How to Prepare Your Plumbing Before a Christmas Party (2025 Guide)

Christmas is one of the busiest times of the year for gatherings, cooking, and family celebrations—but it’s also one of the busiest times for plumbers. Between excessive kitchen use, extra bathroom traffic, and winter weather challenges, many homeowners experience leaks, clogs, or emergency backups right during their holiday parties.

Preparing your plumbing system before guests arrive is one of the smartest things a homeowner can do. Whether you're hosting a small family dinner or a large Christmas celebration, this comprehensive guide will help you avoid plumbing disasters and keep everything running smoothly.

Why Pre-Party Plumbing Prep Is Essential

During Christmas gatherings, your plumbing gets pushed harder than usual. Common holiday issues include:

• Clogged kitchen drains from cooking grease and food scraps

• Toilet backups due to increased usage

• Weak water pressure when many fixtures run at once

• Hot water shortages with multiple guests showering

• Garbage disposal jams

• Leaks from old supply lines or worn-out connections

A small unnoticed issue today could turn into a major problem on Christmas Day—with limited emergency plumbers available and premium holiday rates.

That’s why preparing ahead of time protects your home, saves money, and ensures a smooth, stress-free party.

1. Inspect Your Kitchen Plumbing Before Holiday Cooking

The kitchen is the heart of holiday festivities—and the number one source of plumbing emergencies during Christmas.

Clear Slow Drains

If your sink drains slowly now, it won’t survive Christmas cooking.

Slow drainage indicates:

• Grease buildup

• Food debris

• Partial clogs

• Soap scum accumulation

• Under-sink P-trap buildup

A quick professional drain cleaning ensures everything flows smoothly.

Never Pour Grease Down the Drain

Turkey oil, bacon grease, and cooking fats solidify in pipes. Instead:

• Let grease cool

• Scrape into a container

• Toss it in the trash

Prep Your Garbage Disposal

Your disposal must be in good condition before heavy use.

Check for:

• Strange noises

• Weak grinding

• Bad odors

• Water backing up

Run ice cubes and dish soap to freshen it—then run cold water for 20–30 seconds.

Foods to NEVER put in the disposal

• Potato peels

• Eggshells

• Pasta

• Coffee grounds

• Onion skins

• Celery or stringy vegetables

• Turkey bones

These items cause 75% of Christmas disposal clogs.

2. Prepare Your Bathroom Plumbing for Guests

Guest bathrooms experience extra strain during holiday gatherings.

Check Toilets for Weak Flushing

A weak flush indicates:

• Partial clogs

• Worn flapper

• Low water levels

• Mineral buildup

Have slow or gurgling toilets inspected before guests arrive.

Keep a Plunger in Every Bathroom

For hygiene and convenience, place a clean plunger nearby.

Post a Friendly Sign

If hosting a big party, a simple polite sign can prevent problems:

“Please do not flush wipes, paper towels, or hygiene products.”

Most party backups come from misuse—not the plumbing itself.

Inspect Toilet Supply Lines

Old braided hoses crack and burst, especially during cold winter months.

Replace immediately if you notice:

• Rust

• Bulging

• Leaks

• Moisture around connections

3. Check Your Water Heater Before the Party

More guests = more hot water usage.

Flush Sediment

Sediment buildup causes:

• Lukewarm water

• Limited hot water capacity

• Longer heating times

• Higher energy bills

A quick flush or tune-up improves performance instantly.

Adjust the Temperature

Set the water heater to 120°F:

• Hot enough for comfort

• Safe for children and seniors

• Prevents scalding

Consider a Booster or Tankless Upgrade

If your tank is undersized for large gatherings, consider:

• A tank booster

• Recirculation pump

• Tankless water heater upgrade

These provide uninterrupted hot water during the holidays.

4. Inspect Outdoor Plumbing & Winterize

Cold weather in December can cause unexpected issues.

Shut Off and Drain Hose Bibs

Frozen spigots can cause pipe bursts inside walls.

Check Yard Drainage

If rain is expected around Christmas, clear:

• Leaves

• Mud

• Debris

• Mulch

• Blocked grates

Good drainage prevents backyard flooding during your party.

Protect Outdoor Kitchens

If you have:

• Outdoor sink

• Gas line

• Barbecue with water connection

Make sure everything is insulated and leak-free.

5. Test Your Home’s Water Pressure

Multiple guests showering, cooking, and flushing can overwhelm plumbing.

Signs of pressure problems:

• Slow showers

• Weak sink flow

• Toilet refills taking too long

A plumber can test your system, fix restrictions, and adjust the pressure regulator.

6. Do a Whole-House Leak Inspection

Before guests arrive, quickly check:

• Under kitchen sinks

• Behind toilets

• Around water heater

• Under bathroom vanities

• Washing machine hoses

• Refrigerator water line

• Dishwasher connections

Even a small drip can turn into a disaster during heavy holiday usage.

7. Schedule a Professional Drain Cleaning Before the Party

This is one of the best preventative steps for holiday hosting.

A professional plumber can:

• Clear kitchen grease

• Remove bathroom clogs

• Jet out main sewer clogs

• Inspect with a camera

• Ensure no tree root intrusions

This guarantees your drains flow freely during the busiest time of the year.

8. Prepare for Increased Laundry Use

With more guests means more laundry.

Make sure:

• Washer hoses are not cracked

• The drain line isn’t loose

• Drains don’t overflow

• Washing machine cycles run smoothly

Older laundry drains often clog when overloaded during holidays.

9. Have an Emergency Plan—Just in Case

Even with preparation, issues can arise.

Before the party:

• Know where your main water shutoff valve is

• Keep a bucket under sinks with slow leaks

• Have towels and shop vac ready

• Save your plumber’s phone number

A quick response prevents expensive damage.

10. When to Call a Plumber BEFORE Your Christmas Party

Call a professional if you notice:

• Slow draining sinks or tubs

• Gurgling noises from drains

• Sewer smell anywhere

• Toilet bubbling

• Water heater running out fast

• Low water pressure

• Frozen outdoor faucets

• Leaks under sinks or behind walls

These signs often mean bigger issues are developing.
