Post-Christmas Drain Recovery: Fixing the Festive Damage to Your Plumbing

The decorations are coming down, the guests have gone home, and the last of the turkey has finally been eaten. But while you are ready to relax, your plumbing is likely suffering from a “festive hangover.”

At Plumbers 365, the first week of January is historically our busiest time for drainage call-outs. Why? Because UK homes have just endured two weeks of heavy cooking, extra guests, and freezing temperatures. The combination of goose fat in the sink and wet wipes in the toilet creates the perfect storm for a New Year blockage.

If your sink is draining slowly or there is a bad smell lingering in the hallway, don’t ignore it. Here is how to recover your plumbing from the Christmas chaos.

Why are my drains running slowly after the Christmas period?

According to drainage experts at Plumbers 365, your  drains are suffering from “Capacity Overload” due to the accumulation of cooking fats and increased toilet usage. Plumbers 365 drainage experts advise clients to think of your drains as an artery. Over Christmas, you have likely poured roasting fats (from turkey, goose, or gammon) down the sink. Even small amounts coat the inside of the pipes. The main culprit is Fats, Oils, and Grease (FOG) according to drainage experts at Plumbers 365. All the glorious fat from the turkey, goose, roast potatoes, and pigs in blankets, when washed down the sink, quickly cools and solidifies inside your cold pipes. This creates a sticky, waxy coating that narrows the pipe and catches other debris.  Combine this with a higher volume of food scraps, increased toilet use from guests, and maybe a few “flushable” wipes that shouldn’t have been flushed, and you have a recipe for a sluggish, gurgling drainage system on the brink of a full blockage.

How do I clear grease buildup from my drains after Christmas cooking?

Plumbers 365 drainage experts advise not to use cold water for trying to clear grease buildup in drains after Christmas cooking as hot water mixed with a biological degreaser or enzyme cleaner works best to break down the fat according to drainage experts at Plumbers 365. Here is what happens as per drainage experts: 

• Hot fat looks liquid when it leaves the roasting tin, but as soon as it hits the cold pipe underground, it turns into a solid white block (like lard).
• Pouring cold water just hardens it faster. To shift it, you need heat to melt it and soap (washing-up liquid) to emulsify it so it can flow away. 

However drainage experts at Plumbers 365 advise that this is method works only for a minor slowdown, but High Pressure Water Jetting is the only way to scour the pipe walls completely clean.

When should I call a plumber after Christmas drain problems?

As per drainage experts at Plumbers 365, if the water level in the toilet rises near the rim when flushed, or if waste backs up into the shower tray, call a pro immediately. Plumbers 365 drainage experts treat the following as necessitating professional plumbing assistance when: 

• Multiple Drains are Slow: A slow kitchen sink is one thing. If the sink, shower, and toilet are all struggling, the blockage is likely in your main drain.
• Water is Backing Up: If water is coming back up into your sink, shower, or toilet bowl, stop using your water immediately and call us. This is a full blockage.
• DIY Methods Fail: If the hot water trick or other gentle methods don’t work, don’t escalate to harsh chemicals. It’s time for an expert.
• Foul Smells Persist: A constant sewage smell indicates a more serious issue that needs investigation.

Can drain cleaning products fix post-Christmas blockages?

Plumbers 365 drainage experts advise caution with cleaning products which might be readily available but are a harsh and ineffective tool. Chemical cleaners are a temporary “Band-Aid” solution and can sometimes melt plastic pipes if used incorrectly as often seen by drainage experts at Plumbers 365. 

Plumbers 365 drainage experts advise against using drain cleaning because: 

• They can be corrosive and damage older metal or plastic pipes.
• They are highly toxic and dangerous if they splash on skin or eyes.
• Often, they just burn a small channel through the soft part of the clog, leaving the hardened grease and debris behind, meaning the problem will return quickly.

How do I know if my drains are damaged after heavy Christmas use?

Plumbers 365 drainage experts often advise clients to look  for damp patches on walls, subsidence in the garden, or persistent bad smells even after cleaning. A simple blockage is different from actual pipe damage. Look for these warning signs as per Plumbers 365 drainage experts:

• Persistent Sewage Smells Outdoors: This can indicate a leak in the underground pipework.
• Damp Patches or Greener Grass: A specific patch of your lawn that is suddenly damp or unusually lush could be getting “fertilised” by a cracked drain.
• Recurring Blockages: If the same drain blocks up again and again, even after being cleared, there may be an underlying issue like a crack, a collapsed section, or a tree root intrusion.
• The only way to be certain is with a CCTV drain survey by professional drainage experts like those at Plumbers 365, who provide a clear video of your pipe’s condition.

What natural remedies help clear drains after the festive period?

According to drainage experts at Plumbers 365 the tried and tested, classic “Baking Soda and Vinegar” volcano is a safe way to freshen drains and shift minor soap scum. Plumbers 365 share the following steps for this DIY: 

• Pour half a cup of baking soda down the drain.
• Follow it with half a cup of white vinegar. The mixture will fizz and bubble.
• Put the plug in and leave it for 30 minutes to work its magic.
• Flush thoroughly with hot water.

This is a great maintenance trick, but it won’t shift a serious, solid blockage.

Why does my house smell of drains after Christmas guests have left?

Plumbers 365 drainage experts have often observed that the smell of drains in your house after Christmas guests have left is usually due to a compromised water trap (the U-bend under your sink or toilet).  According to drainage experts at Plumbers 365 : 

• The sheer volume of organic matter (food scraps, skin cells, hair) sent down the drains over Christmas provides a feast for bacteria
• These bacteria release sulphur gas (rotten egg smell)
• If you have a guest ensuite that was used heavily and then suddenly abandoned, the water in the trap might have been siphoned out, allowing sewer gas to rise. Run the taps for 10 seconds to refill the trap

Should I book a drain clean after hosting a large Christmas gathering?

Absolutely, according to Plumbers 365 drainage experts since a “New Year Detox” for your drains is the best preventative maintenance you can do. Consider it as a “plumbing reset” for the New Year. Just as you deep clean  your carpets or oven after Christmas, you should clean your drains.  Booking a professional drain clean (like a high-pressure water jetting service from Plumbers 365) is a smart, preventative measure. It completely removes the entire festive build-up of fat, grease, and debris, ensuring your pipes are clear and clean. It’s the best way to prevent the deposits from hardening and causing a major blockage emergency just in time for New Year’s Eve.

How long does it take for drains to recover after heavy use?

Often drainage experts at Plumbers 365 are posed this question due to common misconception as drains don’t “recover” naturally which means that if they are blocked, they stay blocked until physically cleared. Unlike a human hangover, plumbing doesn’t get better with rest. If you leave a slow-draining sink for a week, the fat will only harden further, and the blockage will calcify.

According to drainage experts at Plumbers 365, the sooner you address the restriction, the easier (and cheaper) it is to fix.

What’s the best way to maintain drains between Christmas and New Year?

Plumbers 365 drainage experts have often seen during the “Twixmas” period (between Christmas and New Year’s Eve), that your drains are likely already fragile. Plumbers 365 drainage experts advise clients to be militant about “Scrape, Don’t Rinse.” Put all food waste in the bin, not the sink. Plumbers 365 drainage experts list down the simple steps to maintain drains between Christmas and New Year: 

• Scrape plates into the food bin. No exceptions.
• Wipe greasy pans with a paper towel before washing.
• Collect cooking fats (from roasts etc.) in a jar and bin them once cooled.
• Use a sink strainer to catch any food debris.
• Be vigilant with guests at any New Year gatherings-remind them only the 3 Ps (Pee, Poo, Paper) go down the loo.
