Know where the water shuts off
Locate the home’s main water shutoff before freezing weather arrives. Make sure the responsible adults in the household know where it is and how it operates. Do not force a stuck or heavily corroded valve. If a pipe breaks, quickly stopping the water can limit damage while you arrange a repair.
Protect exposed plumbing
Disconnect garden hoses and follow the manufacturer’s instructions for outdoor faucets, backflow devices, and irrigation systems. Insulate accessible pipes in unheated areas such as garages, exterior walls, or cabinets where appropriate. Use products intended for plumbing insulation and keep heat sources away from combustible materials.
Keep indoor heat moving
Maintain indoor heat and avoid turning the thermostat down sharply overnight. Opening cabinet doors beneath sinks on exterior walls can help warmer room air reach nearby plumbing. Keep household chemicals and cleaners out of the reach of children and pets when cabinets are open.
Should faucets drip?
A small flow may help in some situations, especially for a vulnerable line, but it is not a guarantee against freezing and is not appropriate for every plumbing layout. Follow guidance from local officials and your plumbing professional. Address known insulation gaps or exposed piping rather than relying only on a dripping faucet.
If a pipe appears frozen
A faucet with little or no flow during a freeze may indicate a frozen section. Turn off the water if you see a crack, bulge, or active leak. Never use an open flame to thaw a pipe. Gentle warming and professional help are safer; hidden damage may begin leaking after the ice melts.
After temperatures rise
Inspect exposed pipes, cabinets, ceilings, walls, and outdoor connections for moisture. Listen for unexpected water movement and check whether your meter shows use when fixtures are off. A slow leak can cause damage even when there was no dramatic burst. Our leak detection, water-line, and emergency plumbing pages explain available help.
