The short answer
Reduced or No Water Flow
A sudden drop in water pressure or a complete lack of flow from a faucet is a primary warning. This typically happens at just one fixture if a single pipe is affected. If multiple faucets are dry, the ice blockage may be in a main supply line. This sign is most obvious when you first use water in the morning after a cold night.
Check fixtures in vulnerable areas first, such as kitchen sinks on exterior walls or bathroom faucets in unheated crawl spaces. Do not force the faucet handle if it seems stuck. A small trickle or sputter of water, rather than a steady stream, also suggests ice is restricting the pipe. This is the time to take action before pressure builds and causes a rupture.
Visible Frost and Strange Odors
Check exposed pipes in basements, attics, and under cabinets for a layer of frost or heavy condensation. This is a clear visual clue that the water inside is at or below freezing. Copper pipes may show a white, frosted appearance, while plastic pipes might look swollen or distorted. Even a small section of frost indicates a risk of the pipe freezing solid.
- Frost or ice on the outside of a pipe.
- Condensation or sweating on a cold pipe surface.
- A visibly swollen or bulging section of pipe.
- A strange gurgling sound when you flush a toilet.
- Foul odors coming from a sink or floor drain.
- A toilet that won't refill after flushing.
Unusual Sounds and Bulging Pipes
Listen for banging, clanging, or creaking noises when you turn on a tap. These sounds can mean ice is expanding and moving inside the pipe, creating stress points. Gurgling or bubbling noises from drains suggest an air blockage caused by ice further down the line. If you hear a loud pop or crack, a pipe may have already burst, and you should locate your main water shutoff immediately.
In severe cases, the pipe itself may show physical changes. Look for any section that appears slightly expanded or misshapen compared to the rest of the line. This bulging occurs where ice has formed and created immense internal pressure. A pipe in this state is at extreme risk of bursting at any moment. If you see this, shutting off the water supply is the safest first step.
What to Do If You Suspect a Freeze
If you notice a warning sign, your first move is to locate and turn off the main water shutoff valve for your home. This prevents a massive flood if a frozen pipe does burst open. Then, open the faucet connected to the frozen pipe to relieve any remaining pressure. You can attempt to gently thaw the pipe with a hair dryer, starting from the faucet end and working back.
Never use an open flame or a high-heat device like a blowtorch, as this can damage pipes and create a fire hazard. If you cannot access the frozen section or the pipe has already burst, you need professional help. Water damage from a burst pipe can ruin drywall, flooring, and personal belongings very quickly. Calling local water damage pros for emergency water extraction can prevent widespread structural issues.
Preventing Frozen Pipes in Your Home
Prevention is the most effective strategy against frozen pipes. Insulate pipes in unheated areas like attics, garages, and crawl spaces with foam sleeves. During a cold snap, let a small trickle of water run from faucets served by vulnerable pipes. Keep cabinet doors open under sinks to allow warm room air to circulate around the plumbing. If you leave town in winter, do not set your thermostat below 55 degrees Fahrenheit.
Know the location of your main water shutoff valve and how to use it. If you live in DeSoto, keep your shutoff valve location written down. Disconnect and drain outdoor garden hoses before winter, and shut off the indoor valve supplying outdoor faucets. Sealing air leaks in your home's exterior, especially where pipes enter, can also keep cold drafts away from your plumbing. A little preparation can save you from costly water damage repairs.

At what temperature do pipes typically freeze?
Pipes are at risk of freezing when temperatures stay at or below 20 degrees Fahrenheit. However, pipes on exterior walls or in unheated spaces can freeze when it's consistently below 32 degrees, especially during a long cold snap. Wind chill and poor insulation greatly increase the risk, so it's best to take precautions before a hard freeze is forecast.
Can a frozen pipe thaw on its own?
A frozen pipe may thaw on its own when outdoor temperatures rise. This is actually a dangerous period, as the thaw can reveal a crack that formed when the pipe was frozen. The water will then leak as it melts. It's safer to control the thawing process yourself with gentle heat and to monitor the pipe closely for leaks.
Who should I call for a burst pipe?
First, call a plumber to repair the broken pipe and stop the water source. Then, contact local water damage pros for water extraction, drying, and damage mitigation. They have the equipment to remove standing water, dry out walls and flooring, and help prevent mold. These are two different trades, and you will likely need both.
