Let it flush out the valve for a few seconds! Drain the tank and start replacing — Turn off the water at the shutoff valve, and flush the toilet, holding the flush valve open to drain the tank and sponge out the remaining water. — Use a fill valve replacement toilet repair kit at your nearest hardware store and remove the coupling nut, old valve, and measure and cut the fill tube.
