How to Winterize an Outdoor Spigot (Frost-Free Faucets Explained)
Before the first hard freeze of the season, disconnect and drain any hose still attached to your outdoor spigot, then shut off and drain the spigot itself if it isn't a properly installed frost-free type. Skipping this is how a cheap, five-minute task turns into a burst pipe and a repair bill, because water left inside a spigot expands when it freezes with nowhere to go.
Here's the full process, and what's actually different if you have a frost-free faucet.
Why this matters: how a frozen spigot causes a burst pipe
Water is one of the few substances that expands when it freezes rather than contracts. If a hose or a section of pipe is completely full of standing water when a hard freeze hits, that expansion has nowhere to go and the pipe or fitting can crack. The crack often doesn't show itself until the ice thaws days or weeks later, at which point you find out about a burst pipe when water is already leaking, sometimes inside a wall.
The fix is simple and preventive: don't leave standing water sealed inside a spigot or a connected hose when temperatures are about to drop below freezing for good.
Step-by-step: winterizing a standard (non-frost-free) spigot
If your outdoor faucet is a standard type (not the long-stem frost-free style covered below), this is the process:
- Disconnect any hose. A hose left connected traps water against the spigot and prevents it from draining properly, defeating the point even if you shut off the interior valve.
- Locate the interior shut-off valve. This is usually on the interior wall directly behind or near the outside faucet, in a basement, crawlspace, or utility area.
- Turn the shut-off valve clockwise until it stops, cutting water supply to that spigot specifically without affecting the rest of the house's plumbing.
- Open the outside faucet by turning its handle counterclockwise, and let any remaining water in the line drain out completely.
- Leave the outside faucet open through the winter so any residual moisture has somewhere to expand if a small amount remains, rather than sealing it shut against a full pipe.
Our garden hose winterizing guide covers the hose side of this same seasonal task in full, draining, coiling, and storing the hose itself once it's disconnected here.
Do frost-free faucets need this too?
A properly installed frost-free faucet is built with a long stem that extends well back into the warmer interior of the wall, so the actual shut-off point sits inside the heated part of the house rather than out at the spigot itself. Water doesn't sit exposed to freezing temperatures the way it does in a standard spigot, which is the entire point of the design.
That doesn't mean it's completely maintenance-free, though. Two things still matter:
- Disconnect the hose anyway. A hose left attached to even a frost-free faucet can trap water at the outdoor end and defeat the design's purpose, since the water can't drain back if there's nowhere for it to go.
- "Properly installed" is doing real work in that sentence. If a frost-free faucet was installed at a slight upward or level angle instead of angled slightly downward, water can pool inside it instead of draining back into the wall, which reintroduces the freezing risk the design is supposed to prevent.
If you're not sure whether yours is angled correctly or genuinely frost-free versus a standard faucet that looks similar, treating it with the same disconnect-the-hose habit costs nothing and removes the most common point of failure either way.
Extra protection: insulated covers for hard freezes
In regions with genuinely hard, sustained freezes, an inexpensive insulated faucet cover adds a layer of protection over either type of faucet. These slip over the spigot and secure with a drawstring or hook, trapping a pocket of warmer air around the fixture. It's a low-cost, low-effort add-on, not a substitute for disconnecting the hose and draining a standard spigot, but a reasonable extra step where winters are severe enough that even a well-installed frost-free faucet benefits from the added buffer.
Timing: when to do this each year
Do this before the first hard freeze, not generically "in winter." The damage that matters happens the first night temperatures drop hard enough to freeze standing water, and by the time you notice a leak from a cracked fitting, that freeze has already happened. Checking your local overnight forecast in fall and getting to this task a few days ahead of the first real cold snap is a safer habit than waiting for a specific calendar date.
This is also a good moment to double check the hose itself is put away properly, not just the spigot it connects to. Our how to choose a garden hose buying guide covers material trade-offs if the cold has been hard on your current hose year after year and it's time to consider a replacement.
What to do if you missed it and a freeze already hit
If the season's first hard freeze caught you before you got to this task, don't panic, but do check carefully before using the spigot again. Look for any sign of a crack, a bulge, or water pooling around the fixture or the wall behind it the first time temperatures rise enough to thaw. If everything looks normal and the spigot operates as expected with no leak, you likely got lucky, either the spigot wasn't full of standing water or the freeze wasn't severe enough to cause damage. If you notice a leak, dampness on an interior wall near where the spigot sits, or the spigot behaves differently than before (weak flow, won't fully shut off), treat that as a sign of a cracked component. Our outdoor spigot won't shut off or is leaking guide covers that repair, though a freeze-cracked fitting is more often a replacement than the standard washer fix that guide covers for ordinary wear.
Either way, get caught up on the process above as soon as you notice the miss, rather than waiting for the next reminder, since every additional freeze-thaw cycle on already-stressed plumbing raises the odds of a crack that hasn't shown itself yet.
FAQ
Do I need to winterize a frost-free faucet the same way as a standard one?
Not the full shut-off-valve process, since the design moves the shut-off point inside the wall. Still disconnect any hose, since a hose left attached can trap water at the outdoor end regardless of faucet type.
What happens if I forget to winterize my spigot?
If standing water freezes inside the fixture or the pipe behind it, the expansion can crack the pipe or fitting, often revealed only when it thaws and leaks, sometimes inside a wall.
Is an insulated faucet cover enough on its own?
For a standard (non-frost-free) faucet, no, it's an extra layer of protection, not a substitute for shutting off and draining the line. For a frost-free faucet in a hard-freeze climate, it's a reasonable added precaution.
How do I know if my faucet is frost-free?
Frost-free (or "freeze-proof") faucets typically have a noticeably longer body than a standard spigot, since the shut-off valve sits further back inside the stem. If you're unsure, treating it with the same hose-disconnect habit is a safe default either way.
When exactly should I do this each year?
Before the first hard, sustained freeze in your area, not on a fixed calendar date. Checking the forecast a few days ahead of the season's first real cold snap is a better guide than a specific date.
