Is a Buried Frost-Free Hydrant More Reliable Than Above Ground?

Reduced Exposure to Freezing Temperatures

Buried frost-free hydrants are encased in a frost-proof housing that prevents water from freezing inside the hydrant. This housing is typically 12-18 inches below grade, which is below the frost line in most areas. By burying the hydrant, you can ensure that the water inside remains unfrozen, even in extreme cold weather. In contrast, above-ground hydrants are exposed to the full force of freezing temperatures, which can cause the water inside to expand and damage the hydrant.

Resistance to Damage from Snowplows and Other External Factors

Above-ground hydrants are also more susceptible to damage from snowplows and other external factors. When a snowplow drives by, it can easily damage the hydrant, causing leaks or even breaking the pipe. Buried hydrants, on the other hand, are protected from these types of impacts. Additionally, buried hydrants are also less likely to be struck by lawn mowers, ATVs, or other recreational vehicles.

Maintenance and Inspection

Buried hydrants are also easier to maintain and inspect than above-ground hydrants. Since the hydrant is buried, it requires less frequent inspection and maintenance, as the risk of damage from weather and external factors is reduced. However, regular maintenance is still necessary to ensure that the hydrant remains functional and safe. It’s recommended to inspect the hydrant annually and perform any necessary repairs or replacements.
