Should I Drip My Faucets During A Freeze?

When It Makes Sense

• Good fit: You live in a region where temperatures regularly drop below 20°F (−6°C) and have exposed exterior pipes that lack adequate insulation.
• Good fit: Your home’s heating system is set low or you plan to be away for several days, increasing the chance that interior pipe temperatures will fall below freezing.

When You Should Avoid It

• Warning sign: Your pipes are already well‑insulated, located in heated interior spaces, and local forecasts predict only brief periods above freezing.
• Warning sign: You are in an area with severe water restrictions or drought conditions where any wasteful use of water could incur penalties.

Pros and Cons

Pros

• Maintains a slow flow of water that can keep pipe walls just above the freezing point, reducing the risk of burst pipes.
• Provides a simple, low‑cost method that requires no tools or permanent modifications to your plumbing.

Cons

• Consumes water continuously, which can increase utility bills and may be problematic in areas with water scarcity.
• If not managed correctly, a drip can create a small but steady leak that may cause water damage to cabinets or flooring.

Decision Checklist

• Are any of your water supply lines exposed to unheated spaces (e.g., crawlspaces, attics, exterior walls)?
• Is the expected low temperature prolonged (48+ hours) or are you planning an extended absence?
• Do local water-use regulations or drought conditions make extra water use undesirable?

Alternatives to Consider

Instead of dripping, you can improve pipe protection by adding foam pipe insulation, sealing gaps that let cold air in, or installing heat tape on vulnerable sections. Raising the thermostat a few degrees while you’re away, or leaving cabinet doors open to allow warm air circulation around interior pipes, are low‑water‑use options that address the same risk.

Final Recommendation

If you have uninsulated pipes in a location that will stay below freezing for an extended period, a measured drip (just enough to keep water moving) is a practical safeguard. However, for well‑insulated homes, brief cold snaps, or areas with water restrictions, focus on insulation upgrades and temperature management instead. When in doubt, especially for older plumbing systems, consult a licensed plumber to assess your specific risk profile.
