A frost free spigot is an outdoor faucet with a long stem that puts the shutoff valve inside your home’s warm wall, not at the handle outside. When you turn it off, the water in the stem drains out. With no water left in the cold part of the pipe, there is nothing to freeze and crack.
Plenty of Triad homes still have the old style outdoor faucet, and they are one of the first things to burst in a hard freeze. Our outdoor spigot replacement service swaps them for frost free models across High Point, Greensboro, Winston-Salem and nearby towns. Call (336) 462-1080 any hour and a real person will pick up.
Key Takeaways
- The valve sits indoors. A long stem moves the seal 4 to 12 inches or more back into the heated side of the wall.
- It drains itself. A slight downward slope lets leftover water run out every time you shut it off.
- Hoses defeat it. A hose left attached traps water in the stem, and the spigot can still freeze and split.
- The Triad freezes every year. Greensboro’s average first freeze lands around November 1.
- Backflow protection matters. Most modern models include a vacuum breaker that keeps hose water out of your drinking water.
How Does a Frost Free Spigot Work?
A standard outdoor faucet closes right behind the handle, at the outside face of your wall. The water sitting in that short pipe is exposed to the cold. When it freezes, it expands and splits the faucet or the pipe behind it.
A frost free spigot moves that closing point inside. When you turn the handle, a long metal rod turns a washer that seals against a seat at the far end of the tube. The water stops where the house stays warm.
The tube is installed with a slight downward pitch toward the outside. Once the valve closes, the water left in the tube runs out of the spout. That is why you may see it dribble for a few seconds after you shut it off. That is normal, and it is the design doing its job.
The Main Parts
- Handle and spout. The part you see on the outside of the house.
- Long body tube. The pipe that runs back through the wall, usually 4 to 12 inches or longer.
- Stem and washer. The rod that runs the length of the tube and the rubber washer that seals at the inside end.
- Vacuum breaker. A small cap or valve near the handle that stops hose water from being pulled back into your pipes.
Why NC Homes Need a Frost Free Spigot
North Carolina winters are mild compared to the Midwest, which is exactly why so many homes get caught off guard. The cold comes in short, sharp snaps. One night in the teens is enough to split a standard faucet.
The NC State Climate Office lists Greensboro’s average first freeze as November 1, with the earliest on record on October 4. That means hoses and outdoor faucets can be at risk before many people even think about winter.
Local utilities say the same thing. Winston-Salem frozen pipe tips warn that pipes are more likely to be damaged by freezing once temperatures drop to 20 degrees or below. They also tell residents to disconnect and drain outdoor hoses and to cover outdoor faucets.
Crawl Spaces Make It Matter More
Many older homes in High Point, Greensboro and Winston-Salem sit on vented crawl spaces over red clay. The pipe feeding an outdoor faucet often runs through that crawl space, which can get very cold during a long freeze.
A frost free spigot works best when its valve end reaches past the rim joist into a protected area. In a cold crawl space, we also insulate the supply line leading to it. If you want the full list of steps for the rest of the house, see our guide to protecting pipes in winter.
Frost Free Spigot vs Standard Outdoor Faucet
Here is how the two compare in day-to-day use. Prices are typical national ranges for a professional replacement, and your exact price is always confirmed upfront.
| Feature | Standard outdoor faucet | Frost free spigot |
|---|---|---|
| Where the valve closes | At the handle, outside | Inside the wall, in the warm zone |
| Drains after shutoff | No | Yes, when installed with a slope |
| Winter prep | Shut off inside valve and drain the line | Remove the hose |
| Freeze risk | High in a hard freeze | Low when no hose is attached |
| Backflow protection | Often missing on older units | Built in on most current models |
| Typical national replacement range | $150 to $350 | $200 to $500 |

How Do I Know If I Have a Frost Free Spigot?
You can usually tell from the inside. Find where the outdoor faucet comes through the wall in your basement, crawl space or garage. On a frost free spigot, the pipe connects several inches back from the outside wall, and there is a long body tube passing through it.
Outside, frost free models often stick out a little further and the handle may sit at a right angle to the wall. A short faucet that connects right at the siding, with a shutoff valve just inside, is almost always a standard faucet.
Still not sure? Check the handle in winter. If the faucet has an inside shutoff that someone closes every fall, it is probably a standard faucet. A plumber can confirm it in a minute during any service visit, and tell you whether the stem is long enough for your wall.
Signs Your Frost Free Spigot Is Failing
A frost free spigot is tough, but the washer wears out and a freeze can still crack it if a hose was left on. Watch for these signs:
- Dripping from the spout long after the handle is closed
- Water on the inside wall, ceiling or crawl space floor when you turn it on
- Weak flow or no flow the first time you use it in spring
- Water spraying from the vacuum breaker cap near the handle
- A handle that spins freely or will not shut off
- A damp spot or stain on the siding below the spigot
Water inside the wall when the spigot runs is the classic sign of a split tube. The crack sits inside the house, so it only leaks while the water is on. If you have already had a freeze, our post on thawing frozen pipes safely explains what to do next.
How to Winterize a Frost Free Spigot
A frost free spigot needs far less winter prep than a standard faucet, but it still needs a little. Do these steps before the first freeze, which in the Triad can come in late October.
- Disconnect every hose. This is the most important step. Remove splitters, timers and quick-connect fittings too.
- Open and close the spigot. Let it run a few seconds, shut it off and watch it drain. A dribble that stops is a good sign.
- Check for drips. If it keeps dripping, the washer may need replacing before winter.
- Add an insulated cover. A foam faucet cover adds protection during deep cold snaps.
- Insulate the supply line. Wrap any exposed pipe leading to the spigot in a crawl space or unheated garage.
- Store your hoses. Drain them and keep them in a garage or shed so they are ready for spring.
Frost Free Spigot FAQs
Do frost free spigots work?
Yes, when they are installed with the right slope and used without a hose attached in winter. The valve closes inside the warm part of the wall and the tube drains itself, so there is no standing water outside to freeze. Most failures trace back to a hose left on overnight.
Do frost free faucets need to be winterized?
Only lightly. You do not need to shut off an inside valve and drain the line like a standard faucet. You do need to remove the hose, check that the spigot drains and stops dripping, and add an insulated cover if your faucet faces a cold, windy side of the house.
How much does a plumber charge to replace a frost free spigot?
Typical national ranges run about $200 to $500, including the new spigot and labor. A longer stem, a hard-to-reach crawl space or brick siding can raise the cost. All-Star Plumbing of the Triad quotes your price upfront, and there is no charge if you decline the quote.
Will wrapping a towel around an outdoor faucet keep it from freezing?
Not reliably. A towel can soak up moisture and freeze solid, and it adds little real insulation. A foam faucet cover works better. Neither one helps much if a hose is still attached, because trapped water in the hose and stem is what freezes and splits the pipe.
