Holiday Season Drain Problems: Why Drains Don’t Take a Break — and Neither Do We

1. Christmas cooking = FOG buildup

FOG (Fats, Oils and Grease) is a winter nightmare.
Hot oil from roasting trays, leftover fat from turkeys, bacon, sausages — when poured down the sink, these cool rapidly in the winter pipes and turn solid.

This creates a thick, waxy layer inside the pipe that catches food debris, eventually blocking the line completely.

2. More guests = More toilet and shower use

Even the most reliable systems get overwhelmed.

• Extra showers

• More toilet flushes

• Bigger loads on already old drainage systems

For older houses in Haywards Heath, Lewes, Burgess Hill, Hassocks, and especially historic properties in Brighton, this can push a fragile system past its limit.

3. Cold weather reveals underlying issues

Tree roots, cracked clay pipes, collapsed sections, and poorly designed gully systems react badly to:

• Freezing temperatures

• Sudden defrosting

• Heavy winter rain

Many customers tell us “It was fine all year until now.”

4. Wet wipes & “flushable” products

When family visits, people tend to use:

• Makeup wipes

• Cleaning wipes

• “Flushable” bathroom wipes

• Cotton buds / sanitary items

None of these actually break down — they cause some of the worst Christmas blockages we see.

Real Holiday Callouts: What We See Every December

Here are just a few examples of typical festive callouts from past years:

Blocked kitchen sinks in Burgess Hill

Large family dinners lead to heavy fat loading.
We’ve had countless calls from Hammonds Ridge, Maple Drive, Leylands and Junction Road after Boxing Day.

Toilets backing up in Haywards Heath

From Muster Green to Bolnore Village, older clay drains combined with guest usage often result in full blockages.

Root blockages in Uckfield and Chailey

Winter rain can cause sudden flow surges, pushing root intrusions into the main line.

Black Swan Drainage Is Active All Holiday Season — No Shutdown

While many trades disappear for 10–14 days over Christmas, we don’t.
That’s because drain emergencies don’t wait for businesses to reopen.

• Christmas Eve

• Christmas Day

• Boxing Day

• New Year’s Eve

• New Year’s Day

• All days in between

This is especially important because many customers don’t want sewage backing up into their home while visitors are staying or while they’re preparing holiday meals.

A Recent Holiday Callout (Example Job Story)

This week in Balcombe, we visited a customer whose shower was draining slowly and whose family bathroom smelled unpleasant — a situation we see a lot around winter.

• The shower trap was full of hair and debris.

• The bath trap had dried up from lack of use, letting sewer smells in.

• After cleaning the trap and refilling the bath with water, the problem was solved in minutes.

Small issues can become big ones quickly during busy holiday periods — which is why it’s better to call early.

Preventing a Holiday Drain Disaster

Here are our top tips to avoid a Christmas emergency:

1. Bin fats, don't pour them

Let fats solidify in the pan, scrape into the bin.

2. Limit what goes into the sink

No gravy, no sauces, no coffee grounds, no peelings.

3. Ask guests not to flush wipes

Put a small bin in the bathroom — it works wonders.

4. Run hot water for 10–20 seconds after dishwashing

Helps keep winter pipework warm enough to prevent solidified grease.

5. If you have an unused bathroom

Run taps weekly to refill traps and prevent sewer smells.

6. Listen for gurgling

If toilets or sinks start making noise, that’s your early warning.

Holiday season (Christmas) FAQs

1. Why do drains block more over Christmas?

The Christmas period puts heavy pressure on household plumbing — more cooking, more guests and colder weather all contribute. Fats, oils and grease (FOG) from festive cooking quickly solidify in winter pipes, causing stubborn blockages. Toilets and showers also get used far more than normal, pushing already strained systems to their limit.

2. Are you available for emergency drain unblocking on Christmas Day?

Yes. We operate 24/7 throughout the entire holiday season, including Christmas Day, Boxing Day, New Year’s Eve and New Year’s Day. If your drains block, overflow or start smelling, we can attend the same day.

3. Do you charge extra for callouts during the holidays?

No — we don’t add festive surcharges. Our pricing is the same as the rest of the year, and during normal hours we never charge call-out fees. Out-of-hours emergency rates remain unchanged.

4. Why does my kitchen sink smell worse in winter?

Cold weather causes fats and grease inside the pipes to harden, trapping food residue and releasing strong odours. Less ventilation in winter also lets smells build up. This is especially common in busy kitchens during December.

5. How can I prevent drain smells in bathrooms I don’t use often?

Unused bathrooms often get dry traps, which let sewer gases enter the room. Run taps weekly, flush toilets, and pour a jug of water into bath or shower traps. This reseals the trap and stops odours — a common issue we see across Mid Sussex in winter.

6. What should I do if my drains overflow during heavy rain?

Stop using water immediately and call a drainage specialist. Winter rainfall can cause hydraulic overload, pushing sewer water back into gardens, gullies and sometimes homes. A rapid response prevents flooding and contamination.
