When winter temperatures plunge across Central Indiana, your home’s plumbing system faces serious risks. Frozen pipes aren’t just an inconvenience—they can burst and cause thousands of dollars in water damage within hours. Understanding how to prevent frozen pipes and knowing what to do when they occur can save you from a costly disaster.
Why Indiana Homes Are Vulnerable to Frozen Pipes
Water freezes at 32°F, but your pipes typically don’t face serious risk until outdoor temperatures drop to 20°F or below for at least 4-6 consecutive hours. In Central Indiana, we experience these conditions regularly during winter months, putting local homes at significant risk.
When water freezes inside a pipe, it expands, creating tremendous pressure against the pipe walls. Interestingly, the pipe doesn’t usually burst at the frozen spot itself. Instead, pressure builds between the ice blockage and a closed faucet downstream, causing the pipe to crack or burst at its weakest point—often where you least expect it.
The pipes most vulnerable in Indiana homes include:
- Outdoor hose bibs and spigots
- Swimming pool and sprinkler supply lines
- Pipes running through unheated spaces like garages, basements, crawl spaces, and attics
- Pipes installed along exterior walls with little insulation
- Water supply lines in older homes with less effective insulation
Seasonal Prevention: Preparing Your Home Before Cold Weather Strikes
The best defense against frozen pipes is preparation. Take these preventative steps before temperatures drop:
Outdoor Plumbing Winterization
Disconnect and drain garden hoses. Store them indoors for the winter. Water trapped in connected hoses can freeze and damage both the hose and the spigot.
Shut off and drain outdoor faucets. If possible, use an indoor valve to shut off water supply to exterior faucets, then open the outdoor faucet to drain any remaining water.
Install foam faucet covers. These inexpensive styrofoam covers provide an extra layer of protection for outdoor spigots. You can find them at any hardware store.
Consider upgrading to frost-free hose bibs. These specialized outdoor faucets have shutoff valves located farther inside your home where it’s warmer, significantly reducing freeze risk. A plumber can typically install these affordably.
Indoor Pipe Protection
Insulate vulnerable pipes. Apply foam pipe insulation sleeves to exposed pipes in unheated areas. Focus on pipes in your basement, crawl space, attic, and garage. Even a quarter-inch of newspaper wrapped around pipes can provide meaningful protection.
Seal air leaks. Use caulk or expanding foam to seal gaps around pipes where they enter your home from outside. Check for openings around electrical wiring, dryer vents, and cable lines—even small gaps can let in enough cold air to freeze pipes.
Install heat tape or heat cables. For pipes in especially vulnerable locations, UL-listed heat tape with a thermostat can provide active warming when temperatures drop. Always follow manufacturer’s installation instructions carefully.
Keep garage doors closed. If you have water supply lines running through your garage, keep doors closed to retain any available heat.
Thermostat Management
Maintain consistent temperatures. Set your thermostat to at least 55°F, even when you’re away from home or sleeping. While this may increase your heating bill temporarily, it’s far less expensive than repairing burst pipes and water damage.
Don’t set back your thermostat during cold snaps. On nights when temperatures are forecasted to drop into the teens, consider raising your thermostat a few degrees rather than lowering it. This ensures warmer air reaches all areas of your home.
When Temperatures Drop: Active Protection Strategies
When the forecast shows prolonged periods below 20°F, take these additional protective measures:
Let faucets drip. Allow a slow trickle of water to run from faucets served by vulnerable pipes, especially those on exterior walls. Moving water is much less likely to freeze, and an open faucet relieves pressure if ice does form, reducing the chance of a burst. Run cold water—you don’t need hot water dripping.
Open cabinet doors. Open doors under bathroom and kitchen sinks to allow warm room air to circulate around pipes. Be sure to move any cleaning products out of reach of children and pets.
Direct heat to cold areas. Use a space heater (placed safely away from flammable materials and standing water) to add warmth to especially cold rooms or areas with exposed pipes.
Ask someone to check your home. If you’ll be traveling during cold weather, have a neighbor or friend check your home daily to ensure it’s staying warm enough.
Recognizing the Warning Signs of Frozen Pipes
Early detection can prevent a frozen pipe from becoming a burst pipe. Watch for these warning signs:
- Reduced or no water flow from faucets when you turn them on—especially from only one faucet or area
- Frost visible on exposed pipes, particularly in basements, crawl spaces, or along exterior walls
- Strange sounds like whistling, banging, or gurgling when you run water
- Unpleasant odors from drains (if the water in a trap freezes, sewer gases can back up)
- Unusually cold spots on walls or flooring near plumbing lines
If you notice any of these signs, take immediate action to prevent a burst.
Emergency Steps: What to Do If Your Pipes Freeze
If you discover a frozen pipe, acting quickly can prevent it from bursting and causing extensive damage:
Immediate Actions
1. Turn on the affected faucet. Keep it open—when you begin thawing the pipe, water and steam need somewhere to go. An open faucet also relieves pressure in the system.
2. Locate your main water shutoff valve. Know where it is in case the pipe has already burst or bursts during thawing. It’s typically located near your water meter or where the main line enters your home.
3. Check for visible damage. If you can access the frozen pipe, look for cracks, bulges, or ice seeping out. If you see any of these signs, shut off your main water valve immediately and call a professional plumber.
Safe Thawing Methods
If the pipe appears intact and you can safely access it, you may attempt to thaw it using these methods:
Safe heat sources include:
- Hair dryer on low setting (keep it away from water and flammable materials)
- Space heater placed nearby (never left unattended)
- Heating pad wrapped around the pipe
- Hot towels wrapped around the pipe
Start closest to the faucet and work backward toward the frozen section. This allows melting water to flow out through the open faucet.
NEVER use these dangerous methods:
- Open flames (torch, candles, matches)
- Propane or kerosene heaters near pipes
- Boiling water poured directly on pipes
- Leaving anything with electricity unattended or in/near water
When to Call a Professional Immediately
Some situations require professional help right away:
- You can’t locate the frozen pipe
- The frozen pipe is inside a wall or ceiling
- You see signs of a burst (water leaking or spraying)
- Multiple faucets have no water flow
- You’re uncomfortable attempting to thaw the pipe yourself
- You’ve tried safe thawing methods without success
If a Pipe Bursts: Critical Emergency Response
A burst pipe requires immediate action to minimize water damage:
Step 1: Shut off your main water valve immediately. This stops water flow to the entire house. Every second counts—a burst pipe can release hundreds of gallons of water.
Step 2: Turn off electricity to affected areas if water is near outlets, appliances, or your electrical panel.
Step 3: Open all faucets to drain remaining water from the system and relieve pressure.
Step 4: Document the damage with photos and videos for your insurance claim.
Step 5: Begin water removal using towels, mops, and buckets to prevent mold growth and additional damage.
Step 6: Call a professional plumber for emergency repair services.
