Common drain blockages in West Sussex

Understanding what causes drain blockages helps you prevent them. Here are the most common issues we deal with across West Sussex:

Fat, oil, and grease blockages

The number one cause of kitchen drain blockages in West Sussex homes. When fat goes down your plughole, it might be liquid, but it solidifies as it cools in your pipes. Over time, this builds up into solid masses that completely block your drains.

West Sussex's thriving food scene, from Chichester's restaurants to seaside fish and chip shops, contributes to the problem. Commercial fat deposits in the public sewer network can cause blockages that back up into private drainage systems.

Prevention tip: Never pour cooking fat down the drain. Let it cool and solidify, then scrape it into your food waste bin.

Wet wipes and sanitary products

Despite what the packaging says, most wet wipes don't break down properly in drainage systems. They catch on rough patches inside pipes, accumulate with other debris, and create stubborn blockages that are difficult to shift.

We remove tonnes of wet wipes from West Sussex drains every year. The county's significant tourist population during summer adds to the burden. Even products labelled "flushable" can cause problems.

Prevention tip: Only flush the three Ps: pee, poo, and paper. Everything else goes in the bin.

Tree root ingress

West Sussex has extensive tree coverage, from the woodlands of the High Weald to the mature gardens in established towns. Those trees need water, and when their roots detect moisture escaping from drain joints, they grow towards it. Over time, they can penetrate drainage pipes, causing blockages and structural damage.

This is particularly common in the rural areas, the South Downs villages, and anywhere with mature trees near drainage runs.

Prevention tip: If you have large trees near your property, consider a CCTV drain survey every few years to catch root intrusion early.

Coastal and groundwater challenges

Properties along West Sussex's coast face specific drainage challenges. High water tables, particularly in low-lying areas like Selsey, can affect drainage capacity. Coastal erosion has also affected infrastructure in some areas.

Sandy and clay soils along the coastal plain can shift and settle, affecting pipe alignment over time.

Chalk and clay geology

The South Downs are chalk, while the Weald to the north is clay. Each creates different drainage challenges:

• Chalk areas create hard water that can cause mineral buildup in pipes
• Clay areas expand when wet and contract when dry, stressing pipe joints
• Coastal plain has mixed geology with specific drainage characteristics

Collapsed or damaged pipes

West Sussex has properties ranging from brand new to several centuries old. Older properties often have clay or cast iron drainage pipes that deteriorate over time. Ground movement, tree roots, heavy vehicle traffic, and simple age can cause pipes to crack, collapse, or become misaligned.

When a pipe collapses, debris accumulates at the collapse point, creating a blockage. The solution isn't just clearing the blockage but repairing or replacing the damaged section.

Foreign objects

Children's toys, mobile phones, jewellery, excessive toilet paper, and countless other items end up in drains. Sometimes it's accidental, sometimes it's curiosity (parents of toddlers, you know what we mean), and sometimes we never do find out how a full-size action figure got into an outside drain.

Whatever's causing your blockage, we have the equipment and expertise to remove it and get your drains flowing freely again.

Our drain unblocking methods

Different blockages require different approaches. We arrive equipped to deal with whatever we find:

High-pressure water jetting

Our primary tool for most blockages. High-pressure water jetting uses specialised nozzles to blast water at pressures up to 4,000 PSI through your drains. This breaks up blockages, scours the pipe walls clean, and flushes debris through to the main sewer.

Jetting is highly effective against fat and grease buildups, accumulated debris, and light root intrusion. It's also the best way to clean drains preventatively, removing buildup before it becomes a full blockage.

Mechanical drain cleaning

For blockages that won't shift with water alone, we use mechanical cleaning equipment. Rotating cutting heads can break through solid blockages, cut through root masses, and clear compacted debris.

We match the cutting head to the pipe size and blockage type, ensuring effective cleaning without damaging your drainage system.

CCTV drain surveys

When we need to see exactly what's happening inside your drains, we deploy our CCTV survey equipment. Waterproof cameras travel through your drainage system, sending back real-time footage that shows us the blockage location, its cause, and the overall condition of your pipes.

CCTV surveys are essential for diagnosing complex blockages, locating collapsed pipes, and planning repair work. We provide you with the footage and a detailed report of our findings.

Manual rodding

Sometimes the traditional approach is the best one. Manual drain rods are effective for clearing straightforward blockages in accessible drain runs. They're quick to deploy and often all that's needed for simple blockages close to access points.

Drain unblocking for West Sussex businesses

Commercial drain blockages can disrupt your operations, drive away customers, and create health and safety issues. We provide rapid commercial drain unblocking services to businesses across West Sussex.

Tourism and hospitality

West Sussex's coast and countryside attract millions of visitors annually. Hotels, guest houses, and holiday parks rely on functioning drainage.

