Winterizing Outdoor Faucets and Hose Bibs Before a Freeze in Central Oregon

This guide explains how outdoor faucets freeze, what to do before temperatures drop, and how to spot damage after a cold snap. It's written for homeowners and property managers in Bend, Redmond, Sisters, Sunriver, La Pine, Prineville and Madras, where overnight freezes are a normal part of the season. Most of it also applies to homes in the Portland metro area and Washington.

Why Hose Bibs Freeze First

An outdoor faucet — also called a hose bib, spigot or sillcock — sits on the exterior wall, exposed to the coldest air on the property. The pipe feeding it runs through an unheated section of wall or crawl space.

Water expands when it freezes. If water is trapped in that short run of pipe, the ice can split the pipe or crack the faucet body. The split often sits inside the wall where you can't see it.

Disconnect the Hose First

A garden hose left attached is the most common cause of freeze damage.

The hose holds water. That water freezes, backs pressure up into the faucet, and the faucet has nowhere to drain. Even a frost-free hose bib can't drain properly with a hose connected.

Before the first hard freeze:

• Disconnect every hose, splitter and timer.
• Drain the hoses and store them somewhere sheltered.
• Open the faucet briefly to let any remaining water run out, then close it.

Shut Off and Drain the Line

Many homes have an interior shut-off valve for each outdoor faucet. Look in the crawl space, basement, garage or utility room, on the pipe that heads toward the exterior wall.

If you have one:

1. Close the interior shut-off valve.
2. Open the outdoor faucet and leave it open so the line can drain.
3. If the shut-off has a small bleeder cap, open it to release trapped water.
4. Leave the outdoor faucet open through winter.

If you can't find a shut-off valve, the line may be a frost-free model or may not have one. A licensed plumber can identify what you have and add a shut-off if the plumbing allows.

Frost-Free Faucets Still Need Attention

A frost-free hose bib has a long stem that closes the valve well inside the heated wall, away from the cold. It's a real advantage, but it isn't automatic protection.

Two things matter:

• The hose must be disconnected, or the faucet can't drain.
• The faucet must be pitched slightly downward so water actually runs out.

A frost-free faucet that drips after you shut it off usually has a worn washer or a damaged stem. That's a repair worth making before winter, not after.

Insulating Exposed Plumbing

Foam faucet covers are inexpensive and help in mild freezes. They work best combined with a drained line, not instead of one.

Also worth checking:

• Pipe insulation on exposed lines in crawl spaces and garages.
• Open crawl space vents near plumbing runs.
• Unheated garages or outbuildings that contain water lines.
• Irrigation backflow devices above ground.

Vacation homes and rentals deserve extra care. A property that sits empty through a cold stretch has no one to notice a drip or a drop in pressure.

How to Tell If a Hose Bib Froze

Freeze damage doesn't always show up during the freeze. It often appears on the thaw, when ice melts and water starts moving through the split again.

Signs to watch for:

• You turn on the faucet in spring and little or no water comes out.
• Water sprays from the wall or from inside the house when the faucet is opened.
• A damp patch, stain or musty smell on the interior wall behind the faucet.
• Water in the crawl space or a spike in your water use.

If you suspect a split line, shut off the water supply to that faucet — or the main shut-off if you can't isolate it — before doing anything else.

When It Becomes an Emergency

A cracked hose bib can leak quietly for weeks or flood a crawl space in an afternoon, depending on where the break is. Treat it as urgent if water is running and you can't stop it, if you see water inside a wall, or if the crawl space is taking on water.

Emergency plumbing service is available throughout Central Oregon, Portland and Washington communities. In Bend, emergency plumbing is available 24/7. Other Central Oregon locations, including Sisters, La Pine and Madras, are served during business hours.

A Simple Fall Checklist

• Disconnect and drain all hoses.
• Close interior shut-off valves for outdoor faucets.
• Open the outdoor faucets and leave them open.
• Cover exposed faucets.
• Insulate exposed pipe in crawl spaces and garages.
• Repair any faucet that drips or won't fully close.
• Drain and shut down irrigation systems.

Related Winter Plumbing Checks

Freezing weather stresses more than the hose bib. While you're at it, note anything unusual: a water heater that's slow to recover, drains that are running sluggish, or water pressure that seems off. Small issues are easier to handle before a cold snap than during one.
