How to Tell if Your Pipes Are Frozen
What’s tricky about frozen lines is that the problem is not always obvious. In many cases, the issue remains hidden until we have a frozen or burst pipe. This can cause a significant amount of damage not only to your home, but to your yard as well, and result in costly clean-ups. However, there are some signs that may cue you in on a problem:
- Slow-moving water. If the water flowing from your faucets and shower heads is moving at a slower rate than normal, call a licensed plumber trained in diagnosing these problems.
- Odd sounds. There may be bubbling noises when you flush the toilet or turn on the sink. Whistling or clanking could indicate that a pipe is dented and the water cannot easily pass through.
- Icy pipes. When frost forms on your pipes, that is a dead giveaway that there is an issue.
- Bulging pipes. If your pipe is bulging like a python that has just had lunch, your pipes could be frozen.
If You Have Frozen Pipes
To minimize the damage, it is important to take the following steps if you have a frozen pipe:
- Turn off the water main: Too much pressure on frozen pipes can cause the pipes to burst. If the water is on and the pipes burst, flooding can be significant.
- Thaw the ice if the affected pipe is visible: Put your hairdryer or space heater to work to thaw the ice in the exposed pipe.
- Call a licensed plumber immediately: If you notice your water is flowing more slowly than normal, you may have a frozen pipe. Take care of the issue before serious damage ensues.

How to Prevent Them From Freezing in the First Place
The average frost line depth is about 36 inches in both Salt Lake County and Utah County. This means that to keep the main water line in your front yard from freezing, you need to make sure it is buried deep enough.
People often ask us why they have a frozen line one year, but not the next. There are many reasons for this, as well as different solutions. Mainly, it has to do with how cold your pipes get and if you have water flowing through the system. In some cases, a simple fix will do the job, and other times you will need to change how your piping is run.

Outdoor spigot won't shut off after winter — pipe inside the wall is cracked

Pipe sweating heavily right after a deep freeze

The Process
How a Frozen Pipe Call Works
Shut off and isolate
Tech finds your main shutoff, isolates the affected branch, and protects everything below the freeze with drop cloths. If a pipe is already leaking, water-off is the first 30 seconds.
Locate the freeze
Trace the cold section by hand and infrared thermometer. We map the run, find the freeze point, and identify any obvious cracks before thawing begins.
Thaw safely
Electric pipe thawing machine for copper and galvanized. Warm-air or hot-water circulation for PEX and CPVC. Never open flame — that's how homes burn during a freeze.
Pressure-test for cracks
Once the line is liquid again, we restore pressure with the main partly open and watch for hidden fractures. Micro-cracks often don't show until water flows.
Repair or replace
Single-point crack in an accessible spot = SharkBite or soldered coupling, 30-60 minutes. Long damaged run or polybutylene/galvanized = full replacement with modern PEX-A or copper.
Reinforce the run
Insulate exposed pipe with closed-cell foam, install heat tape with thermostat in cold zones, seal the air leak that caused the freeze. Same freeze does NOT happen twice.
