Tree roots grow through pipe joints to block your sewer.

Todays post is very simple!

In 98% of blocked drains caused by tree roots, the roots grow through the pipe joints to get into your sewer line.

The rarely enter the pipeline through the pipes themselves.

Older sewers made of terracotta or earthenware pipes usually 600-900mm (2-3foot) long, have sand cement joints and it’s through these joints that the roots grow.

Imagine this, a 40 metre or 120 foot sewer line, with bends, junctions and fittings will have at least 40 joints.

Each pipe joint is a potential point of entry for tree roots.

Once they grow into the pipeline seeking moisture and all those nutrients, they just keep growing!

During repairs or renovations to sewers, where new PVC pipeline sections have been inserted into the old earthenware lines and joined by sand cement or rubber adaptors, its only a matter of time before the tree roots grow into these pipe joints and cause a new tree root blockage.
