Holiday Septic System Prep: Keeping Your Home Running Smoothly Through Thanksgiving and Brown Thursday
As the holidays roll in, so do the big family gatherings, marathon cooking sessions, and heavy home usage that can put serious stress on a septic system. Thanksgiving and the day after—nicknamed Brown Thursday in the plumbing world for obvious reasons—are two of the busiest days of the year for septic and drain issues.
At Amex Construction, we’ve seen more backed-up kitchens, clogged lines, and overworked tanks during this week than any other. A little preparation on the front end can spare you emergency calls, unpleasant smells, and holiday interruptions.
Why Holiday Weeks Can Overload a Septic System
A septic system is built to handle steady, normal household use. The holidays disrupt that rhythm. Common stress points include:
More people using bathrooms more often
Lots of cooking grease, food scraps, and dishwater hitting the drains
Laundry loads stacking up as guests come and go
Colder weather slowing down natural bacterial activity in the tank
Individually, none of these are catastrophic. Together, they can overwhelm a system fast.
Simple Steps to Protect Your Septic System This Thanksgiving
1. Keep Fats, Oils, and Grease Out of the Sink
Holiday cooking means turkey drippings, gravy, butter, and frying oil. In the drain, these cool and solidify, creating blockages that send wastewater back where you don’t want it.
Best move: collect grease in a container, let it harden, and toss it in the trash.
2. Spread Out Water Usage
Give your septic system breaks to recover.
A few easy habits:
Run the dishwasher late at night rather than during peak bathroom use.
Space out showers by 20–30 minutes.
Avoid back-to-back laundry loads.
Small pauses let the drainfield catch up.
3. Go Easy on the Garbage Disposal
Even with a disposal, septic systems don’t love big chunks of food. Potato peels, bones, rice, and fibrous veggies can clog lines or overload the tank.
When in doubt, scrape into the trash instead of the sink.
4. Use Septic-Safe Products
Choose toilet paper and cleaning products labeled septic-safe. Avoid wipes—even the ones promising they’re flushable. They don’t break down fast enough and cause expensive blockages.
5. Get Ahead With a Pre-Holiday Pump (If Needed)
If it’s been several years since your last pump, the holidays are the worst time to push your luck.
A quick pump-out before family arrives can prevent the classic Thanksgiving septic emergency.
When to Call a Professional
If you notice:
Slow drains throughout the house
Gurgling sounds in pipes
Sewage smells around drains or outdoors
Water pooling over the drainfield
…your system is signaling trouble. These issues rarely fix themselves.
Keep the Holidays Stress-Free
