Drainage Unblocking Methods

There are several effective methods to unblock drains, each suited to different types of blockages.

Drainage experts in Surrey A. Lings - Drainage experts in London
Manual Rodding - Drainage Unblocking Method

Manual Rodding

Usually for surface-level blockages.

Manual rodding is often the first step when dealing with straightforward or surface-level blockages. Our engineers use flexible, high-strength drainage rods to manually push or break up obstructions within pipes — ideal for removing build-ups of toilet paper, food waste, or hair.

This is a fast, effective method that doesn’t require machinery or water pressure, making it a cost-effective solution for minor domestic drainage issues.

Best for:

  • Blocked toilets
  • Sinks with food or soap build-up
  • Light blockages close to the surface

HIGH-PRESSURE WATER JETTING

Using specialist high-pressure water jets, we can remove blockages and debris from your pipes.

For more stubborn or deep-seated blockages, we use high-pressure water jetting. This technique uses powerful jets of water to blast through grease, fat deposits, mud, silt, scale, or even minor tree root growth.
Jetting doesn’t just clear the immediate blockage — it also thoroughly cleans the inside of your pipes, helping to prevent future clogs.

Why it works:

  • Fast and highly effective
  • Non-invasive
  • Removes stubborn residue and scale
  • Suitable for domestic and commercial pipework

Common uses:

  • Grease and fat build-up in kitchens
  • Commercial drains
  • Outdoor drains clogged by soil or leaves

CCTV Survey to protect drainage systems in Surrey & London

CCTV SURVEY DRAINAGE

CCTV surveys are a cost-effective and non-invasive way of assessing the health of your drainage systems identifying any potential issues.

When the cause of a blockage isn’t clear — or the same issue keeps coming back — we carry out a CCTV drain inspection. Using a waterproof camera on a flexible cable, we inspect the full length of your underground drainage system in real-time.

This allows us to pinpoint problems like:

  • Pipe damage or collapse
  • Tree root intrusion
  • Misaligned or poorly connected joints
  • Obstructions deep in the system

You’ll also receive a full report and video footage upon request — useful for property purchases, landlord compliance, or insurance claims.

Ideal for:

  • Recurring drainage issues
  • Diagnosing unseen damage
  • Pre-purchase drain checks for new homes

Root Cutting & Pipe Descaling

Effective solutions for removing tree roots and scale build-up in drains.

Over time, tree roots can penetrate drain joints or cracks in underground pipes, especially in older systems. Once inside, they grow rapidly — causing blockages, damage, and even structural collapse.
We use rotating mechanical blades or water-powered root cutters to remove roots without excavation.

Additionally, we offer pipe descaling, which removes mineral build-up and corrosion in cast iron or older metal pipes — restoring smooth flow and extending the life of your system.

Used for:

  • Tree root removal
  • Cast iron pipe maintenance
  • Long-term flow issues

What Causes Blocked Drains?

Blocked drains are more common than most people realise.

Everyday household activities and environmental factors can all contribute to a blockage. Here are some of the most common causes we deal with:

  • Fat, oil and grease from cooking
  • Hair and soap residue in bathroom drains
  • Wet wipes, sanitary products and paper towels
  • Food waste and coffee grounds in kitchen sinks
  • Leaves, silt, and garden debris in outdoor drains
  • Tree root intrusion into underground pipework
  • Structural damage or pipe collapse

 
No matter the cause, our team uses the latest technology to locate and remove the blockage efficiently — and prevent it from coming back.

Common Signs of a Blocked Drain

Not all drain blockages are immediately obvious.

Catching the early warning signs can help you avoid costly damage or disruption:

  • Slow draining sinks or bathtubs
  • Gurgling or bubbling noises from plugholes or toilets
  • Unpleasant smells from drains or manholes
  • Toilets rising too high or not flushing properly
  • Water backing up into sinks, showers or outdoor gullies
  • Flooding or standing water near drains or manholes

Drainage Unblocking Services FAQs

London & South London | A Lings Group Limited

1. What are the most common causes of blocked drains?

The most common causes include a build-up of fat, oil and grease (especially in kitchen sinks), wet wipes and sanitary items being flushed down toilets, and hair and soap scum in bathroom drains. Outdoor drains are often blocked by leaves, mud, and even invasive tree roots. In some cases, old or damaged pipework can collapse or shift, creating recurring blockages.
