Many people ask whether they need their drain jetted or relined. The two jobs sound alike, but they do different things. One clears the pipe. The other repairs it.
Choosing the wrong one wastes money and time. This guide explains what each method does, what it cannot fix and why a survey should come first.
What jetting does
Jetting uses high-pressure water. A forward jet breaks up the blockage. Rear jets pull the hose along and flush the debris out. One contractor guide says it works well on grease, hair, soap residue, limescale and general sludge. It also works on silt in surface water drains.
Jetting scours the pipe walls too. As a result, it can remove the residue behind recurring slow drainage, not just the blockage itself. For many homes, that is all the drain needs.
Our page on domestic drain jetting explains how the work goes on a home drain.
What jetting does not fix
Jetting cleans. It does not mend. The same guide says it cannot reopen a collapsed or deformed pipe. It also cannot repair the weakness in an older pipe that is failing.
Roots are a good example. Jetting can cut them back, but they regrow unless the entry point is sealed. Jetting a damaged pipe without a look inside can also push debris into weak sections.
In practice, a blockage that keeps returning is the main warning. If a drain blocks again within weeks or months, the cause is probably still there.
What relining does
Relining is a no-dig repair. A resin-coated liner is fitted inside the damaged pipe and left to cure. Contractor guidance says it can repair misaligned joints, cracks and holes. It can also help with partly collapsed drains.
The process usually follows set steps. A camera survey finds the fault. Jetting then clears loose debris. After the liner cures, a second survey checks the result.
Because the work is done from inside, it usually means less digging. You can read more on our pipe relining service page. However, it will not suit every drain. The survey decides that.
When digging is the answer
Some faults need excavation. Contractor guidance says a collapsed section needs to be dug up and replaced. Patch repair suits isolated damage, while a pipe with several faults may need more.
Excavation is more disruptive, so it should be a decision based on evidence. The survey record gives you that evidence. Ask to see it before you agree to any dig.
Why a survey comes first
A survey does not clear anything. Instead, it shows what is wrong. The camera can identify cracks, offset joints and root ingress, and it gives you a visual record.
Surveys are recommended after repeat blockages and when you suspect a collapse. They also help before you buy an older property or start renovation work that affects the drains.
Ownership matters too. Citizens Advice says you are responsible for private drains inside your boundary. Your water or sewerage company is usually responsible for lateral drains and public sewers. Check which applies before you pay for a repair.
A simple way to decide
Start with the history of the problem. A first-time blockage, with no other signs, often suits jetting. A blockage that returns suggests a fault in the pipe. Several fixtures backing up together, or gullies that overflow, also point to a deeper problem.
Next, think about the age of the pipes. The contractor guide notes that older homes with clay or pitch fibre pipes are more likely to need a survey. For example, jetting a failing pitch fibre pipe may improve flow briefly, but it cannot fix the weakness underneath.
Finally, ask what the quote will leave you with. A clear-out leaves the pipe as it was. A repair changes the pipe. Both can be right, but you should know which one you are paying for.
Other routes to check
Before you book any work, check who else might pay or act. Yorkshire Water says renters should contact their landlord. Owners should check whether home insurance or a separate policy covers drainage. If the home is under ten years old, the developer may be responsible, because the drainage can be under warranty.
If a private drain is left in a poor state, your council can act. Citizens Advice says the environmental health team can order you to repair, replace or unblock it. If you do not comply in time, the council may do the work and charge you.

Next steps
If your drain blocks again and again, ask for a survey before you choose jetting or relining. The camera shows whether a clear-out will be enough.
