Why Professional Manhole Unblocking is Critical for Liss Sites
When an external manhole overflows in Liss—whether on a private driveway in the local area or a commercial loading bay in the town center—it represents a total failure of the drainage network. Unlike internal clogs, a blocked manhole usually indicates a deep-seated obstruction in the 100mm or 150mm main lines. Liss’s historic brick-built chambers and modern plastic interceptors both face risks from root ingress, silt accumulation, and “fatbergs.” We provide the technical authority to resolve these high-volume failures. Using truck-mounted jetting units, we clear the entire sewer reach, not just the chamber, ensuring the Liss infrastructure is restored to its original hydraulic design.

Our Liss Manhole Unblock Workflow
We follow a rigorous engineering protocol to ensure your Liss sewer system is safely and permanently restored.
Hydraulic Assessment
Our Liss engineers identify the “blind” manhole and the direction of flow to determine the most effective jetting point.
High-Velocity Jetting
We deploy industrial-grade hoses from our Liss-based tankers to break down the obstruction and flush the line.
Structural Verification
Once the manhole unblocking is complete, we perform a visual or CCTV check to ensure the Liss pipe walls are intact.
