Blocked Drains The Gap
The Gap’s tree-lined streets are one of the suburb’s great features — and its leading cause of blocked drains. Established gum trees and fig trees have had decades to find every joint in the area’s ageing clay sewer network. TBP Plumbers The Gap clears them properly, starting with a camera inspection so we know exactly what we’re dealing with before touching a thing.
Why The Gap Has a Blocked Drain Problem — and How We Fix It
The Gap and the surrounding northwest Brisbane suburbs were largely developed from the 1960s through the 1990s. That housing stock brought with it clay and terracotta sewer lines that, decades on, are cracking, settling and being infiltrated by tree roots. The leafy, established character of the suburb is one of its best features — but the large gum trees and fig trees that give The Gap its green canopy are the same species driving the most root-intrusion calls we attend.
We camera every blocked sewer drain before touching it. In The Gap — where root intrusion from established trees is the dominant cause — clearing a blockage without diagnosing its origin gives you six months of relief at best. We show you the footage, explain what we found, quote the permanent fix, and do it once, properly.
What We Clear
Our Process
How We Unblock Drains
We diagnose before we fix. Every job starts with finding the cause — not just clearing the symptom.
CCTV Inspection
We run a camera through the pipe to locate the exact blockage and assess whether it's a build-up, root intrusion, or structural damage.
Choose the Right Method
Minor blockages are cleared with hand tools. Stubborn build-ups are cleared with high-pressure water jetting. Collapsed or root-damaged pipes are repaired or relined.
Clear & Prevent
We clear the blockage completely, confirm with a final camera check where needed, then advise on how to avoid the same issue in future.
Methods We Use
Hand Tools
For straightforward blockages close to the drain opening — hair, soap, small debris.
High-Pressure Jetting
Powerful water jetting scours the pipe walls clean and blasts through stubborn grease, roots and compacted debris.
Pipe Relining
For cracked, collapsed or severely root-damaged pipes — a no-dig solution that repairs the pipe from the inside. Learn more.
