Tips to Protect Residential Pipes for Winter Conditions

CAMDEN, N.J., Dec. 4, 2025 /PRNewswire/ -- As winter approaches, American Water (NYSE: AWK), the largest regulated water and wastewater utility company in the U.S., reminds customers and the general public to prepare their home, providing handy tips to help avoid costly repairs and unwanted stress from frozen pipes.

"Customers should take steps to protect their pipes from freezing as temperatures are beginning to drop as we enter the winter months," said Mike Doran, Senior Vice President, Deputy Chief Operating Officer & Chief Health and Safety Officer, American Water. "Taking time to prepare and also regularly checking on your pipes during extremely cold days will help ensure you and your loved ones stay safe and comfortable this winter."

Customers can prepare by taking the following steps:

• Know how to shut off your water: Locate your main water shut-off valve. In many homes, it is located near the water meter or close to where the water pipe enters the home. Hang an I.D. tag on the valve so it can be found quickly during an emergency. Download a tag to print here.
• Test your main water shut-off valve: Once located, test the shut-off valve by closing it. Once completely closed, check sinks and other water fixtures to ensure the shut-off valve is working properly.
  • Ball valves generally only require a quarter turn to close.
  • Gate valves are generally closed by turning the handle clockwise and should turn easily.
  • If the valve does not close easily, it may need to be serviced.
• Check sprinkler or irrigation systems: Make sure everything is turned off and fully drained.
• Eliminate sources of cold air near water lines: Check for pipes in areas that might be prone to freezing, such as crawl spaces, unheated rooms, basements, garages, and exterior walls. Fix drafty windows, insulate walls around pipes and plug drafts around doors.
• Protect your pipes: Where pipes are exposed to cold, wrap them with insulation or heat tape (even fabric or newspaper can help).

When temperatures stay below freezing:

• Give pipes a helping hand: If pipes run through cabinets or vanities, open the doors to let warmer room temperatures flow in.
• Keep water moving through the pipes: Allow a small trickle of water to run. The cost of the extra water is typically lower than the cost of repairing a broken pipe.

If pipes freeze:

• Shut off the water immediately: Do not attempt to thaw pipes without turning off the main water shut-off valve.
• Thaw a frozen pipe by warming the air around it: Use a hair dryer, space heater or hot water. Do not leave space heaters unattended and avoid using kerosene heaters or open flames.
• Once pipes are thawed: Slowly turn the water back on. Check pipes and joints for any cracks or leaks potentially caused by freezing.

When customers are away from home, consider the following:

• Set your thermostat at 55 degrees to prevent freezing.
• Have a friend, relative or neighbor regularly check the property to help ensure the heat is working and the pipes have not frozen.
• Consider purchasing a freeze alarm. The alarm will call a user-selected phone number if the inside temperature drops below 45 degrees.

Additionally, American Water is working with customers to identify their service line material. As customers prepare their pipes for cold weather, they can check whether their service line is made of lead or galvanized steel.
