What Does a Toilet Fill Valve Do?
Some parts of your toilet like the toilet fill valve can be replaced as a DIY project. The fill valve is usually found on the left side of the tank and has a tailpiece that goes through the bottom of the tank.
Function of the Toilet Fill Valve
The fill valve opens and closes when you flush the toilet to allow for proper water flow in the tank. It goes through natural wear and tear, so having to replace the fill valve eventually isn’t unusual. If your fill valve is an older model that uses a float ball, you may want to take the chance to upgrade to a newer technology when it needs to be replaced. Fill valves with an integrated float cup are more dependable than those with a float ball.
Flush Valve Assembly
Some people choose to replace the entire flush valve assembly when the valve needs to be replaced. You don’t have to install a new assembly unless the assembly is also worn out. Installing a new assembly is a little more complicated than replacing the fill valve because you’ll need to remove the entire tank to do this.
Signs Your Toilet Fill Valve Needs to Be Replaced
If you constantly hear running water through the tank, your fill valve may need to be replaced. You can check by adding a few drops of food coloring to the tank. If no food coloring enters the bowl, then your fill valve is probably in need of replacement. You don’t want to ignore this problem because it increases your water consumption and reduces the effectiveness of the flush.
