Freezing weather can strike Texas with little warning. While winters are often mild, sudden cold fronts can bring temperatures low enough to cause costly damage to homes, plumbing systems, and irrigation equipment.
Residents are encouraged to prepare ahead of freezing weather by following the 5 P’s of Freeze Protection: People, Pets, Pipes, Plants, and Property. A little preparation can go a long way in preventing burst pipes, water damage, and expensive repairs.
Why Freezes Cause So Much Damage
When water freezes, it expands. This expansion can cause pipes to crack or burst—especially during a hard freeze, when temperatures remain below 30°F for several hours or longer.
A burst pipe can result in more than just water loss. It may also damage flooring, drywall, furniture, and personal belongings, leading to costly repairs and disruptions.
The 5 P’s of Freeze Preparation
1. People
Stay informed about upcoming weather conditions and take precautions early. Dress in warm layers, limit time outdoors during extreme cold, and use heating equipment safely. If using space heaters, heat lamps, or heat tape, always follow manufacturer instructions and avoid overloading electrical outlets.
2. Pets
Bring pets indoors or provide warm, dry shelter with access to unfrozen water. Freezing temperatures can be just as dangerous for animals as they are for people.
3. Pipes
Protecting your plumbing is one of the most important steps to take before a freeze.
Before temperatures drop:
- Disconnect and drain outdoor hoses. If a hose is already frozen, do not force it loose—it may crack.
- Wrap outdoor faucets and exposed pipes using foam insulation, spigot covers, or towels secured with duct tape.
- Insulate attic pipes, especially those near exterior walls or eaves.
- Check your water meter lid to ensure it is securely closed to help block cold air.
- Open kitchen and bathroom cabinet doors to allow warm air to circulate around indoor plumbing.
- On especially cold nights, allow faucets to drip slowly to help prevent freezing.
If foam insulation or spigot covers are unavailable, towels and duct tape can serve as a temporary solution.
4. Plants
Cover outdoor plants with frost cloths, blankets, or tarps, and bring potted plants indoors when possible. Ensure coverings reach the ground to trap warmth, and remove them once temperatures rise.
5. Property (Including Irrigation Systems)
Irrigation systems and backflow devices are particularly vulnerable during freezing weather.
To help prevent damage:
- Shut off and drain irrigation systems at the backflow preventer.
- Most residential backflow devices have two shut-off valves (often with blue handles) located before and after the device—turn both off completely.
- Release water pressure by opening the bleeder valves using a screwdriver.
- Leave the smaller bleeder valve open so any remaining water can expand without damaging the device.
Many irrigation professionals offer blowout services to remove standing water from lines and reduce the risk of freeze damage.
Stay Ahead of the Weather
Freeze preparation shouldn’t be a last-minute task. Check insulation and protective coverings periodically throughout the winter, and monitor weather forecasts so you can act early when a cold front is expected.
Taking these simple steps can help protect your home, conserve water, and avoid unnecessary repair costs during freezing weather.
