The short answer
Keep Pipes Warm
Cold temperatures are the main cause of pipe bursts. When water freezes inside a pipe, it expands and can crack the metal or plastic. During freezing nights, keep cabinet doors open under sinks so warm air reaches the pipes. Keep your thermostat set to at least 55 degrees Fahrenheit, even when you are away from home.
Insulate pipes that run through unheated areas like attics, garages, and crawl spaces. Foam pipe insulation is easy to install and helps maintain a consistent temperature. Seal any gaps or cracks in exterior walls where cold air can reach plumbing. Pay extra attention to pipes on outside walls and near windows.
- Open cabinet doors under sinks during cold snaps
- Keep the thermostat at 55 degrees or higher
- Wrap pipes in foam insulation in unheated spaces
- Seal air leaks around pipes with caulk or spray foam
- Let faucets drip slightly to keep water moving
- Know where your main shutoff valve is located
Drip Faucets in Freezing Weather
A slow drip can prevent a burst. Moving water is less likely to freeze, so let a small trickle run from faucets on exterior walls. Focus on the faucet farthest from your main water line to keep water flowing through the whole system. A steady drip is enough; you do not need a full stream.
If you have pipes that have burst before, take extra care. Drip both hot and cold water lines, since both can freeze. Even a tiny movement of water reduces pressure buildup, which is what actually causes the pipe to crack. Keep this up until outdoor temperatures rise above freezing.
Prepare for Sudden Temperature Drops
Spring thunderstorms and sudden cold snaps can catch you off guard. In a humid subtropical climate, temperatures can swing quickly. Watch weather forecasts and take action before a freeze hits. If you know a cold night is coming, do your prep in the afternoon, not at midnight.
If you leave town during winter, do not shut off the heat completely. Set it to a low but safe level. Ask a neighbor to check your home if you will be gone for a long time. A quick look can catch a small leak before it becomes a major flood.
Know Your Shutoff Valve
Every homeowner should know where the main water shutoff valve is. This valve stops all water entering your home. If a pipe bursts, turning it off quickly limits the damage. Find it now, before an emergency, and test it to make sure it works. Write the location down and share it with everyone in your household.
If you live in Rowlett, keep the shutoff valve location written down near your water heater or on a note in your utility closet. Also know where the shutoff is for outdoor spigots. In an emergency, every second matters. Practice turning the valve so you can do it without thinking.
When a Burst Happens
Even with good prevention, pipes can still break. If you see water spraying or hear a loud bang, shut off the main valve right away. Then turn off the electricity in the affected area if it is safe to do so. Water and electricity are a dangerous mix, so do not enter a room with standing water if the power is on.
After the water is off, call local water damage pros to handle the cleanup. They have the equipment to extract water and dry out your home quickly. Also contact your insurance company to report the damage. Policies vary, and your insurer decides what is covered. Take photos of the damage before any cleanup begins.

What temperature should I keep my house to prevent pipes from freezing?
Keep your thermostat at 55 degrees Fahrenheit or higher, even when you are away. This is warm enough to prevent most pipes from freezing. If you have pipes in unheated areas, add extra insulation and let faucets drip during extreme cold.
Should I shut off my water if I leave for a few days in winter?
It is often wise to shut off the main water valve if you leave for more than a day or two. This prevents a burst pipe from flooding your home while you are gone. Drain the pipes by opening all faucets, then close them once the water stops.
How do I know if a pipe is about to burst?
Look for reduced water flow, strange noises like banging or whistling, and visible frost on exposed pipes. If you notice any of these, act fast. Drip the affected faucet and call a plumber to inspect the system before it breaks.
