What Is A Toilet Fill Valve?
A toilet fill valve is the part of the toilet located in the toilet tank that allows the water into the tank and controls the level of water that is allowed into the tank. This is important because it's the water that makes it possible to flush a modern day toilet.
Where is the toilet fill valve located?
The toilet fill valve is located in the toilet tank, usually on the left hand side, when facing the toilet. Although, some toilets have the fill valve located on the right side, of the toilet tank. The flushing mechanism, shown in this diagram, is a float ball type, which is no longer being installed in modern day toilets. This mechanism, can easily be replaced, with a modern day fill valve, that no longer has a ball and float arm.

Yes, toilet fill valves are like the tires on a car, there are many different sizes, with different tread pattern, but they all go on your car wheel and enable you to drive down the road. Toilet fill valves are interchangeable, they may have a different shape or be a different color, but for the most part will work just as well when it comes to filling your toilet tank with water. Just be sure to follow the manufacturer's installation instructions.
Will I Need To Remove The Toilet Tank To Install A New Fill Valve?
No, you simply have to turn off the water, to your toilet, and disconnect the water supply line from the tank. Remove the plastic nut from the bottom of the "Fill Valve" and disconnect the "Fill Tube" from the "Overflow Tube" and simply lift the valve out.
What Are The Signs That I Need To Replace My Toilet Fill Valve?
There are a number of indications that you might need a new fill valve, one would be if you have hard water and there is a build up of calcium in and around the valve. This will slow down the valve operation, taking a long time to fill, or can actually lock it in an open or closed position so that the valve operates continuously or barely works at all.
Then there is a situation where the seals inside the valve have become worn out or have a large build up of calcium, on them. This can cause the valve to spray water all over the inside of the tank, resulting in water leaking from the top of the tank and onto the bathroom floor. For the more advanced, do it yourself homeowners there is a kit available for replacing the seals in the fill valve, it cost about one third of a new fill valve and will often do the job. The kit is available from most home improvement stores.
What Is The Replacement Cost Of A New Toilet Fill Valve?
