The average weight of a fire hydrant typically ranges from about 149 to 500 pounds (68 to 227 kilograms). Modern fire hydrants tend to be lighter and more streamlined compared to older models, which could weigh up to 800 pounds. The weight varies depending on the hydrant’s size, type, and the materials used, commonly cast iron or brass, which are chosen for durability and the ability to withstand high water pressure
. For example, some manufacturers’ hydrants weigh:
- Mueller: 183 to 235 pounds
- AVK International: 82 pounds
- Lingjack Engineering: 92 pounds
- Jones Water Products: 149 pounds
Older fire hydrants from the early 20th century were significantly heavier, often 500 pounds or more, making modern hydrants easier to handle while still maintaining strength and functionality
. In summary, fire hydrants weigh between approximately 150 and 500 pounds on average today, with older models being heavier. Their substantial weight is due to the heavy-duty metals used and the need to withstand high-pressure water inside as well as outdoor environmental conditions
