Quick answer (November 2026)
The day after Thanksgiving is the plumber’s busiest day of the year. Roto-Rooter says “Brown Friday” consistently brings a 50% spike in service calls, and calls run about 21% higher across the Thursday-through-Sunday holiday weekend. In 2026, Thanksgiving is November 26, so Brown Friday is November 27.
- What breaks: kitchen drains, garbage disposals, toilets, and main lines under the weight of a full house.
- What wins the weekend: staffing set early, trucks stocked for drain work, tight triage at intake, and getting the closest qualified tech moving fast.
- Don’t forget: if you run Google Local Services Ads, missed calls during your listed hours are now billable.

Every plumber knows the pattern. Thanksgiving Day is quiet. Then Friday morning, the phones light up: disposals jammed with potato peels, kitchen sinks backed up with turkey grease, toilets overflowing in houses that had twelve guests and one bathroom.
Roto-Rooter calls it Brown Friday, and its numbers back up what every plumber already knows: the day after Thanksgiving brings a 50% spike in service calls. Here’s how to be ready for it, a week out.
Why Brown Friday happens
Roto-Rooter puts it down to “homes full of guests, extra showers, and marathon kitchen sessions,” plus “greasy turkey drippings and food scraps.” In plain terms:
- Grease and fat poured down the sink go solid in the pipes.
- Starchy and fibrous food in the disposal: potato peels, celery, onion skins.
- More people, more flushing. Guest bathrooms get used far more than usual, along with more wipes and paper.
- Extra showers and laundry push already-slow drains and older main lines past their limit.
- The problems surface Friday because people put up with a slow drain on Thursday and call once guests are gone or the sink won’t drain at all.
The calls you’ll get
| Call | Usual cause | Who to send |
|---|---|---|
| Kitchen sink backed up | Grease and food in the line | Any drain tech with a cable machine |
| Garbage disposal jammed or humming | Peels, bones, fibrous scraps | Any tech; carry spare disposals |
| Toilet clogged or overflowing | Overuse, wipes, paper | Any tech |
| Multiple drains backing up, sewage in a tub or floor drain | Main line blockage | Tech with a main-line machine, ideally a camera and jetter |
| No hot water | Water heater pushed by extra showers and laundry | Tech who does water heaters |
Staffing: set it now
- Decide who’s on Thursday night through Sunday, and tell them this week, not Wednesday.
- Put your main-line specialists on Friday. Sewer backups are the most urgent and the most profitable calls of the weekend.
- Staff the phones. The busiest day of your year is a bad day to send calls to voicemail.
- Be clear about holiday pay and on-call rules before the weekend. See holiday on-call schedules and pay.
- Plan for fatigue. A tech who ran 11 calls Friday shouldn’t be first up Saturday at 6 a.m.
Stock the trucks
Triage at intake
When the board is overloaded, the order matters. A few questions on the call sort it out:
- Is sewage or water coming up anywhere? Floor drain, tub, or overflowing toilet means it goes first.
- Is it one drain or several? Several means a main line, and it needs the right tech and equipment.
- Is there a working bathroom in the house? No working toilet is more urgent than one clogged out of three.
- Can it wait until Monday? A slow bathroom sink can, and many customers are fine with that if you offer a real time.
Write down the answers on the job, so the tech arrives knowing what he’s walking into. For the phone side, see how to handle the booking call.
Dispatching the rush
- Closest qualified tech wins. On a day with three times the calls, drive time is what kills your capacity.
- Main-line jobs only go to main-line techs. Sending a tech without the right machine to a sewer backup costs a second truck roll.
- Keep Monday visible. Non-urgent calls you push to Monday should be booked into a real slot, not a sticky note.
- Photos on every job. Grease clogs, roots, and wipes in the camera footage are worth showing the customer, and worth keeping in case of a dispute.

Answer every call (it costs you now)
If you advertise on Google Local Services Ads, there’s a new reason to answer. Since October 1, 2026, a missed call during your listed business hours is billed as a lead if the caller stays on the line for more than 20 seconds. On a holiday weekend with a skeleton crew, that adds up fast.
- Match your listed hours to the hours someone will actually pick up over the holiday.
- Use an answering service if your office is closed but your techs are working.
- Call back within minutes, not hours. That caller is dialing the next plumber.

Get ahead of it with customers
A short email, text, or social post to past customers the week of Thanksgiving does two things: it prevents some clogs, and it puts your number in front of them right before they need it. Simple tips like these make good material:
Share with your customers: Don’t pour grease or fat down the drain. Let it cool and throw it in the trash. Keep starchy and fibrous scraps like potato peels out of the disposal. Run cold water when the disposal is on. Don’t flush wipes, even “flushable” ones. Space out showers so the water heater can recover. And save our number, just in case.
After the weekend
- Ask every Brown Friday customer for a review while they’re still relieved.
- Follow up on main-line jobs. A sewer line that backed up once will likely do it again. Camera footage is a natural lead-in to a repair or replacement estimate.
- Check the numbers: calls taken, calls missed, jobs booked, and how many went to Monday. Use them to staff next year.
- Thank the crew. They just worked the hardest day of the year on a holiday weekend.
