• Running toilet. A running toilet is one of the most common signs of a bad fill valve. This is because a bad fill valve can allow water to continuously flow into the toilet tank, even after the toilet has been flushed.
• Leaking toilet. A leaking toilet can also be a sign of a bad fill valve. This is because a bad fill valve can allow water to leak from the toilet tank into the bowl.

• Bubbling or gurgling noises from the toilet tank. If you hear bubbling or gurgling noises coming from your toilet tank, this could be a sign of a bad fill valve. This is because a bad fill valve can cause air to be trapped in the toilet tank, which can create these noises.

Step 4: Install the new fill valve.

To install the new fill valve, you will need to first apply a bead of plumber’s putty around the base of the valve. This will help to create a watertight seal. Once the putty is applied, you can insert the new fill valve into the tank and tighten the nuts that hold it in place.

Step 5: Turn on the water supply to the toilet.

Once the new fill valve is installed, you can turn on the water supply to the toilet. Flush the toilet to make sure that the fill valve is working properly.
