Thanksgiving Plumbing Tips: Keep Your Seattle Home Running Smoothly This Holiday Season

Hosting Thanksgiving? Here’s how to prevent clogs, protect your pipes, and avoid surprise plumbing emergencies.

Thanksgiving is one of the busiest days of the year for household plumbing — especially here in Greater Seattle, where cold weather, older homes, and heavy kitchen and bathroom traffic all combine to put serious pressure on your drains.

If you’re cooking a big meal, running the dishwasher non-stop, entertaining guests, or juggling back-to-back showers, it only takes one wrong move in the kitchen or bathroom for pipes to clog, drains to slow, or a sewer line to back up.

The good news? A little planning goes a long way.

Here are the best Thanksgiving plumbing tips to keep everything flowing smoothly — and avoid emergency calls during the holiday rush.

1. Kitchen Tips: Prevent the Most Common Thanksgiving Clogs

The kitchen is ground zero for holiday plumbing problems. (We have a dedicated article on what you should never do to pipes — and that includes what you shouldn’t put in them.) Most Thanksgiving drain issues come from what ends up in the sink or garbage disposal — often put there by well-meaning guests.

Follow these simple rules to protect your pipes:

Keep grease OUT of your sink

Grease, fats, and oils solidify inside pipes and are a major cause of sewer backups across Seattle. Instead of pouring grease down the drain, collect it in a can and dispose of it in the trash.

Seattle Public Utilities also offers helpful guidance on proper grease disposal:

Protect your garbage disposal

Your disposal can’t handle most Thanksgiving scraps. Avoid putting these items down the drain:

• Potato peels

• Turkey skin or bones

• Onion peels

• Celery, asparagus, or other fibrous vegetables

• Rice, pasta, or bread (they expand!)

Always run cold water before, during, and after using the disposal to help move residue safely through the line.

If your disposal is already struggling, we’ve written a helpful guide on what not to do:

Give your water pressure a break

Stagger heavy water use (dishwasher, laundry, showers) so your sink drains more efficiently and your guests enjoy better water pressure.

2. Bathroom Tips: Handle Heavy Guest Traffic With Ease

More guests = more bathroom use. Here’s how to prevent backups and keep everything running smoothly:

Set expectations with guests (tactfully)

Encourage your guests not to flush:

• Wipes (even “flushable” ones)

• Paper towels

• Napkins

• Makeup wipes

• Cotton rounds

• Hair

These items are top contributors to holiday clogs and sewer backups across Seattle. And if your toilet starts acting up — won’t stop running or needs to be plunged properly — we’ve got you covered!

Keep hot water flowing

Two quick adjustments help ensure everyone gets a warm shower:

• Bump your water heater temperature slightly (but never above 125°F)

• Space showers at least 10 minutes apart

If your showerhead has low flow, soak it in a bag of vinegar for a few hours to clear mineral buildup before guests arrive.

3. Cold-Weather Tips for Seattle Homes

Thanksgiving typically marks the shift into chilly weather in the Pacific Northwest. Older homes in Ballard, Queen Anne, Magnolia, Fremont, and other Seattle neighborhoods are especially vulnerable to cold-related plumbing issues.

Disconnect outdoor hoses

Left attached, they can freeze, crack, and cause springtime water damage.

Insulate exposed pipes

Pipes in crawl spaces, garages, basements, and attics need extra protection. A frozen pipe can burst and cause major water damage.

Seal drafts near plumbing

Even small cold-air leaks can lead to frozen or sluggish lines.

Thaw pipes safely

If pipes freeze, use a safe heat source like a heat lamp or hair dryer — never open flame.

Thanksgiving Plumbing Do’s & Don’ts

A quick cheat sheet to keep handy:

Why Plumbing Problems Spike During Thanksgiving

Holiday drain issues typically happen because:

• There’s more grease in the kitchen

• More food debris enters garbage disposals

• Showers and hot water tanks are pushed to their limits

• Cold weather slows drain lines

• Older Seattle sewer lines struggle with combined rainfall + increased usage

• Guests flush items that don’t belong in toilets

If there’s already soap buildup, hair, grease, or roots in your drains, Thanksgiving may be the tipping point.
