    Emergency Drain Unblocking

    A Blocked Drain Can Quickly Become a Much Bigger Problem.

    Blocked drains are inconvenient, unpleasant and, if left unresolved, can lead to wastewater or sewage backing up into a property.

    KD Drainage provides professional drain unblocking for homes, businesses and commercial premises. Our engineers use specialist equipment including high-pressure water jetting and CCTV inspection technology where required to locate and clear blockages safely and efficiently.

    Whether you are dealing with a blocked toilet, sink, shower, waste pipe, overflowing gully, manhole or external drain, we can investigate the problem and work to restore normal flow as quickly as possible.

    If the blockage is caused by something more serious such as tree root ingress, scale build-up, damaged pipework or a collapsed drain, we can identify the issue and advise on the appropriate repair.

    Common Problems We Clear

    From everyday blockages to more serious drainage faults.

    ✓ Blocked drains & waste pipes

    ✓ Blocked toilets, sinks & showers

    ✓ Overflowing manholes & gullies

    ✓ Drain cleaning & jetting

    ✓ Bad odours & recurring problems

    ✓ Commercial drainage blockages

    Clear the Blockage. Then Find Out Why It Happened.

    The first priority is getting your drainage flowing again. Depending on the type and location of the blockage, our engineers may use drain rods, mechanical equipment or high-pressure water jetting.

    But simply clearing a blockage is not always the end of the story. Where problems keep returning, further investigation can identify whether the underlying cause is grease, scale, roots, structural damage or another defect within the pipework.

    That allows us to deal with the immediate emergency while helping reduce the risk of the same problem happening again.

    Signs of a Blocked Drain

    Not Every Blockage Starts With an Overflow.

    Slow-draining water, unusual smells, gurgling sounds and rising water levels can all indicate that a restriction is developing somewhere within the drainage system.

    Getting the problem investigated before the drain becomes completely obstructed can reduce the risk of wastewater backing up into the property.

    Slow drainage

    Sinks, showers or baths taking noticeably longer to empty.

    Bad odours

    Persistent unpleasant smells coming from drains or gullies.

    Gurgling noises

    Unusual sounds when water drains through sinks, baths or toilets.

    Overflowing drains

    Water or waste rising from gullies, manholes or external drainage.

    Why Drains Become Blocked

    Understanding the Cause Helps Stop the Problem Coming Back.

    Drain blockages can be caused by everyday waste entering the system, but recurring problems can also indicate a structural fault further along the pipework.

    Our engineers focus first on restoring flow, then on identifying anything that may make the blockage more likely to return.

    Common causes include:

    ✓ Wet wipes & sanitary products

    ✓ Fats, oils & grease

    ✓ Food & household waste

    ✓ Tree root ingress

    ✓ Scale & silt build-up

    ✓ Lost drain rods or objects

    ✓ Broken or displaced pipes

    ✓ Collapsed drainage

    DIY Drain Unblocking

    Can I Unblock a Drain Myself?

    A very minor blockage close to a sink or plughole may sometimes be resolved with simple cleaning or a plunger.

    However, if water is backing up repeatedly, several fixtures are affected, an external drain is overflowing or you cannot identify the cause, the obstruction may be deeper within the system.

    Professional equipment allows the blockage to be cleared without relying on repeated chemical treatments, while CCTV inspection can identify structural damage, root ingress or more serious defects where required.

    When to Call an Engineer

    Get professional help if…

    ✓ The blockage keeps returning

    ✓ More than one drain or appliance is affected

    ✓ An external drain or manhole is overflowing

    ✓ Sewage or wastewater is backing up

    ✓ There are persistent drainage smells

    ✓ You suspect roots, damaged pipes or a collapse

    As a longstanding Chartered Surveyor, Chartered Building Engineer and former Building Inspector, I would state that this company were the most impressive in all respects relative to the investigation, conclusion, and swift rectification of the failed system at my home. The chaps that attended were extremely professional and unusually very competent in their duties from start to completion. I would recommend them wholeheartedly on projects ongoing.

    Blocked Drain FAQs

    Questions About Blocked Drains.

    How do professionals unblock drains?

    Professional drainage engineers may use drain rods, mechanical cutting equipment, high-pressure water jetting and CCTV cameras. The most appropriate method depends on the type, location and cause of the blockage.

    Will a blocked drain clear itself?

    Occasionally a minor restriction may move, but persistent or recurring blockages usually require attention. Waiting can allow the obstruction to worsen and increase the risk of wastewater backing up.

    How much does it cost to unblock a drain?

    The cost depends on the location and severity of the blockage, the equipment required and whether further investigation or repair is needed. KD Drainage can advise once the problem has been assessed.

    Do I need a CCTV drain survey?

    Not every blockage needs a CCTV survey. It is particularly useful where a blockage keeps returning, is difficult to locate or where damaged pipework, root ingress or a collapse is suspected.

    Should I use chemicals to unblock a drain?

    Chemical products may not remove the underlying obstruction and can be unsuitable for some pipework or fittings. Serious or recurring blockages are better investigated and cleared using appropriate drainage equipment.

    What should I avoid putting down drains?

    Avoid flushing wet wipes, sanitary products and other non-disposable waste. Fats, oils, grease and food waste should also be kept out of drainage wherever possible as they can accumulate and restrict pipework.

    Can tree roots block drains?

    Yes. Tree roots can enter through cracks, displaced joints and defects in underground drainage. Once inside, they can continue growing and trap waste, causing repeated restrictions and blockages.

    Can you help with recurring blocked drains?

    Yes. Once the immediate blockage has been cleared, further investigation can be carried out to identify problems such as root ingress, scale build-up, damaged pipes or partial collapse.
