South Coogee blocked drain: tree roots

Saturday morning emergency call from a homeowner in South Coogee. The main drain had backed up overnight, water wasn't going anywhere, and they needed it sorted before the weekend was over.

We got to the property, set up the CCTV camera, and ran it down the line. At about 22 metres in, the picture told the story: tree roots had pushed through a joint in the old clay pipe and completely blocked the bore. No water was getting past.

We switched to the high-pressure jetter with a root-cutting head, cut through the root mass, flushed the debris, and ran the camera again to confirm the line was clear. Drain flowing properly by lunchtime.

This is one of the most common jobs we do across the Eastern Suburbs. Older homes, clay pipes, established trees - the combination creates the same problem over and over.

Five signs tree roots might be blocking your drain

If you're seeing more than one of these, roots are worth investigating:

• The same drain keeps blocking. Not different drains around the house, the same one. Roots grow into a single weak point in the pipe, usually a cracked joint, and that's where the blockage happens every time.
• It gets worse after rain. Wet weather encourages root growth. If your drain runs fine through a dry stretch and then backs up after a few days of rain, that pattern points toward roots.
• Gurgling sounds when water drains. Roots inside the pipe create a partial obstruction. Water has to push past the mass, which pulls air through and produces a gurgling noise, particularly from toilets and floor wastes.
• Slow drains that drain cleaner doesn't fix. Supermarket drain cleaner dissolves grease and soap buildup. It does nothing to tree roots. If you've tried chemical solutions twice and the drain is still slow, the problem is almost certainly physical, not chemical.
• Your home predates the 1980s. Most homes built before then in Coogee, Bondi, Randwick, Maroubra, and Bronte still have their original terracotta clay drainage. The joints between sections were never designed to be permanently watertight, and decades of ground movement opens them up to root entry.

If any of this sounds familiar, a CCTV drain inspection is the quickest way to know for certain. The camera shows exactly what's happening inside the pipe, where the roots are entering, and how much of the bore is blocked. We record the footage and show it to the homeowner on the spot.
