Your Local Blocked Drain Plumber in Gymea

One issue dominates almost every call-out we get around here.

Tree roots in the pipes. Established post-war streets with mature trees, backing onto bushland reserves like Coongong Creek, send roots straight into the joints of the area's ageing clay sewer lines, and once they're in, the blockage keeps returning until the line itself is fixed.

That's different from a one-off blockage from something flushed or washed down the drain; root intrusion is a structural problem in the pipe, not just debris passing through.

Coongong Creek Bushland Reserve runs through part of the suburb, and the streets that back onto it carry a heavier root load in their sewer lines than blocks further from the bushland edge.

Established fig and gum trees planted along the older post-war streets add to that, since a mature root system reaches well beyond the tree's own block boundary looking for moisture.

A pipe running under a nature strip lined with 60-year-old trees is doing exactly the kind of job that finds every crack in an old clay joint, and it usually finds it more than once.

That's why a property near the reserve or on one of the older tree-lined streets is more likely to see a repeat call-out than a newer unit near the station, where the trees, and the pipes, are both younger.

Cutting the roots back with a hydro jet clears the immediate blockage, but it doesn't stop them growing back into the same crack given enough time.

For a repeat offender, relining the affected section is usually the fix that actually holds, since it seals the crack the roots were using rather than just clearing what's grown through it.
