What are the four primary components of a fire hydrant?

The primary components of a fire hydrant include the inlet pipe, main valve, barrel, and head. The inlet pipe serves as the connection point between the hydrant and the water supply, allowing water to enter the hydrant system. The main valve controls the flow of water from the hydrant, enabling it to be opened or closed as needed. The barrel is the vertical portion of the hydrant where water is stored and it connects the main valve to the head. Finally, the head is the upper part of the hydrant that has one or more outlets where hoses can be connected.

Understanding these components is essential for maintenance and operation, ensuring that firefighters can quickly and effectively access water during emergencies.
