How to Winterize Your Outdoor Faucets Before the First Freeze
Of all the pipes in your home, outdoor faucets take the most direct hit from cold weather. They're exposed to outdoor temperatures with nothing but a thin layer of metal between the water inside and the freezing air outside. Winterizing them takes about fifteen minutes and is one of the simplest ways to avoid a burst pipe you won't discover until spring.
What you'll need
- A foam faucet cover (sold at any hardware store for a few dollars)
- A way to locate your interior shutoff valve, if your home has one
- A bucket or small container, in case of drips while disconnecting hoses
Step 1: Disconnect every garden hose and shut off the interior valve
This is the step most people forget, and it's the most important one. A hose left attached to an outdoor faucet traps water in the faucet and the pipe behind it. That trapped water has nowhere to expand when it freezes, which is exactly how faucets crack. Disconnect every hose, drain any remaining water out of it, and store it somewhere it won't sit full of ice all winter.
Next, look for a dedicated shutoff valve inside the house for each outdoor faucet, usually in a basement or crawlspace near where the pipe exits to the outside. Many homes, especially in colder climates, have one. If yours does, shut that valve off before winter sets in. This cuts off the water supply to the outdoor pipe entirely, which is the most reliable way to prevent freeze damage.
Step 2: Drain the pipe and add a foam cover
After shutting off the interior valve, go back outside and open the faucet to let any remaining water drain out. Some setups include a small drain cap or bleeder valve near the interior shutoff specifically for this purpose. Leave the outdoor faucet open (not closed) for the winter so any residual water or trapped air has somewhere to go rather than being sealed inside a closed system.
Even with the interior valve shut off, a foam cover adds an extra layer of insulation against the cold, particularly helpful for the faucet body itself and for homes without an interior shutoff valve. These covers simply slip over the faucet and secure with a drawstring or velcro strap, and they're inexpensive enough that there's little reason to skip this step.
What if you don't have an interior shutoff valve?
Many older homes don't have a dedicated interior valve for each outdoor faucet, especially those built before frost-free faucets became standard. If that's your situation:
- A foam faucet cover becomes even more important as your primary line of defense
- Consider whether your outdoor faucets are "frost-free" style, which have a longer stem that places the actual shutoff point further inside the heated part of the house, reducing freeze risk
- If you've had freeze damage before and don't have a shutoff valve, it may be worth having one installed ahead of the next winter
A quick pre-winter checklist
- Disconnect and drain all garden hoses
- Shut off the interior valve feeding each outdoor faucet, if present
- Open the outdoor faucet and leave it open for winter
- Install a foam cover over each faucet
- Note any faucets without an interior shutoff for future improvement
When it's time for backup
If you discover a faucet is already leaking, cracked, or won't shut off properly as you're going through this process, that's a sign of existing damage that winterizing alone won't fix. ProFlow Plumbing can inspect your outdoor faucets, install shutoff valves where they're missing, and handle any repairs before the temperature drops.
