There is no yard hydrant on the market that will truly last forever. Over time these rods can fail due to corrosion. This style is generally equipped with a steel rod that goes down and attaches to the plunger. The styles that use the plunger are less likely to have the entire plunger piece stuck down at the bottom when trying to repair.

They sometimes end up stuck down in the valve body, making it impossible to install new ones. However, the O-rings wear out much faster than plungers and are harder to replace. The hydrant brands that use an O-ring style setup tend to have a little bit better flow through the hydrant.
The more common approach is to use a rubber plunger attached to a rod to plug off the incoming water.

Some manufacturers opt for a series of 2 or 3 O-rings that when seated into place will shut the water off. There are two basic styles of valves, O-rings and plungers. It’s usually not worth the extra cost to buy a specialty hydrant, unless you have corrosive water or soils. There are specialty hydrants that have pipes made from brass or stainless steel, however these will cost significantly more. This standpipe is most often made of galvanized steel. The vertical pipe coming up out of the ground and the cast piece that makes up the “head” of the hydrant, should stand empty when the water is turned off. If there is a small amount of leaking or dripping, you can often adjust the packing nut to alleviate that issue. Many have a packing nut that can be adjusted if the rod in the hydrant comes out of alignment. Once you have it adjusted, you can keep that as a preset on your hydrant. Some hydrants will have flow controls that can be set so you can find the ideal flow of water. The last thing that you will find on all hydrant heads is a way to make adjustments to the hydrant. This is something to look out for when selecting a hydrant for your home or farm. Some hydrants will have this outlet threaded so that a garden hose or other attachment can be hooked up others and some hydrant will have just a smooth outlet. The head also has an outlet for water to flow through. They have a handle that when pulled up, will lift either the rod or the wet pipe (depending on the style of hydrant) allowing water to flow through the valve, up the vertical pipe and out the hydrant head. The top casted piece of a yard hydrant can come in many shapes and sizes, yet all serve the same basic purpose. There are 3 major parts to all hydrants: Yard Hydrant Head Each hydrant brand has unique features and different appearances. The most common yard hydrant brands are Woodford, Merrill, and Simmons.
Above the valve piece, is the drain hole where the excess water drains out when the hydrant is not in use. Below it, the pressurized waterline is ready to dispense water when opened. This valve piece is where the water shuts off.

It may crack or burst if frozen causing an underground water leak, which is a massive headache to fix. The bottom valve assembly on a yard hydrant cannot withstand freezing temperatures. The frost line varies from 0 to 8′ depending on the maximum frost depth in the region. The water lines need to be buried deep enough to prevent them from freezing. Yard hydrants attach to a pressurized water line from either a private well or a public water supply. Proper installation is key to having a long-lasting hydrant that doesn’t cause problems. The greatest benefit of a yard hydrant is that it will drain itself when turned off, so the pipe won’t freeze during any harsh weather conditions. A yard hydrant is part of your plumbing that allows you to have water to an outdoor location. All of these refer to the same piece of plumbing. Yard hydrants have gone by many names: frost-free hydrants, freeze-free hydrants, yard hydrants, water hydrants, and outdoor hydrants.
