How Much Does A Fire Hydrant Weigh? (Answered!)

How Much Does Fire Hydrant Weigh?

Not just anybody can lift a fire hydrant. In most cases, the installation companies are responsible for moving the fire hydrants with their facilities, which is why it’s no surprise that most people don’t know how much they weigh. This post will tell you all you need to know about fire hydrant weights. Let’s dive into the answer to this burning question: how much does a fire hydrant weigh?

Fire hydrants come in all shapes, sizes, and weights. The average fire hydrant weighs anywhere from 300-500 pounds. However, some can tip the scales at 700 pounds or more.

You may have noticed the fire hydrants in your neighborhood during the summer when they’re out in full force. They are essential to a city’s infrastructure, and their weight can range from 300 to 500 pounds.

This weight can depend on things like where it’s located. For example, if you have one on an incline or corner lot that requires extra support during installation, your hydrant will weigh more than one without these considerations.

The weight of a fire hydrant also depends on its size and features and the materials used to make it. Another factor that affects its weight is the diameter of the pipe and the length of the pipe. For example, a 2-inch (50 millimeters) diameter cast iron or steel pipe weighs about 46 pounds per foot (or 4.5 kilograms per meter).

The size of a fire hydrant valve can also affect its weight. The larger valves are heavier than smaller ones; for example, an 8-inch (200 millimeters) valve weighs 880 pounds (400 kilograms).

Are Fire Hydrants Made Of Cast Iron?

Cast iron is a solid and durable material used for centuries. The first cast-iron fire hydrant was patented in 1801. Cast iron is made from iron ore and other minerals, heated to extreme temperatures until they crystallize and form a moldable solid. Fire hydrants need to withstand high temperatures, so it makes sense that the inventor chose this material.

The exact weight of a fire hydrant depends on the type of cast iron used to make it and the design. For example, some fire hydrants are made with stainless steel, so they won’t rust over time, adding up to 50 pounds or more to the weight.

What other materials are fire hydrants made of? Brass is a good example of one. It is suitable for fire hydrants as they are excellent for inlet connections that keep the inlet free of debris. Also, brass has high corrosion resistance so it won’t rust over time.

Why Are Fire Hydrants Heavy?

Fire hydrants are made from various materials, but cast iron is the most common. Cast iron is heavy and relatively inexpensive to produce, making it an ideal choice for our purposes.

  • The paint you see on fire hydrants also contributes to their weight. Fire hydrants are painted with special fire-resistant paints to protect them from corrosion over time. These paints add about 40 pounds per gallonβ€”and there’s quite a lot of paint on each hydrant.
  • The alloy that makes up your local fire hydrant can also be important in determining its weight (though not as much so as the paint). The alloys used may be made up of anything between 94% and 97% aluminum combined with other elements such as copper or zinc that give it its unique properties such as strength.
  • The water inside a charged hose can also contribute to the overall weight of a fire hose. The amount of water in your hose can vary depending on how much pressure you have behind it, but generally speaking, a fully charged hose weighs anywhere from 75 pounds to 250 pounds.
  • Their weight is also because its production comes from iron, a weighty metal. It also weighs this much because it has to withstand the pressure from the water flowing through it.

How Much Does A Cast Iron Fire Hydrant Weigh?

The cast iron fire hydrant weighs somewhere around 150 pounds. This cast iron barrel is quite dense and takes a lot of force to move. It’s made out of iron and other metals, which are weighty materials. That is why the fire hydrant weighs so muchβ€”it can withstand all that pressure from the water flowing through it.

What Is The Average Height Of A Fire Hydrant?

The average height of a fire hydrant is between 3 and 5 feet, but it also depends on the water size and the ground height. The taller you build your hydrant, the more expensive it will be to install.

How Does A Fire Hydrant Work?

On the most basic level, fire hydrants work by connecting an outlet to a supply of water. When this connection is made, water flows from the supply through underground pipes and into a street hydrant. When firefighters need to draw water from the hydrant for fighting fires or other purposes, they can manipulate the hydrant’s valve to either open or close it.

How Much Does A Fire Hydrant Cost?

Digging up a fire hydrant can cost between $2,000 to $4,000. If you want to install a private fire hydrant at your property can cost from $3,000 to $5,000.

How Long Does It Take To Install A Fire Hydrant? Installing a fire hydrant can take anywhere from 4 to 6 hours. This time also depends on the location of your property and how much digging it requires.


When you need a fire hydrant in your yard, you want one that will last. So go ahead and get the heaviest one you can afford.

You can also install a private fire hydrant in your yard, but it will cost you more money. If you’re looking for a cheaper alternative, consider getting a small fire hydrant suitable for lawn watering. If you decide to install one on your property, talk with your city or county about the laws surrounding them first.
