Tighten it down so the rubber washer squishes out and forms a good seal. Next, while applying downward pressure to the fill valve, take the locknut and screw it to the bottom of the fill valve, where it exits the bottom of the tank. But if you have a shallow tank or a deep tank, you may need to adjust the height of the fill valve by loosening the lock ring and raising or lowering the fill valve. If you have a standard tank, the fill valve will probably come preset to the right height. Adjust the top of the fill valve to about 3 inches above the overflow pipe. Place the new fill valve in the toilet, making sure not to tighten it down yet. Slide this piece up over the bottom shank of the fill valve. You'll need the locknut and the shank washer that comes with the new fill valve and for some models, you’ll need to remove an inner piece of the washer with your utility knife. Next, you're going to prepare the fill valve for installation. Other supplies you will need include a small bucket, a sponge, a pair of pliers, a pencil, a screwdriver, a tape measure and possibly a utility knife. Check this first and pick up a flexible supply line so you have one on hand to make this repair. You may also need a new supply line (the tubing that runs from beneath your tank to your water supply) if yours is a solid, inflexible line. This will generally run you anywhere from $10-$20. Pick up a new fill valve at your local hardware store, making sure it’s the correct fit for your toilet. Fortunately, it’s a relatively easy fix that can be done with minimal expense and a few basic tools and supplies. If you look inside the tank of your toilet and see that the fill valve is leaking or spraying water from either the top, or leaking water from the bottom of the tank, chances are good it needs to be replaced before it wastes you any more water or causes any damage to your home. Sometimes, a running toilet is caused by a bad fill valve that needs to be replaced.
