Central Pennsylvania winters don’t play around. When temperatures dip into the teens and single digits, a common occurrence from Harrisburg to York to Lancaster, frozen pipes become one of the most common and destructive home emergencies. A pipe that freezes for just a few hours can quickly expand, crack, and burst, unleashing hundreds of gallons of water inside walls, ceilings, or basements.
If you wake up to no water, weak flow, or the dreaded sound of rushing water behind a wall, you need to act fast. A frozen pipe emergency is stressful, but responding the right way can dramatically reduce damage and repair costs. Pronto Plumbing, Heating, Air & Drains has been rescuing Central PA homeowners from frozen pipe disasters for decades. Here’s exactly what to do if you suspect a frozen pipe, and when to call in the experts at Pronto immediately.
Why Frozen Pipes Are an Emergency
- Frozen Pipes Can Burst Without Warning: When water freezes, it expands. Inside a confined pipe, that pressure can split copper, PVC, or PEX lines wide open. Even a hairline fracture becomes a full leak the moment the ice thaws.
- Damage Spreads Fast: A single burst pipe can fill a basement or soak an entire wall cavity in minutes. That water can destroy drywall, insulation, carpet, flooring, and electrical systems.
- Central PA Weather Makes Damage More Likely: With long stretches below 32°F, especially overnight, homes in Harrisburg, York, and Lancaster are at high risk for pipes freezing solid.
- Early Action Can Save You Thousands: Knowing what to do (and what not to do) during the first few minutes of a burst pipe is key to protecting your home.
What To Do Immediately If You Have a Frozen Pipe
1. Shut Off Your Home’s Main Water Supply
This is the single most important step. Turning off your water prevents flooding if the frozen pipe cracks as it thaws. Locate the main shutoff valve (usually near the water meter or where the main line enters the home). Turn it clockwise to close. If your valve is hard to reach or stuck, stay calm, Pronto can help.
2. Open Nearby Faucets to Relieve Pressure
Even if water isn’t flowing, open both the hot and cold sides of affected faucets. This relieves pressure and gives thawed water somewhere to escape safely.
3. Locate the Frozen Section (If You Can Do So Safely)
Common freeze points in Central PA homes include:
- Pipes along exterior walls
- Uninsulated crawl spaces
- Garages
- Basements
- Attics
- Under kitchen or bathroom sinks
- Outdoor hose bibs
Don’t start cutting walls, just do a visual inspection in accessible areas.
4. Use Safe Thawing Methods – Never Use Open Flame
You can attempt gentle thawing if the pipe is accessible and NOT burst:
Approved methods:
- Hair dryer on low heat
- Space heater placed several feet away
- Warm (not boiling) towels
- Heating pad on low
Never use:
- Propane/kerosene torches
- Lighters
- Open flame of any kind
- High-heat tools
These are major fire hazards and often cause pipes to burst from rapid expansion.
5. Check for Leaks As the Pipe Thaws
Once water begins to flow again, inspect the pipe carefully.
Look for:
- Drips
- Spraying water
- Damp walls or ceilings
- Unusual sounds
Even a slow leak requires immediate professional attention.
