Pipes don’t need subzero weather to freeze. Plumbing exposed to cold air is at risk once temperatures fall below 32°F, and pipes most often freeze at 20°F or below. In Wichita, January’s average daily low is 22.5°F, so a cold night can threaten poorly protected plumbing before a burst pipe gives any visible warning.
We’ve served Wichita property owners since 2000, and we know winter problems often start in overlooked parts of a building: an uninsulated crawl space, an exterior-wall cabinet, an attic line, or the pipe feeding an outdoor faucet. A few focused steps before a cold snap can protect these vulnerable areas.
Know When Wichita Pipes Are at Risk
Freezing water expands by more than 9 percent. That expansion creates pressure inside a pipe, which can crack or break the material. A pipe can crack while frozen and not begin leaking until the ice thaws.
Start by identifying plumbing that receives little protection from heated indoor air.
Check these locations before temperatures drop:
- Exposed water lines in crawl spaces, attics, and unheated utility areas.
- Kitchen and bathroom sink cabinets located on exterior walls.
- Outdoor faucets, hose bibs, and the interior pipes that serve them.
- Openings around pipes, wiring, vents, and foundation penetrations.
Prepare Vulnerable Plumbing Before a Freeze
Insulation works best when cold outdoor air is also kept away from the pipe. Pipe insulation is especially useful in crawl spaces and attics, where indoor heat may not reach plumbing consistently. Measure the pipe diameter, use insulation designed for plumbing lines, and secure the seams so the material stays in place.
For a particularly exposed line, heat tape or thermostatically controlled heat cable can provide another layer of protection when installed exactly as the manufacturer directs. Don’t use damaged cords, overlap heat tape unless the instructions permit it, or cover the system in a prohibited way.
Small air leaks also deserve attention. A gap around a dryer vent, electrical wiring, or plumbing penetration can direct freezing air onto a short stretch of pipe. Seal appropriate gaps with caulk or insulation while preserving any ventilation required for appliances or building systems.
Disconnect garden hoses from outdoor faucets before freezing weather arrives. If the faucet has an indoor shutoff, close it, open the outside faucet, and drain the remaining water from the line. An attached hose can trap water at the faucet and increase the risk of damage just inside the wall.
Protect Pipes During a Cold Snap
When a hard freeze is forecast, use this checklist to keep warm air around vulnerable plumbing and catch warning signs early:
- Open cabinet doors around exposed sink plumbing, especially on exterior walls.
- Let vulnerable faucets run at a slow drip during prolonged freezing temperatures.
- Close garage doors and exterior access doors to limit cold-air exposure.
- Check rarely used bathrooms, utility rooms, and vacant units for reduced water flow.
A slow drip keeps water moving, brings relatively warmer water into the line, and relieves pressure if ice begins to form farther along the pipe. You don’t need to drip every faucet. Focus on those served by pipes in exterior walls or unheated areas, and keep the thermostat at a steady setting overnight.
If you’ll be away from a home or rental property, set the thermostat no lower than 55°F. Ask a neighbor, tenant, or property contact to check the building daily during a freeze because a leak may not be obvious from outside.
Plan for a Power Outage & Detect Leaks Early
A power outage removes the heat that protects indoor plumbing. If an outage is expected to last long enough for the building to become cold, closing the main water valve and draining the plumbing system reduces the amount of water available to freeze and leak later.
Every household member or property manager should know where the main shutoff is and how it operates. A ball valve closes with a quarter turn and is open when its handle runs parallel to the pipe. Make sure you can reach it, but don’t force a corroded or stuck valve.
Once the main supply is closed, open faucets from the top floor downward and flush toilets to help drain the lines. Close and drain the interior shutoffs for outdoor faucets as well. If you’re unsure how the building’s plumbing is configured, get professional guidance before an outage becomes an emergency.
A water leak alarm placed near a water heater, washing machine, or under-sink plumbing can alert you as soon as it detects water. It won’t prevent a freeze, but early detection can limit how long a leak runs unnoticed.
Respond Safely to Frozen or Burst Pipes
A faucet that produces only a trickle or no water can indicate a frozen pipe. Check other faucets because multiple lines can freeze during the same cold event. Continue watching the suspected area as water flow returns because a cracked pipe can begin leaking after thawing starts.
Attempt basic thawing only when the frozen section is reachable, dry, and free of visible damage. Leave the affected faucet open and use a hair dryer, working from the faucet toward the coldest section. Never use a torch, open flame, propane heater, or other direct flame on a pipe. If the pipe doesn’t thaw with this method, stop and contact a professional.
Treat the situation as an emergency if you see water, hear it running inside a wall, find a crack, or encounter standing water. Shut off the main water supply when it’s safe to do so, then contact a professional. Never use electrical appliances near standing water.
Our response starts with water control and safe, controlled thawing when appropriate. We then repair the plumbing and inspect for hidden moisture. Because we provide plumbing and water damage restoration under one roof, we can address both the failed pipe and the water it released.
Keep a Simple Winter Plumbing Plan
Before the next freeze, walk through the property to protect exposed pipes, confirm that heat can reach vulnerable plumbing, and locate the main water shutoff. During cold weather, watch for reduced water flow and leaks so you can act before damage spreads.
