How to Prevent Frozen Pipes (Knoxville Homeowner Guide)
Frozen pipes aren’t just inconvenient—they can burst and cause serious water damage.
The good news? Most frozen pipe issues are completely preventable with a few simple steps.
Why Pipes Freeze
Pipes freeze when:
Temperatures drop below freezing
Pipes are exposed to cold air
Water sits still inside the line
When water freezes, it expands—and that’s what causes pipes to crack or burst.
5 Simple Ways to Prevent Frozen Pipes
1. Keep Your Heat On (Even When You’re Away)
If you’re leaving home:
👉 Set your thermostat to at least 55°F
This keeps warm air circulating and protects pipes inside walls.
2. Insulate Exposed Pipes
Focus on pipes in:
Crawl spaces
Basements
Attics
Garages
Use:
Foam pipe insulation
Heat tape (for higher-risk areas)
👉 This is one of the most effective prevention steps.
3. Seal Cold Air Leaks
Cold air gets in through:
Cracks around windows and doors
Gaps in walls or foundations
Seal these areas to keep cold air away from your pipes.
4. Let Faucets Drip During Freezing Temps
When temperatures drop significantly:
👉 Let faucets drip slightly
Moving water is much less likely to freeze.
5. Open Cabinet Doors
For sinks on exterior walls:
👉 Open cabinet doors to allow warm air in
This helps protect pipes under sinks—one of the most common freeze points.
Bonus Tip: Don’t Forget Outdoor Plumbing
Before freezing weather:
Disconnect garden hoses
Drain outdoor faucets
Shut off exterior water lines if possible
👉 This prevents freezing where pipes are most exposed.
Warning Signs of Frozen Pipes
Watch for:
Little or no water coming out
Frost on visible pipes
Strange odors from drains
Bulging pipes
👉 If you notice these, act quickly.
What to Do If Pipes Freeze
Turn off the water supply
Avoid using open flames to thaw pipes
Call a professional if you’re unsure
👉 Acting fast can prevent a burst pipe.
When to Call a Plumber
Call if:
You can’t locate the frozen section
Pipes have already burst
Water pressure suddenly drops
You suspect hidden freezing behind walls