From Bognor Regis beachfront hotels to South Downs country house hotels, we provide rapid response to keep hospitality businesses running smoothly.

Restaurants and food service

West Sussex's food scene ranges from Michelin-starred restaurants to seaside cafes. Kitchen drains face heavy demands and are prone to fat and grease blockages.

We keep commercial kitchens draining properly, with both emergency callouts and scheduled maintenance to prevent problems before they happen.

Retail and commercial premises

Blocked toilets in retail premises create customer complaints and can force you to close facilities. We respond quickly to commercial blockages across West Sussex's shopping centres, high streets, and retail parks.

Gatwick Airport businesses

The airport and its surrounding business parks have specific drainage requirements. We work with facilities managers across the Gatwick area to maintain commercial drainage.

Care homes and retirement facilities

West Sussex's popularity as a retirement destination means many care homes and retirement complexes. We understand the need for rapid response and minimal disruption in these settings.

Schools and educational facilities

From independent schools like Christ's Hospital and Lancing College to state schools across the county, we work with estates teams to maintain drainage in educational buildings.

Property management

If you manage multiple properties across West Sussex, you need a reliable drainage contractor you can call whenever tenants report problems. We work with property managers and letting agents across the county, providing consistent service whether the call is for a flat in Worthing or a cottage in Petworth.

Emergency drain unblocking in West Sussex

Some blockages can't wait until morning. Sewage backing up through your toilet, drains overflowing into your garden, or water flooding your kitchen floor all require immediate attention.

Our 24/7 emergency service means you're never left waiting with a drainage crisis. Call us any time, day or night, and we'll dispatch an engineer immediately.

What counts as a drainage emergency?

You should call our emergency line if you're experiencing:

• Sewage backing up into your property
• Drains overflowing and flooding outdoor areas
• Complete blockage of your only toilet
• Foul smells from drains inside your property
• Multiple fixtures affected (suggesting a main drain blockage)
• Any drainage issue creating a health hazard

What to do while you wait

If you've called us for an emergency and you're waiting for our engineer to arrive:

1. Stop using water - Don't flush toilets, run taps, or use appliances that drain water. Every bit of water you add makes the problem worse.
2. Protect your property - If water is escaping, move valuable items out of the way. Put down towels or use a wet vacuum if you have one.
3. Ventilate the area - If there are foul smells, open windows and doors to improve ventilation. Avoid spending extended time in affected areas.
4. Don't try chemical drain cleaners - These are rarely effective on serious blockages and can be dangerous for our engineers to work around.
5. Locate your outside drain - If you can safely identify and access your outside drain, this helps our engineer get started faster when they arrive.

Preventing drain blockages

The best blockage is one that never happens. Here's how to keep your West Sussex property's drains flowing freely:

In the kitchen

• Never pour fat or oil down the drain - Let it cool and dispose of it in your food waste bin
• Scrape plates thoroughly - Food debris should go in the bin, not down the sink
• Use sink strainers - Catch food particles before they enter your drains
• Run hot water after washing up - This helps flush grease through the system
• Clean your waste disposal regularly - If you have one, keep it clean and avoid overloading it

In the bathroom

• Only flush the three Ps - Pee, poo, and (toilet) paper. Nothing else.
• Use drain covers - Catch hair before it enters your drains
• Clean pop-up stoppers regularly - Hair and soap scum accumulate on these
• Avoid excessive bath products - Some can contribute to buildup in pipes

Outside

• Keep drain covers clear - Remove leaves, debris, and any obstructions
• Don't plant trees too close to drains - Roots can travel considerable distances to find water
• Know where your drains are - Don't build over them or block access
• Consider periodic maintenance - Annual jetting can prevent buildup becoming blockages

For coastal properties

• Monitor for corrosion - Salt air can accelerate deterioration of metal components
• Check after storms - Heavy weather can affect coastal drainage
• Be aware of water table - Low-lying coastal areas may have drainage affected by groundwater

CCTV drain surveys in West Sussex

Sometimes you need to see what's happening inside your drains. Our CCTV drain survey service provides exactly that, using specialist cameras to inspect your drainage system from the inside.

When you might need a CCTV survey

• Buying a property - A pre-purchase drain survey can reveal problems before they become yours
• Recurring blockages - If you keep getting blocked, there's usually an underlying reason
• Planning extensions - You need to know where drains run before building over them
• After a blockage - To check for damage and confirm the drain is fully clear
• Insurance claims - Evidence of drain condition for insurance purposes
• Selling a property - Demonstrate good drainage condition to buyers

What you get

Our CCTV surveys include:

• Full inspection of accessible drainage runs
• Real-time footage reviewed with you on-site
• Written report detailing findings
• Recommendations for any repairs needed
• Digital copy of the footage for your records

Survey pricing

• Homebuyer survey: From £195
• Full property survey with report: From £245
• Commercial surveys: Priced based on system size

Drain repairs in West Sussex

When clearing a blockage isn't enough, we provide full drain repair services across West Sussex. Our repair capabilities include:

Patch lining

For localised damage like cracks, small holes, or joint failures, patch lining provides a repair without excavation. We install a resin-impregnated patch that bonds to the inside of the pipe, sealing the damage and restoring structural integrity.

