Frost Free Hydrants Buying Guide

Before you invest in a freeze-proof outdoor hydrant, you should consider the following factors so that you don’t regret your purchase later.

Bury depth of the hydrant

The bury depth is the depth of the hydrant that can be kept underground. It determines how far it can reach and connect with the main water source for stable water flow.

If you need water from deep down under, then choose a yard hydrant with a greater bury depth. Otherwise, a standard 2-feet bury depth can serve your purpose well.

It’s also important to know from beforehand whether you can install a hydrant with a longer bury depth. Always check the bottom of the hydrant to identify if it’s suitable for you and whether it is allowed to be installed.

Adjustable Water Flow Rate

Some hydrants come with a handwheel that can control the rate of the water flow. You might want to control this rate according to your needs.

For example, you don’t need a huge water force when you are gardening. But, you might want it for irrigating your farms and crops.

Hence, if you can adjust the water flow, you can save water and make optimum use of it. This type of customization may be desirable for you depending on your requirements.

Automatic Drain Out

An automatic drain out feature in a yard hydrant is essential if you are going to use it in freezing temperatures where you can’t afford to have the unit freeze up.

The auto drain feature drains out the water in the riser pipe after you have turned off the hydrant.

Hence, it ensures there is no water in the stand pipe that would be prone to freezing and damaging the whole unit.

Size Of Pipe Inlet

A small or large pipe inlet will determine how much water can be drawn from the main source pipe.

A large one is useful when you need a significant amount of water for irrigation purposes. Thus, a larger size pipe inlet will be better able to draw more water from the source.

On the other hand, if you need water for drinking from the hydrant, then a small pipe inlet will do the job.

Hence, the pipe inlet size is another consideration that can optimize water usage and prevent any waste.


If you want a durable outdoor hydrant, check out the material it is made of along with the material used for its components.

Solid brass, cast iron, and stainless steel are the preferred materials. Iron and brass bodies and heads can last a lifetime.

Stainless steel prevents the formation of rust and frost. The paint on the unit should be of high quality to protect it from the effects of the elements.

Anti-Theft System

If you live in an area where there can be water theft or unauthorized use, then a lock system can make sure the yard hydrant does not get misused.

Look for an auto-lock feature in the hydrant before you buy one. This will automatically lock the upper part after use and save water.

Where do I install a yard hydrant?

Check with your local utility office if there are any areas with water supply constraints. If none, you can install a yard hydrant anywhere as long as it’s not close to a well.

Keeping it away from a well prevents any accidental contamination of the water from the drainage port.

Yard Hydrant Installation Tips

Although installing a yard hydrant is not that complicated, you can still keep these tips in mind at the time of installation.

  • Ample Amount Of Gravel–Gravel saves the body of the hydrant from freezing by absorbing any excess water or any leakage. Lots of gravel ensure that there is proper drainage.
  • The Right Size Of Supply Pipe–To ensure that the flow and volume of water are working at an optimum level, always choose a water supply pipe that is one-inch thick.
  • Proper Drainage–Check if the drainage is working properly at the time of hydrant installation. Turn on the shutoff valve to allow the water to run. Turn it off and feel the hydrant head with your hand. You will know if there is suction, which indicates there is proper drainage.
  • Adjustments – At the time of installation, make sure the location you have chosen has been adjusted well to accommodate all the hardware related to the hydrant. Also, it’s important to check if the area has a steady supply of water.

What to do when A Frost Free Hydrant Freezes

A frost-free hydrant can freeze for a few reasons. If you haven’t used it properly, it can freeze up. The main water supply could have been at fault. Then there is the valve that can play foul if it hasn’t been adjusted properly.

Also, another reason is that if you keep getting water in a small amount from the hydrant, it may freeze up. Check the drain hole plugs and whether there is saturate draining in the gravel bed.

Even the best yard hydrant can freeze under these conditions. So, better safe than sorry.

How do I unfreeze a yard hydrant?

The first thing to do when you notice a frozen outdoor hydrant is to quickly try to thaw it to prevent any damage. You can do so by pouring hot water on the frozen area above the ground. Another tool you can use is a torch electric heat tape.

If there is freezing underground, you need to take out the head of the hydrant and pour boiling water down the riser pipe.

How does a yard hydrant work?

The working of a yard hydrant is pretty simple. You can either open it or close it.

The basic functioning is the same for all hydrants. You have a galvanized steel pipe with a shutoff valve that connects with the underground main water supply system.

The upper part of the hydrant has a head and a handle, while its lower part is buried underground. The middle part houses the riser or stand pipe.

A plunger controls the water flow up or down the riser pipe. The plunger and valve remain below the frost line.


When you lift the handle of the hydrant, the water flow will get into motion. The plunger and connecting rod will be raised from the valve seat when the handle is raised.

When the plunger is in a raised position, water flows through the valve and up the riser pipe and into the spout of the hydrant.

The drain port at the bottom is closed to enable water to flow up.


When you push down the handle, the plunger and connecting rod go back to the bottom of the valve seat. The plunger discontinues the water flow in the system and opens the drain port.

So, whatever water was left in the riser pipe, it is allowed to drain out through the drain port to prevent freeze-up of the hydrant. The drain bed absorbs this excess water.

What Do People Use Yard Hydrants For?

Yard hydrants are primarily used in three key places – farms, residences, and campgrounds.

As any farm is usually of a considerable area, it is hard to reach all the parts that require water – both livestock and crops.

If there is an outdoor hydrant, you can get water to these places and animals easily. Even with freezing temperatures, you can get fresh groundwater to where it’s needed.

In residences, you need a yard hydrant to wash your cars or pets. If such homes are in rural areas, a frost-free hydrant can supply water to other buildings on the land or livestock or crops.

Campgrounds that accommodate large groups of people need outdoor hydrants so that the campers don’t have to carry water from far places.

Therefore, time is saved and more people can be serviced within the same area of the campground.

Yard Hydrant Frequently Asked Questions (FAQ)

Does Water Taste Bad Due To The Use Of Hydrants?

The water may taste a bit of chlorine since this chemical is used as a disinfectant when flushing out the hydrants in your neighborhood. You will notice some discoloration due to the presence of sediments in the water.

Overall, water doesn’t taste bad when the hydrants are normally in place and not in the flushing season. It also depends on the taste of the water from the main supply. If it tastes fine, then the water from the hydrant will have the same taste.

Can Yard Hydrants Be Used For Hot Water?

Usually, yard hydrants are meant for handling either cold or normal temperature water. Hydrants that need to handle hot water need to have different specs. For example, they should be made of materials capable of withstanding high temperatures.

Moreover, steam and hot water minerals also become a consideration as to how a hydrant can be used for hot water.

Is The Attachment Like Sprinkler Or Hose Included With Yard Hydrants?

If you are buying a yard hydrant from one of the more renowned brands, then you will get the hose or sprinkler in the package. However, if you are looking at hydrants from lesser-known manufacturers, you may need to buy these attachments separately.

It’s recommended to invest in a good brand for long-term benefits that will be more economical.
