PLUMBING IN A HEATWAVE: WHAT EVERY EAST TENNESSEE HOMEOWNER SHOULD KNOW

Plumbing in a Heatwave: What Every East Tennessee Homeowner Should Know

When the summer heatwave hits Knoxville and East Tennessee, most homeowners think about their air conditionersm, but your plumbing system also feels the strain. Extreme heat, increased water use, and rising ground temperatures can all impact how well your pipes, fixtures, and water systems hold up during the hottest days of the year.

Here’s how heatwaves affect your plumbing—and what you can do about it.

Common Plumbing Problems During A Heatwave

1. Pipe Expansion and Leaks
Just like metal expands in heat, so do your pipes. As temperatures soar, your outdoor and exposed plumbing can swell, increasing the risk of small cracks, leaks, or even bursts—especially in older systems.

2. Overworked Water Heaters
Summer might not seem like a heavy water-heating season, but with more showers, laundry, and dishwashing, your water heater can still struggle. If your unit is aging or not properly maintained, it may fail when you need it most.

3. Sewer Line Trouble
Drought-like conditions can dry out the soil, causing it to shift and potentially crack underground sewer lines. This can lead to backups, slow drains, or foul odors around your home.

4. Clogged Drains from Outdoor Activity
Heatwaves often mean more people at home, more outdoor play, and more dirt, sand, and grease heading down your drains. This added usage increases the chance of clogs and backups, especially in kitchen and shower drains.

5. Water Pressure Fluctuations
High water demand in your neighborhood can reduce your water pressure—or in some cases, strain your home’s main supply line. If pressure seems low or inconsistent, don’t ignore it.

Key Points To Know:

• High temps can expand pipes and create leaks, especially in older plumbing
• Sewer lines are at risk from dry, shifting soil
• Extra summer usage puts stress on water heaters and drains
• Low water pressure or slow drains may signal a deeper issue
• Preventative maintenance now can save costly repairs later

Heatwave Plumbing Tips

• Inspect visible pipes and hoses for bulges, leaks, or cracks
• Flush slow drains with safe cleaners or call for a professional cleaning
• Limit debris in your drains by rinsing off outdoors before showering
• Check your water heater for warning signs like strange noises or rust
• Schedule a plumbing inspection to catch hidden issues early

Conclusion 

Extreme heat can do more than overwork your A/C, it can quietly damage your plumbing too. Stay prepared this summer by keeping an eye on your system and addressing small issues before they turn into big repairs.
