These Thanksgiving plumbing tips start with a simple fact about the holiday: few days of the year ask more of a home's drains. A turkey roasts for hours and leaves behind a pan of fat. Potatoes get peeled into the sink. The dishwasher runs three times. Guests shower back to back in the morning and use the downstairs powder room all afternoon. Every one of those things sends water, food or grease into the same set of pipes, often in the same few hours.
Most homes handle it fine. Some do not, and the result is a sink that will not drain, a toilet that overflows, or water coming up through the basement floor drain while the pie is in the oven. This guide covers the habits that keep drains moving on Thanksgiving, what a backup turns into when it goes wrong, and how the ReadiDry Protection Plan handles sewage backup cleanup for homes in Brooklyn, Queens, the Bronx, Westchester and Long Island.
Why Thanksgiving is hard on household drains
A household drain system is sized for normal days. Thanksgiving is not normal. Three things pile up at once.
- Grease. Roasting pans, gravy, butter and fried sides produce more fat than an ordinary dinner, and some of it always ends up rinsed toward the sink.
- Food scraps. Peels, rinds, stuffing and bones get scraped into the sink or the disposal.
- Volume. More people means more flushes, more showers, more hand washing and more dishwasher cycles, all in one day.
Older homes in Brooklyn, Queens and the Bronx often have cast iron drain lines that have narrowed over decades. Many Long Island and Westchester homes have a single main line leaving the house, so a clog anywhere downstream backs up into every fixture above it. The lowest drain in the house, usually the basement floor drain, laundry sink or basement toilet, is where that water shows up first.
Thanksgiving plumbing tips for the kitchen
Keep grease out of every drain
The New York City Department of Environmental Protection warns that pouring cooking oil, poultry fat or grease into the kitchen sink or toilet can cause sewer backups, and that over time grease can build up so much that it clogs pipes completely. Hot fat looks like liquid in the pan, but it cools and hardens inside the pipe.
DEP gives clear steps for home kitchens.
- Let the grease cool, then pour it into a container such as a take out container or an empty carton.
- Label the container "Cooking Oil, Not for Recycling" and put it out with the regular garbage.
- Or put cooled grease in a plastic bag and freeze it before throwing it away.
- Wipe leftover grease off dishes, pots and pans with paper towels before washing them.
Running hot water or dish soap behind the grease does not solve the problem. It only moves the grease farther down the line before it hardens.
Go easy on the garbage disposal
A disposal grinds food, but it does not make food disappear. The ground up material still has to travel through the drain line. On a heavy cooking day, follow a few rules.
- Scrape plates into the trash or a compost bin first. Use the disposal only for small leftover bits.
- Keep potato peels, celery, onion skins, rice, pasta, bones and coffee grounds out of it. These either form a paste or wrap around the blades.
- Run cold water before, during and for several seconds after each use.
- Feed it a little at a time instead of a full sink of scraps at once.
- If it hums but will not spin, turn it off and leave it for later. Never reach into it.
Space out the dishwasher
Run the dishwasher when it is full, but do not start it at the same moment the kitchen sink is draining and someone is in the shower. Spreading big water uses out across the day gives the main line a chance to keep up.
Thanksgiving plumbing tips for bathrooms and guests
Guests do not know your house. They do not know which toilet runs, which one needs a second flush, or where the shutoff valve is. A few minutes of prep before they arrive heads off most bathroom problems.
- Put a plunger next to every toilet guests will use, so a clog gets plunged rather than flushed again.
- Put a small wastebasket in each bathroom so wipes, paper towels and other items go in the trash instead of the toilet.
- Check each toilet's shutoff valve by turning it off and back on, so you know it works if you need it.
- Space out morning showers by 10 or 15 minutes if you have several overnight guests. That helps the water heater and the drains keep up.
- Tell one other adult where the main water shutoff is, in case you are busy in the kitchen when something goes wrong.
If an upstairs toilet does overflow, water can come through the ceiling below within minutes. Our guide on water leaking through the ceiling walks through what to do and when to keep people out of the room.
What a drain backup turns into
A slow kitchen sink is an annoyance. A main line backup is a different event, and it moves through stages.
- Slow drains. Several fixtures drain slowly at once, or the toilet gurgles when the washer drains. That pattern points to a problem in the main line rather than a single fixture.
- Water appears at the lowest drain. Water comes up through the basement floor drain, laundry sink or basement shower when fixtures upstairs are used.
- A full backup. Wastewater spreads across the basement floor, soaking carpet, drywall and anything stored on the slab.
Water from a sewer or drain backup is not clean water. Restoration standards treat it as heavily contaminated, so porous materials it touches, such as carpet, padding and the bottom of drywall, are usually removed rather than dried in place. Our guide to what to do when a finished basement floods covers why sewage backups are handled with stricter rules, and our breakdown of water damage restoration costs in New York explains why that cleanup costs more than a clean water job.
