A blocked drain isn’t just an inconvenience—it’s a ticking clock. The quicker you act, the less disruption, damage, and expense you’ll face. Let our expert team help you maintain precise, safe, and efficient drainage systems.
1. Slow Draining Water
One of the most common signs of a blocked drain is water draining slowly from sinks, baths, or showers. This often indicates a partial blockage in your pipes.
Why It Happens: Over time, debris such as hair, soap scum, grease, and food particles can accumulate in your pipes, restricting water flow and eventually leading to more severe blockages.
What To Do: Avoid using harsh chemical drain cleaners, as they can corrode pipes and worsen the problem. Instead, try using a plunger, drain snake, or other mechanical tools to remove the obstruction. If the issue persists, it’s time to contact a professional plumber.
Tip: Regular maintenance, such as clearing hair traps and avoiding pouring grease down the sink, can help prevent slow-draining pipes.
2. Gurgling Sounds
If you hear gurgling noises coming from your drains, it’s a warning sign that air is trapped in your pipes due to a blockage.
Why It Happens: Blockages prevent water from flowing freely, causing air to become trapped and produce bubbling or gurgling sounds. This is often noticeable when using multiple drains at once.
What To Do: While minor blockages might be cleared with a plunger, persistent gurgling usually requires professional attention. Our team at Maintracts Services Ltd can perform a CCTV drain survey to pinpoint the problem and provide a reliable solution.
Tip: Ignoring gurgling sounds can lead to more severe blockages and water damage.
3. Foul Odours
Unpleasant smells coming from your drains are a clear indication that waste and organic material are trapped.
Why It Happens: When blockages trap food, grease, and other debris, bacteria can build up, causing intense, unpleasant odours.
What to Do: Simple preventive steps, such as regularly cleaning your sink strainers and running hot water through your pipes, can help reduce odours. Persistent smells, however, often signal a deeper blockage, which professionals should address.
Tip: Smelly drains are a classic warning sign of a blocked drain that homeowners shouldn’t ignore.
4. Water Backing Up
Water backing up into sinks, baths, or toilets is one of the most serious warning signs of a blocked drain.
Why It Happens: A complete blockage further down the drain line prevents water from exiting, forcing it to flow back into your home.
What To Do: This is an urgent issue. Turn off any water sources and contact a professional immediately to prevent flooding and damage. At Maintracts Services Ltd, we provide emergency plumbing and drainage services across London to resolve such issues efficiently.
Tip: Avoid using the affected drains until a professional has assessed the problem.
5. Overflowing Drains
Water overflowing from outdoor drains, gully traps, or drain covers—especially during heavy rain—indicates a blockage in external drainage.
Why It Happens: Leaves, garden debris, and soil can accumulate in outdoor pipes and drains, reducing their capacity to handle rainfall.
What To Do: Regularly clear external drains of debris. If overflow occurs despite this, it’s best to call a professional to inspect and clear the blockage. At Maintracts, we offer high-pressure drain jetting and drain cleaning services for both residential and commercial properties.
Tip: Schedule annual drain maintenance to prevent outdoor flooding.
6. Multiple Drains Affected
When more than one drain in your property is slow or backing up, the problem usually lies in the main sewer line.
Why It Happens: Blockages in the main sewer line affect all connected drains, from kitchen sinks to bathroom toilets.
What To Do: This is a serious issue that requires professional inspection and attention. Our CCTV drain surveys help identify blockages quickly and accurately, allowing for effective repairs.
Tip: Early detection prevents extensive damage and costly repairs later on.
7. Visible Blockages
Sometimes, a blocked drain is obvious—standing water, debris around drain covers, or exposed pipes in your garden can indicate a blockage.
Why It Happens: Debris and leaves can physically block the flow of water in visible parts of the drainage system.
What To Do: Keep gutters, drain covers, and gully traps clear of debris. If water continues to back up, our expert drainage team can clear the blockage and prevent future issues from occurring.
