Outdoor faucets are easy to forget until something goes wrong. With months of freezing weather every year, a neglected hose bib is one of the most common causes of split pipes and water damage that people discover in spring. Here is how to keep outdoor faucets working through every season, and how to spot trouble before it gets expensive.
Why outdoor faucets need extra attention here
Hard freezes are a given every winter, and lows regularly reach the single digits. A standard outdoor faucet holds water in the pipe behind it after you close it. When that water freezes, it expands and can crack the faucet, split the pipe inside the wall or damage the connection. You usually don't find out until the faucet is turned on in spring and water runs into the basement.
Know which kind you have
Standard hose bibs are the older style. The valve sits right at the outside wall, so water stays close to the cold. They have the highest freeze risk.
Frost-free sillcocks have a long stem that puts the valve 6 to 12 inches inside the wall, where it stays warmer, and they drain when you shut them off, as long as they are installed with a slight slope toward the outside. Quarter-turn ball valve faucets shut off fast but still need winterizing unless they are frost-free models.
If your home still has standard hose bibs, switching to frost-free sillcocks, each with a shutoff valve inside the house, is one of the best small upgrades you can make.
Spring startup
Before the first use, look at the faucet body and spout for cracks from the winter. Open the inside shutoff, then turn the faucet on slowly and watch for leaks at the wall and in the basement where the pipe comes through. Check the packing nut behind the handle for drips, and make sure the vacuum breaker cap on top of the spout moves freely and isn't corroded.
Summer and fall use
Don't leave a hose attached to a frost-free faucet when you're not using it. A connected hose traps water in the stem and defeats the freeze protection, and it is easy to forget it is there in October. A slow drip at the handle usually means a worn washer or packing. Wet soil or water stains on the outside wall near the faucet can mean a slow leak behind the siding.
Fall winterizing
Before the first hard freeze, usually by mid-October, disconnect and drain every hose. Close the shutoff valve inside the house for each outdoor faucet. Open the outside faucet to drain what is left in the line and leave it open. Add an insulated cover if you like, but only after the line is shut off and drained.
While you're there, seal any gaps where the pipe goes through the wall or rim joist. Cold air coming through those gaps is what freezes the pipe on the inside.
Signs a faucet needs repair
Dripping from the spout when it is fully closed. Leaking around the handle while it runs. Weaker flow than last year. Rust, corrosion or mineral crust on the faucet. Water stains or white residue on the wall below it. A handle that turns but doesn't fully stop the water. Frost on the outside wall in cold weather, even with the faucet closed. Any of these means the faucet should be fixed or replaced before winter.
What you can do and what to leave to us
Replacing a washer, tightening a packing nut or putting on a cover are reasonable DIY jobs. Replacing a standard hose bib with a frost-free sillcock means cutting into the water line inside the wall. A faucet that leaks from the wall rather than the faucet itself may have a cracked pipe inside. A frost-free faucet that still freezes may be installed at the wrong pitch or have a damaged stem. And any hose bib without a shutoff inside the house should get one.

Frequently Asked Questions
What is the difference between a hose bib and a frost-free sillcock?
A standard hose bib has its valve at the outside wall, so water sits in the cold. A frost-free sillcock puts the valve 6 to 12 inches inside the wall and drains when closed, which makes it far less likely to freeze.
Can a frost-free faucet still freeze?
Yes, if a hose is left attached or the faucet was installed without a slight downward slope. Either one traps water in the stem.
When should I shut off my outdoor faucets for winter?
By mid-October in most years. Close the inside shutoff, open the outside faucet to drain it, and disconnect the hose.
Why is my outdoor faucet leaking from the wall?
A leak at the wall rather than the spout often means the pipe or faucet body cracked inside the wall, usually from a freeze. It needs a plumber before it soaks the wall or basement.
