Signs Your Drain is Blocked

⚠️

Water backing up from multiple outlets

If your kitchen sink, shower, and toilet all start draining slowly at the same time, the main drain line is blocked. This is common in Portsmouth's older terraced properties where multiple waste pipes connect to a single Victorian clay drain.

⚠️

Gurgling sounds when water drains

A gurgling toilet when you run the bath tap means air is trapped by a blockage downstream. The sound occurs when water displacement forces air back through the system. It's often the first sign before complete blockage occurs.

⚠️

Bad smells from drains or outside gullies

Sewage odours indicate waste water is sitting stagnant rather than flowing freely. In Portsmouth's coastal climate, the smell becomes more noticeable during warm weather when bacteria multiply faster in standing water.

⚠️

Overflowing manholes in your garden

When manholes start filling up with water and waste, the blockage is severe and downstream from that point. Many Southsea properties have shared drainage systems, so the blockage might affect neighbouring properties too.

Common Blockage Causes in Portsmouth Properties

Tree roots in Victorian clay pipes

Many streets around Old Portsmouth still have original clay drainage pipes from the 1800s. Tree roots penetrate joints seeking water, then grow thick enough to completely block the pipe. Plane trees along roads like Albert Road are particularly aggressive.

Grease and fat buildup

Cooking oils solidify in pipes, especially during Portsmouth's colder months when soil temperatures drop below 10°C. The fat layer catches other debris until the pipe blocks completely. This affects kitchen waste pipes most commonly.

Wet wipes and sanitary products

Despite being marked 'flushable', wet wipes don't break down like toilet paper. They catch on rough pipe joints and create blockages that trap other waste. Even baby wipes cause serious problems in drainage systems.

Storm water overwhelming combined drains

Many Portsmouth properties have combined foul and surface water drainage. During heavy rainfall, especially around Portsea Island's low-lying areas, the system can't cope and sewage backs up into properties through floor drains.

How We Clear Different Types of Blockages

1

High-pressure water jetting

We use specialist jetting equipment that fires water at up to 4000 PSI through the blockage. The high-pressure head cuts through grease, breaks up debris, and flushes tree roots. This method works on pipes from 100mm to 300mm diameter.

2

Electro-mechanical cleaning

For solid blockages like compacted wet wipes or heavy grease buildup, we use rotating cutting heads that physically break up the obstruction. The spiral cutting action is particularly effective on root masses in older clay pipes.

3

CCTV drain surveys before and after

We insert a waterproof camera to identify the exact blockage location and type before choosing the clearing method. After clearance, we survey again to confirm the pipe is fully clear and check for damage that might cause future problems.

4

Manhole pump-out for severe blockages

When manholes are overflowing with sewage, we first pump out the standing waste water using our tanker vehicle. This reveals the blockage point and prevents contaminated water spreading across your property during clearance work.

When to Call for Emergency Drain Clearance

Sewage backing up into your property

If waste water starts coming up through floor drains, shower traps, or toilet bases, stop using all water immediately and call for emergency clearance. This creates serious health hazards and can damage floors and furnishings quickly.

Multiple properties affected on your street

When neighbours also report drainage problems, the blockage is likely in the main sewer under the road. Portsmouth City Council is responsible for public sewers, but private drainage connecting to them still needs professional clearance.

Complete drainage failure during bad weather

Portsmouth's coastal location means heavy rainfall can overwhelm drainage systems quickly. If your drains stop working completely during storms, emergency clearance prevents sewage flooding your property.

Foul odours that won't clear after 24 hours

Persistent sewage smells indicate waste is backing up somewhere in your system. The longer it sits, the worse the smell becomes and the higher the risk of harmful bacteria developing in standing water.
