How Do I Keep My Pipes From Freezing in Flagstaff?
The best way to keep pipes from freezing is to protect the plumbing that's most exposed to cold: outdoor hose bibs, pipes in unheated spaces, and lines along exterior walls. Disconnect your hoses, insulate exposed pipes, and keep your home heated, even when you're away. Do it before the first hard freeze, not after.
When should I start protecting my pipes?
In Flagstaff, overnight freezes can start as early as late September or October. Pipes are at real risk once outdoor temperatures drop to around 20°F. Higher spots like Munds Park and Bellemont can get colder sooner.
Don't wait for a scary forecast. Handle the outdoor prep in early fall.
What should I do before it gets cold?
Start outside, then work your way in:
Disconnect garden hoses. A connected hose traps water in the hose bib and the pipe behind it.
Shut off and drain exterior lines if your home has an inside shutoff for them.
Put insulated covers on hose bibs.
Cover exposed valves and backflow preventers.
Winterize your sprinkler system and drain it per the manufacturer's instructions.
Insulate exposed pipes in garages, crawl spaces, and basements. Foam pipe sleeves are cheap and easy to put on.
Seal gaps where pipes pass through exterior walls.
Also, find your main water shutoff now. Show everyone in the house where it is. If a pipe bursts, every minute the water runs means more damage.
What should I do during a cold snap?
Keep the heat steady day and night. Don't set it below 55°F, even if you're traveling.
Open cabinet doors under sinks on exterior walls so warm air reaches the pipes.
Let a vulnerable faucet drip slightly overnight. Moving water is less likely to freeze. This helps, but it doesn't replace insulation.
How do I know if a pipe is frozen?
Watch for:
Little or no water from a faucet
Lower water pressure than normal
Frost on an exposed pipe
Banging or gurgling sounds from your plumbing
If you think a pipe is frozen, open the faucet and warm the pipe slowly with a hair dryer or a space heater kept at a safe distance. Never use a torch, lighter, or any open flame. It's a fire risk and can crack the pipe.
What if a pipe bursts?
Shut off the main water valve right away, then call a plumber. Even a small crack can leak a lot of water fast. A 1/8-inch crack can release up to 250 gallons a day.
