How to Winterize Outdoor Faucets and Prevent Frozen Pipes
Published September 12, 2026 · Updated September 23, 2026
An outdoor faucet sits right where a heated house meets winter air, which makes it one of the first places a hard freeze finds a way in. Water left in the pipe expands as it freezes and can split the pipe or valve, often inside a wall or crawl space. The damage usually shows up in spring, when you turn the water back on and it sprays where you can’t see it. Winterizing a hose bib takes about fifteen minutes and very little money.
Quick answer: Before the first hard freeze, disconnect and drain every garden hose. Close the indoor shutoff valve for each outdoor faucet, open the outdoor faucet to drain the line, and open the small bleeder cap on the shutoff valve if there is one. Leave the outdoor faucet open. Add an insulated faucet cover. Frost-free faucets don’t need an indoor shutoff but still need the hose removed.
Standard or Frost-Free?
| Standard hose bib | Frost-free sillcock | |
|---|---|---|
| Where the valve seals | At the outside faucet | Deep inside the wall, in heated space |
| How to spot it | Short body, handle close to the wall | Long body; the handle may sit farther out, and it often has a vacuum breaker cap |
| Winter prep | Indoor shutoff, drain, cover | Remove hose; cover optional |
| Common failure | Freezing between the shutoff and faucet | Freezing when a hose is left attached |
Frost-free faucets must slope slightly downward toward the outside so they drain. If yours has frozen before, check its slope and length, or have a plumber look at it.
What You’ll Need
- Insulated foam faucet covers (one per faucet)
- Flashlight for finding shutoff valves
- Small bucket and towel
- Optional: foam pipe insulation for exposed pipes in unheated spaces
Step 1: Disconnect Every Hose
Walk around the house and remove every hose, splitter and timer, including on garages and sheds. A connected hose traps water inside the faucet, even a frost-free one, and is the most common reason those faucets freeze. Drain hoses, coil them and store them in a garage or shed so they don’t crack.
Step 2: Close the Indoor Shutoff
Most homes in cold climates have a small valve on the pipe feeding each outdoor faucet, usually in the basement, crawl space or utility area near where the pipe exits the wall.
- Gate or globe valve (round handle): turn clockwise until it stops.
- Ball valve (lever handle): turn the lever perpendicular to the pipe.
Label the valves while you’re there to make next year faster.
Step 3: Drain the Line
- Open the outdoor faucet fully and let the water run out.
- Back inside, put a small bucket under the shutoff valve and loosen the bleeder cap (a small brass cap on the side of many valves) to release trapped water. Close it again once it stops dripping.
- Leave the outdoor faucet open all winter so any remaining water can expand or drain.
Step 4: Cover and Insulate
- Fit an insulated cover over each faucet and tighten the strap so it seals against the wall.
- Wrap exposed supply pipes in crawl spaces, garages or basements with foam pipe insulation.
- Seal gaps where pipes pass through exterior walls with caulk or expanding foam to keep cold air out. Our weatherstripping guide covers other drafts worth sealing.
Covers help a lot with short cold snaps but won’t protect a pipe that’s still full of water during a long, hard freeze.
If There’s No Indoor Shutoff
- Confirm whether the faucet is frost-free (long body) and remove the hose.
- Add an insulated cover.
- In a cold climate, consider having a plumber add a shutoff valve or replace a standard bib with a frost-free sillcock. It’s usually a modest job and prevents a much more expensive repair.
Other Outdoor Water Lines
- Sprinkler systems need their own winterizing; see our sprinkler guide.
- Pool and hot tub lines, outdoor showers and outdoor kitchens need draining per their manuals.
- Rain barrels should be emptied and disconnected so they don’t crack.
- Garage and crawl space pipes may need insulation or heat tape rated for the purpose.
Signs a Pipe Has Frozen
| Sign | What it suggests |
|---|---|
| No water or a trickle from a faucet on a cold day | Ice blockage in the line |
| Frost on an exposed pipe | Pipe at or near freezing |
| Bulging or split pipe | Burst pipe; leak when it thaws |
| Water stains or dampness near an exterior wall | Leak inside the wall |
| Wet spot or spray the first time you use the faucet in spring | Cracked pipe or faucet |
What to Do if a Pipe Freezes
- Close the shutoff for that line, or the main water valve if needed.
- Open the faucet so melting water and pressure can escape.
- Warm the pipe gently with a hair dryer on low, a heating pad or warm towels, starting near the faucet and working back toward the frozen section.
- Never use an open flame or a torch.
- Check for leaks once water flows again, inside and out, and watch the area for a few days.
If a Pipe Bursts
- Shut off the main water valve immediately. Everyone in the house should know where it is.
- Turn off electricity to affected areas if water is near outlets or appliances.
- Call a plumber and document the damage for insurance.
- Remove water and dry the area quickly to limit mold.

FAQ
When should I winterize outdoor faucets?
Before the first hard freeze in your area. Doing it as soon as you’re done with the garden in fall avoids being caught by an early cold snap.
Do frost-free faucets need winterizing?
They need the hose removed; otherwise water trapped in the hose can freeze back into the valve. A cover adds extra protection.
Should I leave the outdoor faucet open or closed?
Open, after closing the indoor shutoff and draining the line, so any remaining water can drain and expand safely.
Are insulated faucet covers enough on their own?
Not for a standard faucet with a full pipe during a long freeze. They’re a helpful extra layer, not a substitute for shutting off and draining the line.
