Sewer Blockage in Tanawha: Tree Roots & Sagging Pipe 🌴​

At Blocked Busters, we’re often called out to jobs where customers believe their septic tank needs pumping out, but the real problem lies further up the sewer line. This was exactly the case with a recent job in Tanawha on the Sunshine Coast.

The Problem

The homeowners noticed that their toilets, kitchen sink, and bathrooms were all backing up and draining away very slowly. They thought the issue was a full septic tank, but after inspection, we discovered the real cause was a blocked sewer main leading to the septic tank.

Our camera inspection revealed two key problems:

• Tree root intrusion – roots had grown into the pipe and created a solid blockage.

• A sagging (belly) section of pipe – this created a dip in the line, allowing waste and water to build up over time.

How We Fixed It

We used our high-pressure water jetter to clear out the blockage quickly and restore flow to the system. Once cleared, we carried out a full CCTV drain inspection to assess the overall condition of the line.

This inspection confirmed both the tree root intrusion and the sagging section of pipe. We explained everything clearly to the customer, showing them the footage so they could see exactly what was happening underground.

The Next Step

While the immediate blockage was resolved, the long-term solution is to repair the damaged section of sewer line. We’ll be returning to carry out the necessary pipe repairs to ensure the problem doesn’t reoccur and the system runs smoothly for years to come.

Why This Matters

It’s a common misconception that slow or overflowing systems on properties with septic tanks always mean the tank needs pumping. In many cases, the real issue lies in the sewer pipes. That’s why professional diagnosis with jetting and camera inspections is essential—it saves homeowners unnecessary costs and ensures the root cause is properly addressed.
