Keep Your Home Safe: Dripping Faucets to Prevent Frozen Pipes

As winter temperatures plunge, homeowners are considering effective measures to prevent frozen pipes. Experts recommend a simple yet effective technique: dripping faucets. Knowing the right conditions for this practice, specifically when to start and which faucets require attention, can make the difference between safeguarding your home and incurring costly repairs.

Understanding the Risks of Frozen Pipes

When temperatures drop to 20°F (-6°C) or below for several hours, the risk of pipes freezing increases significantly. According to the National Weather Service, this temperature serves as a critical threshold where ice formation becomes a real threat. A frozen pipe can lead to serious issues, including ruptures, which may result in extensive water damage and costly repairs.

Allowing water to drip from affected faucets keeps it moving through the pipes, making it more difficult for ice to develop. Additionally, dripping helps alleviate pressure that builds up when water freezes. If ice forms and seals both ends of a pipe, the pressure from expanding ice can cause the pipe to burst.

How to Properly Drip Your Faucets

To effectively protect your plumbing, there are several important steps to follow:

1. **Know When to Start Dripping**: Monitor weather forecasts and begin dripping faucets when temperatures are expected to reach 20°F or lower, particularly overnight.

2. **Identify At-Risk Faucets**: Focus on faucets connected to pipes in unheated areas or those along exterior walls. These include bathrooms and kitchens located on outside walls, as well as utility sinks in garages or basements. Interior pipes generally remain safe due to your home’s heating.

3. **Control the Drip Rate**: Aim for a slow, steady trickle—about the thickness of a pencil lead. If you have separate hot and cold handles, turn both slightly to ensure both sets of pipes are protected. For single-handle faucets, position the handle in the middle to draw water from both supplies. A proper drip should produce individual drops that merge into a thin stream, avoiding excessive waste.

4. **Open Cabinet Doors**: A surprisingly effective method is to open cabinet doors under sinks along exterior walls. This allows warm air from your home to circulate around the pipes, preventing cold air from accumulating.

5. **Protect Outdoor Faucets**: For outdoor spigots, which require different treatment, shut off the dedicated valve if available, typically found in the basement or utility room. Open the outdoor faucet to drain any remaining water. Disconnect garden hoses to prevent trapped water from freezing and damaging the spigot. If no shutoff valve exists, insulate each spigot with old towels or foam faucet covers available at hardware stores.

By following these guidelines, homeowners can avoid the headaches associated with frozen pipes. Taking proactive measures, particularly before the frost hits, can save both time and money in the long run.

As temperatures continue to drop this winter, make sure to apply these tips to keep your home safe and warm.
