Thawing and freeze damage repair
Frozen pipe repair in Peoria, IL and Peoria, AZ
You turn on the tap on a bitter morning and get a trickle or nothing at all. That is usually ice in the line, not a problem with the water company. Shut off the water, keep the faucet open, and call. A licensed local plumber can thaw the pipe safely and check it for cracks before the leak starts.

Will frozen pipes thaw on their own?
They can, but waiting is risky. When ice blocks a pipe, pressure builds between the ice and the closed faucet, and that pressure is what splits the pipe. The leak often only shows up once the ice melts. Turn off the water to the line, open the faucet, and get the pipe thawed and checked before the weather warms up.
How can you tell a pipe is frozen?
A frozen pipe almost always shows up on the coldest morning of the week. These are the usual clues.
Little or no water from one tap
If the kitchen works but the bathroom on an outside wall doesn’t, ice is the likely cause.
Frost on an exposed pipe
In a basement, crawl space or garage, a pipe with frost or a white coating is frozen inside.
A bulge or crack in the pipe
A swollen section means ice has stretched the pipe. Treat it as a burst waiting to happen.
Odd smells from a drain
When a line is blocked, odors can back up through the nearest drain instead of venting away.
Neighbors have water, you don’t
Illinois American Water says many people think their service is out when the pipes inside are frozen.
Toilet won’t refill
A tank that stays empty after a flush often means the supply line in the wall has frozen.
How do you thaw a frozen pipe safely?
These steps follow Illinois American Water and American Red Cross guidance.
1
Shut off the water first
Illinois American Water says to turn off the water before you thaw. If the pipe has split, this stops a flood the moment the ice melts.
2
Open the faucet
Keep the tap open so melting water and steam can escape and pressure can’t build.
3
Use gentle heat
A hair dryer, heating pad or warm towels work well. Start near the faucet and work back toward the frozen spot.
4
Never use a flame
No torches, propane heaters or open flames. They can start a fire inside the wall or crack the pipe.
Good to know: Turn the water back on slowly and look along the pipe for drips. If you find a split, shut it off again and call a plumber.
Freezing in Illinois, rare freezes in Arizona
One Peoria freezes every winter. The other freezes rarely, which is exactly why its pipes are not ready.
PEORIA, ILLINOIS
Peoria, Illinois: below the danger line every January
Field tests by the University of Illinois Building Research Council found that uninsulated pipes in an unheated space start to freeze when it drops to about 20°F. Peoria’s average January low is 17.6°F, so that line is crossed in a normal winter, not just a bad one.
Bad winters are worse. On January 30, 2019 the National Weather Service recorded a record low of -20°F in Peoria. On New Year’s Day 2018 the high only reached -2°F, and frozen pipe and main break calls followed across the region.
- Pipes in outside walls, under kitchen sinks and in garages
- Crawl spaces and rim joists in pre-1970 homes
- Hose bibs with a hose still attached
- Your meter too: Illinois American Water asks customers to protect it from freezing
PEORIA, ARIZONA
Peoria, Arizona: yes, pipes freeze here too
Freezes are rare in the Valley, but they do happen. Phoenix’s record low is 16°F, and the outer edges of the metro see frost in many winters. Because freezes are rare, most desert homes have no pipe insulation or heat tape.
The City of Phoenix lists the parts that freeze first in Valley homes: irrigation lines, backflow preventers, garden hoses left on hose bibs, garage pipes and plumbing outside the house. During a two-day freeze in 2011, Tucson saw about 3,000 backflow units damaged.
- Cover backflow preventers with foam or a thick blanket
- Remove hoses and wrap exposed outdoor pipes
- Drip a cold tap on freeze-warning nights
- Keep the garage door closed
What does a plumber do for frozen pipes?
The job depends on whether the pipe is only frozen or already cracked.
Safe thawing
Best for: frozen but not split
The plumber warms the line with controlled heat, then tests it under pressure to find hidden cracks before you rely on it.
Split pipe repair
Best for: a crack or burst joint
The damaged section is cut out and replaced. Joints often fail first, so the plumber checks fittings on both sides.
Service line thaw or repair
Best for: no water anywhere in the house
If the line from the curb stop is frozen or broken, it may need special thawing or digging. In Peoria, IL that part of the line belongs to the homeowner.
Freeze-proofing
Best for: a pipe that freezes every year
Insulation, heat cable, a frost-free sillcock or moving a pipe away from an outside wall stops a repeat call next winter.

Check again the day it warms up
Plumbers in cold cities see the same pattern every winter: the calls spike when temperatures rise, not when they fall. A pipe can split at 5°F and stay sealed by ice until the afternoon it climbs above freezing. Then the water comes out all at once.
On the first warm day after a cold snap, take ten minutes to walk your basement, crawl space and garage. Look under sinks on outside walls and listen for dripping. If you find water, shut off the main and call.
How to stop pipes freezing next winter
Most frozen pipe calls are preventable. The American Red Cross says to keep the heat at 55°F or higher, even when you are away. Illinois American Water adds a few simple habits for cold nights.
- Let a thin trickle of water run overnight in very cold weather
- Open sink cabinet doors on outside walls
- Disconnect garden hoses and shut off outdoor faucets
- Insulate pipes in crawl spaces, attics and garages
- Use a freeze alarm that alerts you below 45°F if the house will be empty

The bottom line
In Peoria, IL a frozen pipe is a normal winter risk because January lows sit below the 20°F mark where uninsulated pipes start to freeze. In Peoria, AZ it is rare, but desert homes are not built for it, so outdoor lines and backflow preventers suffer when a freeze hits. Either way, shut off the water, keep the faucet open, use gentle heat only, and check again when it warms up. If a pipe has split or the whole house is dry, call your city’s number for a licensed plumber.
