Winter Storm Warning: How to Protect Your Pipes January 23, 2026
When a winter storm moves in, freezing temperatures can put significant stress on your home’s plumbing system. Frozen pipes, burst pipes, and even a broken water heater are common during prolonged cold weather, especially in homes that are not designed for sustained freezes.
Taking a few proactive steps now can help reduce the risk of damage and costly repairs later.
Why Winter Storms Put Your Pipes at Risk
Water expands when it freezes. When temperatures drop low enough, any water sitting inside plumbing lines can freeze, expand, and place pressure on the pipe walls. This is especially dangerous in areas where plumbing runs through exterior walls, crawl spaces, garages, or cabinets with poor airflow.
Pipes often do not burst at the moment they freeze. The real damage frequently happens when temperatures rise and the ice thaws, allowing water to escape through cracks or splits that formed during the freeze.
What to Do Before Temperatures Drop
Preparation is critical because once pipes freeze, options become limited.
- Disconnect outdoor hoses so water cannot remain trapped inside exterior plumbing.
- Cover outdoor spigots with a spigot cover or wrap them securely with a towel to block cold air.
- Open cabinet doors under sinks to allow warm air from the home to circulate around supply lines.
- Locate and insulate or block drafts around exposed plumbing in garages, crawl spaces, or utility rooms.
- Stream a small flow of hot AND cold water from your faucets to keep water flowing in your pipes.
These steps work because they reduce the amount of cold air reaching your plumbing and help maintain temperatures above freezing in vulnerable areas.
How to Run Water Safely to Prevent Frozen Pipes
Many homeowners ask “when should you drip your faucets?” during a freeze. While dripping is often mentioned, we recommend something slightly different.
A small, steady stream of both hot and cold water is more effective than a drip.
- Moving water is less likely to freeze than standing water
- Running both hot and cold lines helps protect the entire section of piping, not just one side
- This is most important overnight and during the coldest hours
This method helps relieve pressure inside the line and keeps water flowing through sections most at risk for freezing.
How to Protect Indoor and Outdoor Plumbing During a Winter Storm
Once the storm is underway, consistency matters.
- Keep indoor temperatures stable, even overnight
- Leave cabinet doors open where plumbing is located
- Make sure spigot covers stay in place and dry
- Avoid shutting off heat to unused areas of the home
Frozen pipes are often found in homes where one area was left unheated or airflow was restricted. Maintaining warmth and circulation throughout the house is key.
What to Do If Your Pipes Freeze
If you suspect frozen pipes, act carefully and quickly.
- Shut off the main water supply if possible
- Open the affected faucet to relieve pressure
- Apply gentle heat using a hair dryer, warm towels, or a space heater placed safely nearby
- Never use open flames or high heat sources
If water does not return or you are unsure where the freeze is located, call a professional. Frozen lines can burst as they thaw, and situations like this often require emergency plumbing service to prevent further damage.
Warning Signs of a Burst Pipe or Plumbing Damage
Burst pipes are not always obvious right away. Watch for:
- Sudden drops in water pressure
- Unusual sounds behind walls or ceilings
- Visible leaks, damp spots, or water stains
- Musty or wet odors
If you notice any of these signs, shut off the water immediately and contact a plumber.
How Freezing Temperatures Can Damage Your Water Heater
Water heaters are also vulnerable during a winter storm. Frozen supply lines can restrict water flow and increase internal pressure. Over time, this can damage components such as valves, fittings, and in some cases the heat exchanger.
A cracked or broken heat exchanger can prevent proper heating, cause leaks, or lead to complete system failure once temperatures rise. Water heaters located in garages or unheated spaces are especially at risk during prolonged freezes.
When to Call a Professional During a Winter Storm
Some situations require professional help right away.
Call a plumber if:
- You suspect frozen pipes but cannot locate them
- There is no water flow after attempting safe thawing
- You see signs of burst pipes or water damage
- Your water heater stops working or begins leaking
