A float valve is a device or system for evacuating water from underground water tanks, including those found in typical residential flush toilets. The modern float valve was invented by Jose Antonio de Alzate, a Mexican priest and surgeon, who first described the device in 17 90 in the Gaceta de Literatura Méxicana. Another early user of the float valve was Fray Juan de San Miguel in 1849. He described how the valve can be set to open automatically if it detects a rise in water pressure.
Flush toilet float valves are used mainly to shut off the water supply to the toilet when the flow of water to the storage tank is lower than the water flowing out of the storage tank. Most of these valves are fixed to the wall. Sometimes a float valve is fixed above the storage tank, but this is seldom the case today. Modern float valves are usually installed on the floor near the floor drain or septic tank. However, some old houses have water tanks which are located above the main sewage pipe.
The purpose of a float valve is to close the system when the volume of water flowing out of the tank is higher than the volume that is stored within. Usually, there is a control switch or knob on the side of the tank. To allow the flow of water to continue, the float valves are opened. If the water flow stops, then the float valves are closed.
Apart from normal public toilets, low water level package is required in certain industries, including dry cleaning, printing, pharmaceutical, pulp and paper yards and swimming pools. In such applications, float valves are used. These valves control the flow of water into and out of the storage tanks. Normally the valves are open to allow water to flow freely through the pipes of the tank.
It is necessary to use float valve for high water tanks in order to avoid overflowing of water tanks. There are certain precautions to be followed while opening and closing the valve. A high water level may result in flooding. Therefore, it is important to prevent such situation by controlling the flow of water through the pipes.
Ball valve and screw valve are the two types of float valves available in the market. Ball valves are self-contained valves that can be operated using a screw thread. A small hole is provided in the middle of the ball for water supply. Water flows from the ball valve and the supply hole in the middle of the ball gets filled with water. On the other hand, screw valve works on the principle of an o-ring.
In some of the float valve models there is also a ballcock fitted at the high water mark.

The ball Cock is also known as high limit switch or warning bell. It is usually located within the premises of the boiler or any other point where water supply is not supplied continuously. Normally the ball cock stops the flow of water when the pressure falls below a pre-determined level. The main advantage of ball cock is that it provides instant indication of low water level. However, it is necessary to keep a check on the constant supply of water.
The main advantages of these valves are their efficiency and operational life. Normally float valve works smoothly for over twenty years. Most of them are equipped with electronic controls that help them to automatically maintain the right level of water pressure. Low water level can lead to various plumbing issues. Therefore, it is very important to have a float valve within the premises to minimize the chances of any leakages.
