Outdoor Faucet Covers and Hose Care Before the First Freeze
Before the first hard freeze (overnight lows near 28°F or colder), disconnect every garden hose, drain it, shut off the indoor valve that feeds each outdoor faucet if you have one, open the faucet to drain it, and cap it with an insulated faucet cover. In cold zones that usually means mid to late October; in mid zones, November.
A hose left attached traps water in the faucet body. When that water freezes and expands, it can split the pipe inside the wall, and you may not find the leak until spring when you turn the water back on. Frost-free sillcocks are designed to drain themselves, but only when the hose is removed.
Why this small job matters
- Burst pipes are expensive. A split supply line inside a wall cavity can soak insulation and drywall before anyone notices.
- Hoses crack too. Water left in a vinyl or rubber hose freezes and weakens the walls and fittings.
- Covers add margin. An insulated cover traps a little house heat around the faucet during cold snaps.
- Spring startup is easier. Drained, coiled hoses stored indoors last several more seasons.

- Check the forecast; finish this before the first night forecast at 28°F or below.
- Disconnect hoses, splitters, timers, and quick connects from every outdoor faucet.
- Close the interior shutoff valve for each outdoor line if your house has one.
- Open the outdoor faucet and leave it open briefly so trapped water drains; then close it.
- Install an insulated faucet cover snugly against the siding.
- Drain hoses by walking them downhill, coil them, and store them in a shed or garage.
- Bring hose timers and battery water controllers indoors.

Do frost-free faucets need covers?
Frost-free sillcocks close the valve deep inside the warm part of the wall, so the exposed part drains when the hose is off. They usually survive without a cover, but a cover still helps on exposed north or west walls and during long subzero stretches. The key step is removing the hose; an attached hose prevents a frost-free faucet from draining and defeats the design.
What if you do not have an interior shutoff?
Many older homes have standard outdoor faucets with no separate interior valve. In that case a well-fitted insulated cover is your main protection. Some gardeners also leave a faucet slowly dripping during extreme cold snaps. If a faucet has frozen or cracked before, or you see water stains inside near the line, have a licensed plumber add a shutoff or replace it with a frost-free model before winter. Plumbing changes are a job for a professional unless you are experienced.
How to store hoses over winter
Drain each hose fully, then coil it loosely or wind it on a reel. Storing a hose in a heated garage or basement keeps it flexible. Store it off the floor on a wall hanger to avoid kinks and rodent chewing. If you water late plantings into November in mid zones, see our guide to soaker hoses and plan to drain them after each use once nights drop below freezing.
Rain barrels and irrigation lines
Rain barrels should be drained and disconnected from the downspout before freeze, or they can split. Drip lines and soaker hoses in beds should be blown out or drained per the manufacturer's directions. Our rain barrel guide covers winter shutdown, and in-ground sprinkler systems should be blown out by an irrigation contractor.

Zone and timing notes
Zones 3 and 4 should finish by mid October. Zone 5 should be done by late October. Zones 6 and 7 usually have until mid November, but watch for early cold snaps. In Zones 8 and 9, a cover is cheap insurance for the occasional hard freeze; keep one handy and install it when the forecast calls for the upper 20s. Zones 10 and 11 rarely need covers.
Bottom line
Disconnect, drain, and cover every outdoor faucet before the first night at 28°F or below. Store hoses indoors drained. It takes fifteen minutes and protects against the most avoidable plumbing repair a gardener can face.
