrally molded bowl fill valve inlet port, the integrally molded bowl fill valve inlet port being compatible with the integrally molded bowl fill outlet port, the integrally molded bowl fill valve being configured to provide for the adjustable bowl fill water flow out a bowl fill valve outlet port of the integrally molded bowl fill valve for filling a toilet bowl during a flush cycle of a toilet; providing for a configuration of the coupling between the integrally molded bowl fill valve inlet port and the integrally molded bowl fill outlet port that withstands a repeated pressure head created at the integrally molded bowl fill valve inlet port during a life cycle of the toilet fill valve without separation; wherein the step of coupling of the integrally molded bowl fill valve inlet port of the bowl fill valve directly to the integrally molded bowl fill outlet port further comprises the steps of: mating at least one locking ear with a corresponding at least one locking groove, respectively, the at least one locking ear being situated in a locking position of the at least one locking groove, the locking groove comprising a J formation; and compressing a sealing ring between an end of the integrally molded bowl fill valve inlet port and a seat of the integrally molded bowl fill outlet port, wherein the compression of the sealing ring pushes the at least one locking ear into the locking position.
