What causes tree roots in drains?

What it could mean

Understand the symptoms.

Roots may enter drainage through defects or joints where moisture is available. Removing roots alone does not repair a damaged pipe.

What to do next

A camera inspection can help assess whether ongoing cleaning or structural repair deserves consideration.

When a plumber should assess it

If the fault continues, is affecting other fixtures, risks damage or cannot be identified safely, arrange a professional assessment. Similar symptoms can have different causes, so an inspection is needed before confirming a repair.

What to tell us

• Your suburb and the affected fixture or system
• Whether the problem is continuous or intermittent
• Any noises, visible leaks, odours or recent changes
• Whether it involves a single fixture or several

This article is general guidance. Do not attempt electrical, gas, pressurised, confined-space or unsafe drainage work.
