Knoxville Drain Clogs: Why They Happen More In Winter And How To Prevent Them
When winter arrives in Knoxville, most homeowners focus on staying warm, but few think about how the colder months affect their plumbing. Surprisingly, drain clogs become much more common in East Tennessee during winter, especially around the holidays. At SMK Plumbing and Electric, we see a big rise in service calls from December through February, and many of these issues could be avoided with a little preparation and awareness.
Below, we break down why winter leads to more drain clogs, plus simple ways to keep your plumbing flowing smoothly all season long.
Why Drain Clogs Are More Common In Winter
1. Holiday Cooking and Grease Buildup
With Thanksgiving, Christmas, and New Year’s get-togethers back-to-back, kitchens work overtime. Grease, fats, and oils, like what’s left after cooking bacon, turkey, or roast, solidify quickly in cold pipes. Even if you run hot water, grease eventually cools and sticks to pipe walls, trapping food scraps and causing stubborn clogs.
2. More Guests = More Plumbing Usage
If you’re hosting family or friends, your drains see a lot more action, more showers, more laundry, more toilet flushes, more kitchen cleanup. This extra load can overwhelm older pipes or pipes with existing buildup.
3. Cold Temperatures Slow Down Water Flow
In winter, cold weather cools your pipes and the water inside them, causing certain materials (like soap scum, fats, and oils) to harden faster. When water flows more slowly through colder pipes, debris has more time to settle and create blockages.
4. Outdoor Drains Are Affected by Winter Debris
Leaves, mud, and winter runoff can clog outdoor drains, especially after heavy rain, a common winter occurrence in Knoxville.
How to Prevent Winter Drain Clogs
1. Avoid Pouring Grease Down the Drain
Instead, let grease cool and dispose of it in the trash. You can even pour it into a jar or can for easy cleanup.
2. Use Drain Strainers in Kitchen and Bathroom Sinks
They catch hair, food scraps, and debris before they enter the plumbing system.
3. Run Hot Water After Heavy Sink Use
A short blast of hot water can help flush any grease or soap residue before it solidifies.
4. Be Mindful of What Goes Into the Garbage Disposal
Avoid items like:
-
fibrous vegetables (celery, potato peels)
-
eggshells
-
coffee grounds
-
large food scraps
Winter clogs often start with improper disposal.
5. Space Out Showers When Hosting Guests
This helps maintain water pressure and prevents strain on drains and the water heater.
6. Schedule a Professional Drain Cleaning Before the Holidays
If you’re hosting this season, or your drains have been slow for a while, a preventative drain cleaning can save you from a plumbing emergency at the worst possible time.
When to Call a Professional
If you notice any of the following, it’s time to bring in SMK Plumbing and Electric:
-
Slow or gurgling drains
-
Recurring clogs in the kitchen or bathroom
-
Sewage smells coming from drains
-
Water backing up into sinks or tubs
-
Frequent use of chemical drain cleaners (a sign of underlying issues)
Winter clogs often have deeper causes like buildup in the main sewer line, tree root intrusion, or aging Knoxville plumbing systems, problems that DIY methods can’t fix.
