What are the four types of fire hydrants?

    Fire hydrants are essential for controlling and extinguishing fires. They provide a ready source of water for firefighting and are often integrated into municipal water supply systems. There are four main types of fire hydrants: wet barrel, dry barrel, post indicator valve, and flush hydrants.
    Wet barrel fire hydrants are the most common type. They are called "wet" because water is always present in the main valve. They are used in areas where the temperature does not freeze the water in the hydrants. Wet barrel hydrants come in various sizes and are designed to meet different types of conditions.
    The dry barrel fire hydrant is a variation of the wet barrel. Dry barrel hydrants are used in areas where water may freeze during winter. Unlike wet barrel hydrants, they are drainable to prevent freezing, and no water is kept in the main valve.
    Post indicator valve fire hydrants are a specialized type of hydrant that is used in large piping systems, such as those serving high-rise buildings or underground fire mains. They have a "post" attached to the top of the hydrant, which shows whether the valve is open or closed.
     Flush hydrants are typically installed in areas with high pedestrian traffic, such as sidewalks or parking lots. They are flush with the ground and only rise when needed for firefighting.