Drain relining

When a longer section of pipe is damaged, drain relining (also called cured-in-place pipe or CIPP) creates a new pipe within the old one. A flexible liner saturated with resin is pulled through the damaged pipe, inflated against the pipe walls, and cured in place. The result is a seamless, jointless new pipe without the need for excavation.

This is particularly valuable in historic towns like Arundel and Chichester, where excavation can be disruptive and expensive.

Excavation and replacement

Some damage requires traditional excavation and pipe replacement. If a pipe has completely collapsed, been severely displaced, or is beyond repair, we'll excavate, remove the damaged section, and install new pipework.

We always explore no-dig options first, but when excavation is necessary, we do it properly. We handle everything from small domestic repairs to major drain reconstruction projects.

Why West Sussex properties develop drainage problems

Understanding why drains block helps you prevent problems. Here's what makes West Sussex properties susceptible to drainage issues:

Age and variety of housing stock

West Sussex's housing ranges from medieval buildings in towns like Arundel to brand-new developments across the county. This means drainage systems of every age and type:

• Historic towns like Chichester, Arundel, and Petworth have drainage that's been modified over centuries.
• Victorian seaside resorts like Worthing and Bognor Regis have period drainage serving densely built areas.
• Post-war new towns like Crawley have more consistent but now ageing drainage.
• Modern developments are expanding across the county, with new infrastructure but sometimes rushed installation.

Geological factors

West Sussex's geology varies significantly:

• South Downs chalk creates hard water that can cause mineral buildup
• Wealden clay expands and contracts with moisture, stressing pipes
• Coastal plain has mixed geology with sand, gravel, and clay
• River valleys have alluvial deposits that can shift

Coastal influences

The county's extensive coastline creates specific challenges:

• High water tables in low-lying areas
• Salt air accelerating corrosion
• Storm damage to coastal infrastructure
• Coastal erosion affecting some areas

Tourism and seasonal population

West Sussex's seaside resorts see significant seasonal variation in population. This puts pressure on drainage infrastructure during peak summer months and creates maintenance challenges.

Frequently asked questions

How quickly can you get to me?

For most areas of West Sussex, we can reach you within 60 minutes. Chichester, Crawley, Worthing, Horsham, Bognor Regis, and Haywards Heath typically see response times of 30-45 minutes. More rural areas of the South Downs and Weald may take slightly longer.

Do you charge a callout fee?

No. We don't charge for turning up. You only pay for the work we actually do.

Can you unblock drains at night?

Yes. We operate a genuine 24/7 service. Whether you call at 2pm or 2am, we'll have an engineer on the way.

What if you can't clear the blockage?

It's rare, but occasionally we encounter blockages that can't be cleared (usually due to collapsed pipes). In these cases, you don't pay for unsuccessful work. We'll explain what we've found, provide a CCTV survey of the problem, and quote for the repair work needed.

Do I need to be home?

For inside blockages, yes. For outside drains that are accessible without entering your property, we can sometimes attend while you're out, though we prefer to show you what we've found and explain the work.

How do I know if the blockage is my responsibility?

Generally, drains within your property boundary are your responsibility. The public sewer (usually under the road or shared between multiple properties) is the water company's responsibility. In West Sussex, this is Southern Water. If you're unsure, we can help you determine where the problem lies.

Can you help with drains that smell but aren't blocked?

Yes. Drain smells often indicate partial blockages, dried-out traps, or ventilation problems. We can diagnose and resolve most smell issues.

Do you do CCTV surveys without unblocking work?

Absolutely. We provide standalone CCTV surveys for homebuyers, property sellers, landlords, and anyone who wants to know the condition of their drains.

What areas of West Sussex do you cover?

All of it. We serve every part of West Sussex, from East Grinstead in the north to Selsey in the south, from Chichester in the west to Shoreham in the east, and everywhere in between.

Are you insured?

Yes. We carry full public liability insurance and employer's liability insurance. We're happy to provide certificates on request.

Do you offer guarantees?

We provide a 30-day guarantee on all unblocking work. If the same blockage returns within 30 days, we'll clear it again at no charge.

Can you deal with shared drains?

Yes. Shared drains serving multiple properties can be complicated, but we deal with them regularly. We can help you identify who's responsible for what and coordinate with neighbours if needed.

Do you work in the South Downs National Park?

Yes. We serve properties throughout the South Downs National Park and understand any specific requirements for working in protected landscapes.
