Trees and shrubs look harmless next to a drain run. Yet Yorkshire Water lists tree roots among the things that can damage sewers as they grow. The same goes for the pipes on your own property.
A root problem rarely fixes itself. It tends to return after each clear-out. This guide covers the warning signs, how a survey confirms the cause and the repair options available.
How roots end up in a drain
A root needs a way in. A drain that is sound and sealed gives it little to work with. A cracked pipe or a joint that has slipped out of line gives it more.
Once a root gets inside, it can narrow the pipe. A thicker root can also distort the pipe itself. As a result, a blockage can keep coming back.
This is why the cause matters. Clearing the water does not remove the way in. In practice, the fix has two parts: deal with the roots, then deal with the opening.
Signs that roots may be the cause
No single sign proves roots are to blame. However, some patterns point towards a drain problem rather than a one-off blockage. A guide from a drainage contractor lists these:
- A blockage that returns within weeks or months of being cleared.
- Several fixtures slowing down or backing up at the same time.
- Water backing up into sinks, baths or toilets.
- Gullies that overflow, or damp patches and sewage smells outdoors.
Slow drains and gurgling can also appear early on. Because many problems cause these, it is worth looking at the wider picture. For example, one slow basin usually points to a local blockage. Trouble across the whole house points to the main drain.
Yorkshire Water gives a similar rule of thumb. If only one room is affected, the blockage is almost certainly in your own pipes. If neighbours have the same trouble, the problem is probably in the public sewer.
Who is responsible for the drain
Ownership affects who should act. Citizens Advice says you are responsible for private drains inside your property boundary. Your water or sewerage company is usually responsible for lateral drains and public sewers.
Not every case is clear. Citizens Advice says you can check with your sewerage company, your deeds, or a sewer map. The company must provide the map on request. If you are unsure, check before you pay for work.
Yorkshire Water also warns you never to try to unblock a sewer yourself. It says this risks your safety and could make things worse.
How a CCTV survey confirms roots
A camera survey is the standard way to see what is happening inside the pipe. A waterproof camera travels along the drain and records what it finds. It does not clear anything. It shows the cause.
A survey can identify cracks, offset joints and root ingress. It also gives you a visual record. That record helps when you compare quotes or need to speak to a neighbour or a water company.
You can read more about this step on our page for drain repairs. Surveys are most useful after repeat blockages. They also help when you suspect hidden damage, or before work that affects your drains.
Repair options in general terms
The right repair depends on what the camera shows. There are three broad routes.
**Jetting or cutting.** High-pressure water, sometimes with a root-cutting nozzle, can remove early root growth. It can also clear the pipe. However, roots regrow unless the entry point is sealed. Jetting alone suits light cases. Thicker roots that have deformed the pipe need a longer-term repair.
**Relining.** A resin liner is fitted inside the pipe to seal cracks and joints. Contractor guidance says it can repair misaligned joints, cracks and holes. It can also help with partly collapsed drains. Our page on pipe relining service explains the process. A final survey then checks the result.
**Excavation.** If a section has collapsed, digging up and replacing it is usually needed. Our page on drain excavation service covers this option.
A survey should come first in every case. Jetting a damaged pipe without a look inside can push debris into weak sections.
Help in Cottingham and Beverley
If trees or shrubs grow near your drains, a closer look can save repeat call-outs. If you live nearby, see our page on drain repairs in Cottingham. In addition, you can read about blocked drains in Beverley if the trouble is a recurring blockage.
Next steps
If your drain keeps blocking, do not wait for the next backup. Ask for a survey so you can see the cause. Then choose a repair that fits what the camera shows.
Request a quote online and tell us which fixtures are affected. Mention how often the blockage returns and whether neighbours have the same trouble. That detail helps us understand the problem before we visit. It also helps you decide who should act first, you or your water company.
