A toilet fill valve is designed to maintain the proper water level in your toilet tank. A faulty valve could cause the toilet to overflow. You can simply and easily repair a faulty toilet fill valve by yourself.

Step 1 - Prepare for the Valve Repair

Turn the valve under your toilet tank in a counter-clockwise direction. This will turn off the water supply to your toilet. Remove the tank lid and place it in a safe place to protect it from any accidental damage. Flush your toilet to remove the water from the tank. Use a sponge or towel to soak up any moisture left in the toilet bowl.

Step 2 - Remove the Valve

Use your pliers to loosen the nut under the tank. Remove the nut, washer and lock nut. Raise the pipeline from the overflow tube. Remove the fill valve. The valve is connected to a rubber ball float.

Step 3 - Replace the Valve

Position the new valve in place of the faulty one. Tightly secure the lock nut, washer, and nut. Position the pipeline into the overflow tube.

Step 4 - Finish the Repair

Turn the valve under your tank in a clockwise direction in order to reconnect the water supply. Carefully position the lid on top of the tank.
