Blocked drain symptoms tell you where to start, but recurring faults need evidence. Restore safe flow first, then use CCTV and locating when roots or pipe damage may change the repair decision.
Why roots enter drainage pipes
Roots are attracted to moisture around leaking joints and cracks. Once small roots enter, they grow inside the pipe and catch paper, waste and sediment.
Symptoms of a root blockage
Flow may slow gradually, the same line may block repeatedly and jetting may bring out fine or heavy root material. CCTV provides the clearest confirmation.
How roots are removed
A specialist jetter with a root-cutting nozzle can break up and flush many root masses. The method is chosen to suit the pipe and access.
Why cutting roots may be temporary
If the crack or joint remains open, roots can return. The next step is to locate the entry point and decide whether relining or excavation is suitable.
Do you need to remove the tree?
Not necessarily. Drain repair and vegetation decisions depend on the location, tree, pipe route and extent of damage. Diagnose the pipe first.
