Repair worn-out fill valves to keep your toilet running smoothly and quietly
The fill valve is the part of the toilet that is responsible for refilling the tank after each flush. Over time, a fill valve may become worn, or out of alignment due to wear on the valve's components.
If your fill valve leaks, or if water continues to run after you flush, it may be time to replace the fill valve.
This guide will show how to make this quick and inexpensive adjustment to your toilet.

WHAT YOU NEED FOR THIS PROJECT
• Turn off the water at the shutoff valve and drain the tank by flushing the toilet.
• Place a small basin below the toilet tank to catch any excess water left in the tank, and soak up any remaining water in the tank with a sponge.
• Disconnect the old supply line.
Remove the fill valve nut, and then remove the fill valve.
Adjust the height of the valve so the marking on top of the valve is at least 1 inch above the overflow tube.
• Place the valve shank onto the fill valve, then insert the fill valve into the tank opening.
• Push down on the valve shank, and tighten the locknut one-half turn beyond hand tight.
• Connect the supply line.
Inside the tank, attach the refill tube (trim if necessary to avoid any kinks) and angle adaptor to the overflow.
• Turn the water back on.
• Allow the tank to fill.
• Adjust the water level by squeezing the adjustment clip and moving the float up or down. On some models the float is adjusted using a threaded screw sitting next to the float.
