Under the plastic cap on top is a valve that allows water in the outside pipe to drain when the faucet is turned off AND there's no hose attached. This keeps the water and pipes from freezing. If there is no cap on top, it is a conventional faucet that can freeze if the water is not drained out from inside the house.
Turn the water fully on, then fully off. Now, remove the cap. If an amount of water comes out more than just a tiny little spray, then it's frost free. If you just get a little spurt of pressure and a hose cap full of water, then it's not a frost free hose bibb.
A freeze-proof spigot, also called an antifreeze spigot, employs the same design but with one important difference. It's attached to a tube that can be up to 24 inches long, and the compression valve is at the supply end of the tube. A long rod connects the valve to the faucet handle.
On the other end of the supply pipe is the shut-off valve. Although all outdoor spigots have a shut-off valve that controls water flow, conventional spigots place this valve outside in the cold where it can stall or freeze. In contrast, frost-free spigots position the valve inside of the home where it remains warm.
A hose connected to an outside faucet is exposed to the elements. The water inside the hose can rapidly freeze when the temperature drops below 32 degrees. Burst outside spigots is a potentially expensive problem that is relatively easy to avoid.
There's one main reason to drip your outdoor faucets: running water is less likely to freeze than stagnant water. This simple act can also help release pressure inside the pipes if they start to freeze. Water expands when it freezes, and if the pressure builds enough, it can damage your pipe.
A freeze-proof faucet protects your outdoor spigot from freezing and bursting. The design slopes downward toward the spout to drain water. An interior shut-off valve also protects water from building up and freezing in the pipe. These faucets are also called frost-proof faucets, spigots, or hose bibs.
The Importance Of Winterizing Outdoor Faucets
A burst spigot can lead to water flowing against the side of the house or even making its way inside. Investing in foam covers or even fashioning DIY covers from items in your home can help protect your pipes during a cold snap.
For added protection and to completely winterize your outdoor faucet, place a cold-weather cover over the faucet and secure the hook or drawstring (depending on what type of cover you purchase). Make sure the spigot is completely covered. For added protection, ensure the cover is tightened securely.
Hose bibs are designed for attaching garden hoses and have threaded spouts, while spigots are general-purpose outdoor faucets that may or may not be threaded for hose attachment.
A leaking frost-proof faucet can waste a lot of water, but fixes are simple, whether the problem is the faucet stem washer assembly, the vacuum breaker, or just a loose retaining nut. Start with the retaining nut, then look for other problems. Tighten retaining nut.
This means that when new homes are built, hose bibs and outdoor faucets must have an anti-siphon valve to pass most local plumbing codes. That being said, hose bibs don't last forever and are prone to damage, just like other fixtures in your home.
Frost-free hose bibs have a longer stem, extending into the interior of the home where temperatures remain warm enough to prevent the water inside from freezing.
Exterior pipes should be wrapped with insulation tubing, which can be found at your local hardware store. Do not wrap your pipes with bath towels or newspaper! These coverings hold moisture like a wet rag and defeat the purpose of covering your pipes in the first place.
Winterizing your outdoor faucet, also known as a hose bib or water spigot, is a simple project. If it's not done correctly, the consequences could be serious. A frozen outdoor faucet can cause serious water damage to your home and property.
One of the main functions of an outdoor faucet cover is to protect your pipes from freezing during the winter months. With winter temperatures that often dip into the teens, this is particularly useful in the Denver area. Faucet covers work by trapping heat that radiates from indoor plumbing to the outdoor spigot.
The product cannot freeze because there is no water in the faucet. When the valve is turned off, all of the water in front of the valve drains from the faucet leaving the tube empty.
Keeping your outdoor faucets protected means you'll be ready to leap into action when spring rolls around and it's time to turn on your sprinkler system again. You should winterize your pipes before temperatures regularly drop to 32 degrees Fahrenheit.
Freeze Miser protectors helped us do much during the last big freeze and kept our water troughs going for the cows. This customer chose to rate the product and not provide text. The freeze misers worked as advertised, keeping my outside hose bibs from freezing during extended temperatures well below freezing.
Typically, outdoor faucets should be opened when temperatures fall below 20 degrees Fahrenheit. Freezing water expands and can cause pipes to crack or burst. If you have a frost-free faucet, it provides extra protection, but you may still need to leave it open during extreme cold.
