Blocked Drains

Why drains keep blocking in coastal suburbs

Coastal homes often deal with a mix of sand, tree roots, older pipework and stormwater pressure. When a drain keeps blocking, the goal is not only to clear it, but to understand why it keeps happening.

Tree roots and older pipe joints

Roots are one of the most common causes of recurring sewer and stormwater blockages. They enter through small cracks or joints and expand over time, catching paper, debris and grease.

A high-pressure jet can clear the immediate blockage, while a CCTV drain inspection can help confirm whether the pipe needs repair, relining or ongoing maintenance.

Sand, leaves and stormwater debris

Homes near the bay and foreshore can see more sand and leaf matter entering outdoor drains, pits and gutters. During heavy rain, this buildup can restrict flow and cause water to pool around paths, driveways and low points.

Regular cleaning of grates, gutters and pits helps, but repeat flooding or gurgling drains should be checked before the next storm.

Kitchen grease and everyday buildup

Grease, coffee grounds and food scraps can harden inside pipes. Even if water still drains, the pipe diameter may be narrowing over time.

Professional drain clearing removes the blockage more thoroughly than plunging alone and gives you a clearer view of whether the issue is a one-off or part of a larger drainage problem.

Frequently asked questions

Why does my drain block again after being cleared?

Common causes include tree roots, pipe damage, heavy grease buildup or a low section of pipe holding debris.

Do I need a CCTV drain inspection?

If the blockage keeps returning, a CCTV inspection can identify cracks, roots, collapsed sections or poor pipe grade.
