High-Pressure Water Jetting

When it comes to clearing drains, we nearly always go for water jetting, it just gets the job done. It’s quick, strong, and sorts out most of the regular issues. With jetting gear, we send pressure down the pipe and blast away grease, old food, hair, and whatever else has built up. It’s even strong enough to take on bigger clogs, much stronger than using rods for the hard jobs.

CCTV Drain Surveys in Seven Sisters

When a blockage isn’t straightforward or difficult to diagnose, a CCTV drain survey provides a precise internal view of your pipes. Rather than relying on digging or assumptions, we deploy high-definition cameras that navigate through the pipes, delivering real-time video to our engineers. This process allows us to spot issues such as cracks, structural failure, root ingress, or excess residue. With this visual insight, we can locate the true source of the problem and determine the right course of action.

Signs You Have a Blocked Drain

Not all drainage issues shout for attention. Many start with minor hints that can lead to more costly repairs if ignored. Here are some of the most common things to look for to keep an eye on, whether you’re at home or running a business.

Water Draining Slowly

Slow drainage in common household drains is often the earliest indication of a forming blockage within your plumbing system. In kitchens, the culprit is frequently buildup from grease and scraps, while in bathrooms, it’s typically blockage from hair, soap, and scale. If water is sitting, it’s a clear sign the system should be checked.

Unblocked Sink

Unpleasant Smells

Persistent foul odours coming from your drains are a strong signal that organic matter, such as food particles, fats, or sewage, is getting trapped where it shouldn’t. These substances can become lodged in your drains and begin to decompose, releasing nasty gases. If you smell these odours near your sink, shower, or external drainage, it’s likely that a blockage is already taking shape and should be sorted quickly.

Gurgling Sounds From Pipes

Unusual sounds coming from your drains, particularly low bubbling sounds, are often a sign that air pockets are forming. This typically occurs when water is struggling to move past a blockage, causing air to be drawn in behind it. If your pipes begin making noises reminiscent of a kettle, it’s recommended to have them checked by a specialist.

what causes blocked drains

Water Backing Up

Water backing up instead of draining? That’s one of the obvious signs. A blocked drain is likely the cause. And trust me, if you’ve seen it once, it won’t fix itself. Call us in, and we’ll make sure it’s cleared quick.

Toilet Flushing Poorly

A toilet that struggles to clear waste or refills unusually slowly may indicate a clog within the main toilet pipe. These obstructions are often the result of inappropriate materials being flushed, common culprits include flushable wipes, feminine hygiene items, or large amounts of paper.

Overflowing Outdoor Drains

If you observe water emerging from external drains during or after rainfall, the issue may be more serious than simple surface runoff. A significant underground blockage could be stopping water from flowing, causing water to back up. Left untreated, this overflow can damage gardens, driveways, and even the structural foundations of your property. Prompt attention is essential to prevent further complications.

Multiple Fixtures Affected at Once

If more than one thing’s draining slowly, like your toilet, sink, and bath all playing up together, it’s probably not just a small clog. When it’s in the main drain, the whole system gets hit. A quick go with a plunger won’t do the trick here. You’ll probably need a pro to inspect things with a camera and clear it with pressure to get things moving again.

Damp Patches or Mould

Sometimes it starts with a hint of something off. A faint odour near the cupboard. A dark patch spreading in a corner. Maybe even a strange growth. These quiet warnings often mean something hidden, a leak or blockage, hiding underfoot, slowly coming to light.

    Garden sorted, no more flooding.

    Cheers to Clark Drainage for getting our garden sorted after that downpour. Great job. We’d tried a few things ourselves with no luck, but they came in, identified the issue quickly, and had the drainage working perfectly again.

    It’s not glamorous work but they do it with a smile and real pride. Can’t say I’ve ever seen someone so happy clearing a drain, but they made the whole thing stress-free and even a bit fun.
