CCTV drain surveys in Bristol

Most drain problems are hidden underground. You see a slow sink or a full chamber, but not why. A CCTV drain survey answers that question. A camera on a flexible rod goes into the drain from an inspection chamber and films the inside of the pipe. The engineer watches on a screen, records it and notes the distance to each problem.

In Bristol, this is particularly useful for older homes. Redland, Cotham, Clifton and Bishopston have many large Victorian villas and terraces with clay drains laid well over a century ago. Mature trees are common in front and back gardens. Our Redland area page explains the housing and drainage common in BS6.

When a survey is worth it

Situation	Why a camera helps
Same drain blocks again and again	Shows if there is a crack, dip, root or collapse causing it
Buying an older house	Finds faults before you commit, so you can negotiate or plan
Damp or subsidence near a drain run	Checks whether a leaking drain is washing out soil
Planning an extension over a drain	Shows the route and condition before building over it
Smell with no obvious cause	Finds broken joints or a missing section
Rats in the garden or under the floor	Finds open joints or old disused pipes rats can use

If your drain has just blocked once after a lot of wipes, you probably do not need a survey. Clear it and see if it stays clear. Our blocked drains page covers clearance.

What the camera often finds under Bristol homes

Tree roots. Roots look for water. Old clay pipes have joints every metre or so, and those joints were often sealed with mortar or nothing at all. Fine roots get in, grow and catch paper. Big gardens in Redland and Henleaze with mature trees see this a lot.

Displaced joints. Ground movement shifts one section of pipe against the next. Waste catches on the lip. Clay ground moves as it dries and wets, and the dry summer of 2026, when Bristol Water brought in a hosepipe ban, is the kind of year when that movement shows.

Cracks and fractures. Old clay is brittle. Heavy vehicles on a driveway, a new patio or nearby building work can crack it.

Scale and debris in cast iron. Where old cast iron runs from a soil stack into the ground, rust and crust narrow the pipe. Our guide on soil stack replacement covers the vertical part.

Pitch fibre pipes. Some homes built or extended from the 1950s to the 1970s used pitch fibre drains. They can blister and deform over time. A camera shows the pipe going oval.

Whose drain is it?

A survey often settles who has to pay. Wessex Water is responsible for public sewers and most shared pipes. You are responsible for the pipes that serve only your home, up to the boundary or where they join a shared pipe.

In a converted Redland villa with three or four flats, one drain often serves all of them. That makes it a shared drain. Since 2011, most shared private drains connected to the public network in England became the water company’s responsibility. A camera survey that shows where the flats’ pipes join is useful evidence.

You can request sewer records from Wessex Water to compare with what the camera finds.

What you get in the report

A good report should include:

• A plan or sketch of the drain runs, with chamber positions.
• The length surveyed and the pipe size and material.
• Each defect, with distance from the chamber and a still image.
• A recording of the survey.
• Plain advice on what needs doing and what can wait.

Ask whether the survey follows a recognised coding standard. That makes it easier for an insurer, a buyer’s solicitor or Wessex Water to read.

What happens on the day

1. Find and lift the inspection chambers.
2. Clear any blockage so the camera can see.
3. Run the camera from each chamber in turn, recording as it goes.
4. Note any section that cannot be reached and why.
5. Talk you through the findings before leaving.

If there is no chamber, the camera can sometimes go in through a gully or a removed toilet. That is slower and is noted in the report.

After the survey

Common next steps include:

• Jetting to remove roots and scale.
• Patch lining, where a short liner is set inside a cracked section without digging.
• Excavation and replacement for a collapsed or badly displaced pipe.
• No work, just a note to keep an eye on a minor defect.

If the survey points to a leak in the water supply rather than the drain, our guide to Bristol Water leaks explains what happens next.

Insurance

Some home insurance policies cover accidental damage to underground pipes. Insurers often ask for a survey report as evidence. Check your policy before booking repairs.

What affects the price

We do not publish fixed prices. The price is confirmed after a look at the job. It depends on the length of drain to survey, how many chambers there are, whether the drain needs clearing first, and whether you need a written report for a sale or a claim.
