If you have ever found yourself desperately searching for drain companies near me because your kitchen sink is backing up, you are certainly not alone. Here at Drainage&Plumbing Ltd, we travel across the South East of England handling every type of plumbing emergency imaginable. From minor slow-draining sinks to major underground pipe collapses, we have seen it all. However, every now and then, we encounter a blockage so severe that it even takes an experienced plumber by surprise.
Recently, I was called out to a residential property by a local customer who was dealing with a stubborn, foul-smelling problem. What started as a routine call out for a blocked drain outside kitchen sink turned into a two-and-a-half-hour battle against one of the largest fat blockages I have ever seen in a domestic property. In fact, it was the kind of massive grease build-up that we usually only expect to see in busy commercial restaurant kitchens!
In this week’s blog, I am going to walk you through exactly what happened, how we resolved it safely, and most importantly, the insider tips you need to stop this from happening to your own home.
The Callout: A Stubborn Blocked Drain Outside Kitchen Sink
The customer contacted us needing a blocked drain cleaning service. Her kitchen sink had completely stopped draining, and the exterior drain was overflowing with gray water and a terrible odor.
When I arrived at the property in the South East of England, the customer was understandably stressed. She explained that she lives in a busy, multi-generational household. With her parents living with her, it is a large family that cooks heavily every single day. Furthermore, she admitted that they had not had any professional exterior drain cleaning or maintenance done for a very long time.
Over time, this heavy usage without routine maintenance created the perfect storm for a massive blockage. When a large family is cooking multiple meals a day, the amount of fats, oils, and grease (often referred to in the plumbing industry as FOG) going down the sink can accumulate rapidly.
The Inspection: Finding “Restaurant-Level” Fat
As a premier drain unblocker company, our first step is always to assess the situation thoroughly before deploying any equipment. I started by inspecting the exterior drain that connects directly to the kitchen sink.
As soon as I lifted the drain cover, the root of the problem became immediately obvious. The pipe was completely choked with a colossal blockage. But this wasn’t just a bit of soap scum and food debris; this was a solid, hardened mass of big, white chunks of fat.
When warm grease from roasting pans or frying pans is washed down the sink, it travels as a liquid. However, as soon as it hits the colder underground pipes outside your home, it rapidly cools and solidifies. Over months and years, these big white chunks bind together with other debris, slowly choking the pipe until water can no longer pass through. The sheer volume of fat I found in this domestic drain was staggering—it was genuinely a restaurant-level grease trap situation!
The Professional Solution: Why You Need a Drain Clearing Service
When faced with a solid fat wall like this, store-bought chemical cleaners are completely useless. In fact, pouring harsh chemicals down a completely blocked pipe can cause them to sit and corrode your pipework. This is precisely why calling a professional drain clearing service is always the safest and most effective route.
Deploying the Right Equipment
To tackle this beast, I had to bring out the heavy artillery. Over the course of two and a half hours, I utilized a variety of special drainage tools to break down the solid mass and unblock drain pipe pathways completely.
The primary tool used was a high-pressure drain cleaner (often known as high-pressure water jetting). This sends a powerful, targeted blast of water through the pipes to slice through the hardened fat and flush it away without damaging the pipe itself.
Safety Note: I am often asked by DIY enthusiasts what specific mechanical tools we use to clear these heavy blockages. As a responsible professional, I never list the exact heavy-duty mechanical coring or snaking tools we use. Why? Because these are highly specialized pieces of equipment that require rigorous safety courses and certifications to operate safely. In the hands of an untrained person, these tools can cause severe physical injury or completely shatter underground pipes, leading to thousands of pounds in excavation and repair costs. If you have a severe blockage, do not risk it—always search for drain clearing companies with certified technicians.
The Big Reveal: Shocking the Customer
Once I had successfully broken up the blockage, I didn’t just wash it all away immediately. I actually pulled the massive, big white chunks of fat out of the drain to show the customer exactly what had been causing her grief.
To say she was shocked would be an understatement! She couldn’t believe that all of that had been hiding just beneath her patio. Seeing the physical evidence of the grease build-up was a massive eye-opener for her. It perfectly illustrated why the sink had been draining slowly for weeks before finally giving up completely.
The Final Check: Post-Clearance Camera Inspection
After the two-and-a-half-hour process of removing the fat and jetting the lines, the job wasn’t quite finished. As a trusted drain clog service, Drainage&Plumbing Ltd never relies on guesswork.
To make sure the job was completed properly, I carried out a full inspection using our specialist CCTV drain camera. I fed the camera through the newly cleared pipe and checked the footage carefully with the customer. We could both clearly see that all the fat had been removed. As a result, the pipework looked clean, clear, and as good as new.

