Water is the essential element for our survival. The freezing point of water is 0°C. When the temperature reaches this particular point, water will turn into ice. However, there are many regions where the temperature falls to minus or below 0°C. For such places, it is hard to keep water flowing through pipelines.

To deal with this issue, we use frostproof yard hydrants. They save water from freezing and help us access smooth flowing without much fuss. Let’s check what a frostproof yard hydrant is.

What is a Frost Proof Yard Hydrant? 

A frostproof yard hydrant is a plumbing product that drains water from the ground without letting it freeze. It is also called a water pump, as it pumps water from the bottom to the top. These hydrants provide us with non-frozen water throughout the year.

The yard hydrant has an easy-to-understand structure. The head of the hydrant is on the top. It has a handle alongside. The handle has to be lifted when you want to start the flow. Now, the hydrant is operational. Similarly, we need to pull down the handle to stop the flow.

The first proof yard hydrant had a considerable length buried in the ground. It is that point from where water is drained under the frost line. Yard hydrants are generally installed in open areas. Their applications are houses, farms, gardens, etc. They can also serve the purpose of delivering potable water and other uses.

Parts Of Frost Proof Yard Hydrant.

Yard hydrants are very durable in their performance. But sometimes, a problem may occur in one of the parts of the yard hydrant. In such a situation, we can replace the damaged part instead of changing the hard hydrant. It will be more convenient and budget-friendly.

Before looking for a part of frost proof yard hydrant, you must know its details. Below are the parts of the yard hydrant and their essential features.

  1. Head of the hydrant: The head of the frostproof yard hydrant is the most prominent and essential part. The head comes in varieties, but they all share the same purpose. The handle on the head is responsible for lifting the pipe or rod. It allows water to circulate through the vertical pipe to the head.

The hydrant head comes with the feature of adjustments. Its packing contains a nut. If the rod is misplaced, we can fix it with the help of a nut. The nut can also save the day by treating the problems like leaking, seeping, etc. Flow control is another option. Using this feature, you can adjust the water flow per your needs. This property is imposing when you aim for a specific flow limit.

The head of the hydrant also has an outlet opening sometimes. It can be connected to some pipelines. This feature is excellent for connecting directly with the hydrant on farms, gardens, or for household purposes.

  • Straight Pipe: A vertical pipe starts from the bottom of the head and reaches down into the ground. Usually, galvanized pipes are good to go, and they are commonly used. Yet, if the water content or soil is corrosive, it is better to get a stainless steel or brass pipe. The length of the pipe varies. It can be somewhere between 1 and 8 feet. It remains empty when the water supply is shut off.
  • O-Rings: O-Rings are valve assemblies used in frost Proof Yard Hydrants. Observations show that using an o-ring setup gives a good-quality flow. Two or more O-rings arranged in a sequence can cut off the water supply. But O-rings have one serious disadvantage. They can wear out very fast and need regular maintenance. In such cases, alternatives are also present.
  • Rubber Plungers: Rubber plunger is a good option when O-rings are not performing well. Plungers last for longer without getting damaged. They don’t need to be replaced soon. Yet, plungers come with a steel rod that can be affected by corrosion.

How to Install Frost Proof Yard Hydrant?

Installing a frostproof yard hydrant is more challenging than simply installing a plumbing fitting. If you do it for the first time, you must dig a lot of soil. Also, the hydrant has to be connected to the water source. If no supply line is available, we must create a new line towards the hydrant. You can do it on your own or can call a plumber.

Let’s check how to do the installation.

Required Tools: 

  • Pipe Cutter.
  • Shovel.
  • Pliers.
  • Level.

Required Material: 

  • Frost Proof Yard Hydrant.
  • Male Threaded Adapter.
  • 90° Elbow.
  • PVC pipe, tee fitting, and solvent Glue.
  • Plumber’s tape.
  • 1/2 inch Gravel.


(1) Digging the Hydrant location: Before starting the installation process, turn off the water supply. The very initial step is to dig soil at the point where we are going to install the frostproof yard hydrant near the underground supply. This supply should not be above the frost line. You can check the frost line if you at Google.

Installation requires enough digging, and we need to make a big hole. It should have enough depth that the hydrant pipe fits well. Be careful from damaging the underground water pipeline and use a shovel only.

  • Fix the Tee Fitting: We must install a tee fitting in the soil and the water supply line. Using the pipe cutter, take out a section of the water supply line at 90 degrees. At this point, we will attach the hydrant apparatus. It will connect the hydrant with the water supply, and we will get access to water. With the help of solvent glue, fix the short part of the PVC hydrant pipe with the supply line. Take the level from your tools and ensure the tee fitting and the supply line are perfectly aligned.
  • Attach the Adapter: We have attached a short pipe with the main underground supply. Now, it’s time to connect the Elbow to the pipe outlet. We have to fix the adapter here with the help of a plumber’s tape. Right, the adapter with the use of pliers to hold it right. One side of the adapter connects the Elbow, and the second one connects the PVC supply.
  • Installing the Frost Proof Yard Hydrant: Now fix all. The extra fittings are required by cutting the pipes and adjusting them. Make sure that all fittings are secure and they are well-settled. Use solvent glue on the hydrant fittings. Wait for the glue to dry.

It is essential to note that you should check the hydrant is working before filling the dig with soil. Turn the water supply on and check how it’s going. If everything is sorted, then you are good to go. You can install 1/2 inch gravel to level the drain pipe. Now, you can fill up the hole by putting the soil back. And you are done with the installation process.

How Does a Frost Proof Yard Hydrant Work?

A frostproof yard hydrant works the same way a water pump does. It has a head with a handle that goes down into the earth and connects with the main supply line. The handle controls the vertical pipe, reaching the rubber plunger at the bottom.

When we lift the handle upward, it raises the plunger in the bottom, causing water to come to the top. Water circulates the hydrant pipe and ultimately reaches the outlet at the top. Similarly, when we lower the hydrant handle, water goes down.

When the handle is lowered, the plunger is closed, and the water is not allowed to go upside down. In this case, water remains in the drain of gravel present near the drain valve. This gravel is installed along with the frostproof yard hydrant. Water remains in the surrounding soil and is hindered from going into the hydrant pipe. This working of the hydrant is responsible for saving water from freezing even in the coldest temperatures.

The most important fact to remember is that the hydrant pipe must lie below the frost line. It is the line after which the water begins to freeze underground. This line lies at different depths for different locations.
