Why roots love clay pipe

Older sewers are earthenware pipe in short lengths. As Hampton Park's clay soil swells and shrinks, the joints shift and open. Sewer pipes carry warm, nutrient-rich water, and roots find the tiniest gap, then grow into a dense mat inside the pipe.

Warning signs

Slow drains throughout the house, gurgling toilets, a wet patch or smell near the sewer line, and the overflow gully outside spilling are all signs.

Clearing and fixing

A jetter cuts the roots out and flushes the pipe. A camera shows where they are entering. If the pipe is otherwise sound, regular jetting may be enough. If joints are broken or roots return quickly, replacing the damaged section or relining the pipe stops them permanently.

Planting near sewers

Keep large trees and shrubs with aggressive roots, such as willows, figs, poplars and some gums, well away from sewer lines. We can locate your sewer line before you plant. Roots grow fastest in spring and summer, so blockages often appear then. Ask us to mark the sewer path before planting.

Hampton Park soil and pipes

Hampton Park sits on heavy grey clay over sandier ground towards Lyndhurst, and that clay swells in a wet winter and shrinks and cracks in a dry summer. The older homes west of Hallam Road were mostly connected with earthenware sewer pipe in short lengths, and every joint is a place for roots to get in once the ground moves. Galvanised steel water pipe from the same era rusts from the inside, narrowing the bore and eventually leaking. On the newer estates, PVC drains are tougher, but trenches that were not compacted properly can settle and leave dips that hold grease and paper. We use a drain camera and pressure testing to see what is actually happening rather than guessing.

Questions on this topic

Will root killer fix it?

It may slow regrowth but does not repair the pipe. Relining or replacement is the lasting fix.

How often should roots be cleared?

If you choose not to repair, every one to two years is typical.