To make sure the job was done properly, I used our specialist CCTV drain camera to inspect the pipe after clearing it. I carefully fed the camera through the line and went through the footage with the customer. We could clearly see that all the fat had been removed. The pipe was fully clear and looked as good as new. The water was flowing freely, and the foul smell had completely vanished.
Expert Advice: How to Protect Your Drains from Fat Blockages
Before leaving the property, I sat down with the customer to give her some preventative advice. After all, the best clogged drain cleaning service is the one you don’t need to call very often! Because she has a large family that cooks frequently, I gave her two golden rules to follow to protect her plumbing in the future.
1. The Paper Towel Trick
The best way to prevent fat blocking your drains is to stop it entering the sink altogether. I advised the customer to be careful after cooking heavy meals, like a Sunday roast or a fry-up. Instead of rinsing everything under the tap, it’s always better to wipe off the grease first.
Instead, use a paper towel to wipe away the grease, oil, and fat from the pans while they are still slightly warm. Then, place the used towel straight into the kitchen bin. This simple step makes a big difference. By doing this before washing with hot soapy water, you remove most of the fats that cause serious blockages.
2. The “Big Bucket” Flush (Every 6 Months)
Even if you are incredibly careful, trace amounts of grease will inevitably make their way down your sink. To combat this, I highly recommend a simple maintenance trick: The Big Bucket Flush.
Every six months, fill a large household bucket with water. It does not matter if the water is hot or cold; what matters is the volume and the speed. Pull the plug out of your kitchen sink and pour the entire bucket of water down the plughole as quickly as you safely can.
Why does this work? Underneath your kitchen sink is a U-bend (or P-trap). Its job is to hold a small amount of water to stop sewer gases from coming up into your kitchen. However, heavy debris and small amounts of fat can settle at the bottom of this U-bend. The normal flow from your kitchen tap simply isn’t powerful enough to push it out. By dumping a massive volume of water down the sink all at once, you create a heavy, fast-moving wave that flushes out the U-bend and forces any lingering debris out into the main exterior drain.

Frequently Asked Questions About Kitchen Drain Blockages
Q: How do I fix a severely blocked drain outside my kitchen sink? A: If your exterior drain is completely choked with solid fat or grease, DIY methods like boiling water or baking soda will not be enough to break through the mass. The safest and most effective solution is to call a professional drain clearing service. We use specialized high-pressure water jetting to slice through the solid fat and completely flush the pipe without damaging your plumbing.
Q: Will chemical drain cleaners work on a solid fat blockage? A: We strongly advise against using store-bought chemical cleaners for massive fat blockages. Chemicals often cannot penetrate thick grease logs; instead, they sit on top of the blockage, generating heat that can actually melt or corrode your plastic pipes. For heavy-duty grease removal, it is always best to contact reputable drain cleaning companies rather than risking expensive damage to your pipework.
Q: Who is responsible for exterior drain cleaning: me or the water company? A: In the UK, you are generally responsible for the drains inside your property boundaries (this includes the pipe connecting your kitchen sink to the exterior drain). If the blockage is in a shared sewer pipe that connects multiple properties, it is usually the responsibility of your local water authority. If you are unsure, calling a blocked drain specialist near me can help you diagnose exactly where the blockage is located.
Also…
Q: What are the early warning signs that I need a drain clog service? A: Long before an exterior drain overflows, your plumbing will give you warning signs. Look out for water taking longer than usual to drain out of your kitchen sink, loud gurgling noises coming from the plughole when the washing machine empties, or a damp, foul, rotting smell coming from the drains outside. Catching these early means you can book a routine main drain cleaning before it turns into an emergency.
Q: Can I just pour boiling water down the sink to unblock a drain pipe? A: Pouring a kettle of boiling water down the sink can help melt small, fresh amounts of grease in the U-bend. However, by the time the water reaches the cold exterior underground pipes, it cools down rapidly. It will not melt a solid, established fat blockage further down the line. To completely unblock drain pipe systems safely, mechanical tools and professional jetting are required.
Conclusion: Don’t Wait for the Blockage
This recent job was a perfect reminder of how easily a domestic drain can turn into a major headache. Big families, heavy cooking, and a lack of routine maintenance can quickly lead to big white chunks of fat destroying your pipe’s flow.
If your sink is starting to drain slowly, or if you are noticing a damp, foul smell coming from your exterior drains, do not wait for the water to back up into your kitchen. Take action early. Use the paper towel trick, try the bucket flush, and if all else fails, reach out to the professionals.
