Let faucets drip during severe cold

Allowing faucets to drip during extreme cold keeps water moving through vulnerable pipes and relieves pressure that builds between the faucet and any ice forming inside the line. Even a slow, steady drip is enough to prevent a burst.

Steps

1. Identify faucets served by pipes running through unheated areas or along exterior walls.
2. Open both hot and cold handles just enough to produce a slow, steady drip.
3. Maintain the drip overnight and whenever temperatures stay below 20°F (−6°C).
4. Place a container under the faucet to collect water and reduce waste.

Tips

• Focus on the faucet farthest from where the main water line enters the house; this keeps water moving through the longest pipe run.
• The small increase in your water bill is negligible compared to repairing a burst pipe.
• If the drip slows or stops on its own during a cold snap, a partial ice blockage may be forming — call a plumber promptly.
