How to Prevent Frozen Pipes in Knoxville (Winter Plumbing Checklist)
Winter in East Tennessee can be unpredictable—and your plumbing feels it first.
When temperatures drop, pipes can freeze, expand, and burst, leading to expensive water damage.
The good news: most winter plumbing problems are preventable with a few simple steps.
Winter Plumbing Checklist for Knoxville Homes
1. Insulate Exposed Pipes
Pipes in unheated areas are the most at risk.
Focus on:
Crawl spaces
Basements
Garages
Exterior walls
Use foam insulation or heat tape to protect them from freezing temperatures.
2. Seal Cold Air Leaks
Cold air reaching your pipes increases the risk of freezing.
Check for gaps around:
Doors and windows
Crawl space openings
Exterior walls
Sealing these areas protects both your plumbing and your heating efficiency.
3. Let Faucets Drip During Freezing Nights
When temperatures drop below freezing:
Let faucets drip slightly
Keep water moving through the pipes
This relieves pressure and helps prevent freezing.
4. Keep Your Home Heated
If you’re leaving town:
Don’t turn the heat off
Keep your thermostat set to a safe temperature
Even a small amount of heat can prevent major damage.
5. Disconnect and Drain Outdoor Faucets
Before freezing weather hits:
Remove garden hoses
Shut off outdoor water lines (if available)
Drain remaining water
This prevents freezing and pipe cracking.
6. Fix Leaks Before Winter Hits
Even small leaks increase the risk of freezing.
Check for:
Dripping faucets
Moisture under sinks
Visible pipe leaks
Fixing them early reduces winter risk.
7. Maintain Your Water Heater
Your system works harder in winter.
Before cold weather:
Flush sediment buildup
Check for performance issues
Make sure it’s heating efficiently
