About Toilet Fill Valves

Regular maintenance on your toilet is very important, as failure to do so could result in costly repairs. A fill valve is one of the many parts within your toilet that commonly needs replacing. Toilet manufacturers design their toilets in such a way that fill valves can be easily replaced without the need to replace the entire toilet tank.

What Is a Toilet Fill Valve?

The fill valve does precisely what its name implies: it fills the toilet with water. It uses a float system to indicate the levels of water. If the water level in the toilet drops below the full level, the fill valve opens, allowing more water to enter. It also regulates water flow by closing when there is sufficient water in the tank. Toilet fill valves are becoming more water-efficient in that they use the minimum amount of water to wash away the waste. They also allow for a half flush or a full flush, depending on your specific flushing needs.

The Evolution of Fill Valves

Like many other components, the toilet tank fill valve has evolved over time to become more efficient. The toilet fill valve is also known as the ballcock valve. It uses a float to fill the tank. When the fluid level drops below a certain point, the float also drops, opening the valve and allowing more water to enter the tank. When the float reaches the full line, the valve shuts, and no more water will enter the tank. Two different designs are most commonly used among fill valves: the side float and the concentric design. Currently, the concentric design is used most often. The side float uses a float that is located on the end of the lever to open and close the fill valve. The concentric float valve is a tower-like valve that contains a plastic float. The inside float is what controls the opening and closing of the valve. The concentric design is more efficient than the side float.

The side float and the concentric float valve design are more commonly used for residential applications. For commercial applications, there are the siphon valve and the pressure-assist valve. These valves create more pressure with smaller amounts of water, which makes them ideal for commercial applications.

When selecting a ballcock for your toilet, it is essential to choose a compatible part. Using the wrong type of toilet fill valve may prevent your toilet from working properly and can also cause damage.