If the drains start backing up on the holiday
- Stop using water everywhere in the house. No flushing, no dishwasher, no showers, no laundry. Every gallon goes to the lowest drain.
- Keep people and pets away from backed up water. Do not walk through it in socks or sneakers.
- Do not pour chemical drain openers into a backed up line. They do not clear main line clogs and they make the water more hazardous for whoever cleans it up.
- Take photos of the water, the drain and anything it has reached.
- Call a plumber or drain company to clear the line, and call for cleanup if wastewater has reached the floor. If you are a ReadiDry member, call the emergency line.
Signs your main line needs attention before the holiday
A week before Thanksgiving is a much better time to call a plumber than the morning of. Watch for these signs now.
- More than one fixture drains slowly at the same time.
- Toilets gurgle or bubble when a sink or the washer drains.
- Water shows up in the basement floor drain or tub when you flush upstairs.
- A sewer smell near basement drains.
- You have had a backup before and never had the line inspected.
A plumber can snake or camera inspect the line and tell you whether roots, grease or a sagging section of pipe is the cause. Some homeowners also ask about a backwater valve, which closes when the municipal sewer surcharges. That is a licensed plumber's job and a separate cost.
How ReadiDry handles sewage backup cleanup
A sewer backup is one of the listed event types in the ReadiDry Protection Plan. When a member calls the 24/7 line, the team confirms the plan is active and explains what to do while the crew is on the way, such as stopping water use in the house. The crew is dispatched ahead of non-member calls, and the member gets a text with the crew lead's name and an arrival window. The line is answered on holidays, including Thanksgiving.
Within the limits in the benefit schedule, what the plan includes for a backup is:
- Emergency extraction of standing water.
- Sewage backup cleanup within plan limits, including removal of contaminated carpet, padding, baseboards and drywall when needed.
- Cleaning and antimicrobial treatment of affected surfaces.
- Air movers and dehumidifiers, set up and monitored for up to 7 days of equipment time per event.
- Hauling away the materials removed during mitigation.
- Daily moisture readings and photo documentation you can share with your insurer.
The plan includes up to 2 covered events per plan year and up to $10,000 of included services per event, at standard published rates. The crew lead confirms what the benefit schedule includes before any work begins.
What the plan does not do
ReadiDry is not insurance. Clearing the clog, snaking or repairing the sewer line and installing a backwater valve are plumbing work and are separate. Rebuilding is separate, including new drywall, flooring and paint. Contents, slow leaks, mold that is already growing and damage that began before the plan became active are not covered. All of it is written in the ReadiDry Plan Terms. Many homeowners policies only respond to sewer backups with an added endorsement, which our guide on whether homeowners insurance covers water damage explains.
The Thanksgiving enrollment deadline
A ReadiDry plan becomes active 14 days after your first payment is confirmed. Thanksgiving is Thursday, November 26. If you enroll today, Monday, November 9, your plan is active on Monday, November 23, three days before the holiday. Enroll after Thursday, November 12, and your plan will not be active in time for Thanksgiving Day.
The ReadiDry plan costs $399 a year or $39 a month, billed through Stripe secure checkout. Your benefit schedule arrives by email within one business day.
Thanksgiving plumbing FAQ
Can I pour turkey grease down the drain with hot water?
No. NYC DEP warns that cooking oil, poultry fat and grease poured into a sink or toilet can cause sewer backups. Hot water only carries the grease farther before it cools and hardens. Let it cool, put it in a labeled container or freeze it in a bag, and throw it away with the regular garbage.
What should never go in the garbage disposal on Thanksgiving?
Potato peels, celery, onion skins, rice, pasta, bones, coffee grounds and grease are the usual troublemakers. Scrape plates into the trash and use the disposal only for small bits, with cold water running.
Why does water come up in my basement drain when I flush upstairs?
That usually means the main drain line is partly blocked, so wastewater backs up to the lowest opening in the house. Stop using water and call a plumber before it turns into a full backup.
Will ReadiDry clear my clogged sewer line?
No. Clearing or repairing the line is a plumber's job and is separate from the plan. ReadiDry handles the cleanup the backup leaves behind, within the benefit schedule limits.
Does the emergency line answer on Thanksgiving Day?
Yes. The ReadiDry line is answered 24 hours a day, 7 days a week, including holidays. Members are dispatched ahead of non-member calls and get a real arrival window on the call.
Is a slow drain covered by the plan?
No. A slow drain is a plumbing issue. The plan covers a sudden sewer or drain backup that puts water in your home after your plan becomes active.
Host with a crew on call
Keep the grease out of the sink, go easy on the disposal, put a plunger by every toilet and know where the shutoff valves are. Then make sure that if the drains lose the battle anyway, the cleanup is already arranged. Enroll by November 12 to be active for Thanksgiving Day.
