Responsibility for sewer pipes

Did you know homeowners are responsible for their sewer pipes up to and including where they meet the Sydney Water sewer mains?

A lot of people are shocked to find out this piece of information.

If you need to renew your sewer pipe line because it has been damaged by tree roots and those pipes are out in the middle the road, then the homeowner is responsible for all costs associated with that renewal, including Council road opening fees.

How do tree roots get into pipes? #2

In my last post I described how tree roots can easily travel through the soil loosened by excavation for your pipe installation.

Do you know why tree roots grow in sewer pipes from the top of the pipe joints?

Condensation is formed when we run water from our water pipes, through our drains.

Especially when we have a hot shower, wash our clothes or dishes in hot or warm water.
When the warm water enters the drains buried in the cold earth, condensation is formed, and it gathers on the inside top of our sewer pipes and drains.

The tree roots moving through our already loosened soils can now move along the top of the pipelines and are attracted to the warmth and moisture inside.
All they need now is a way into the pipe.

This 1.58sec clip shows how.

How do tree roots get into pipes?

Tree roots grow through trenches dug for plumbing pipes.

When plumbers excavate a trench in virgin soil to lay our pipelines to take the waste water from your home, we till the soil.

The simple method of excavating the soil with a shovel or even a mechanical excavator like a backhoe actually breaks up the soil.

See the tree in our attached pic?

Its root system will be able to grow through the trench looking for weakness in the pipe line.

After we complete our excavations and lay the pipes in the trenches, we back fill the trench, putting the excavated soils back.

Sometimes we water in the soil and quite often use a compactor to help with the back fill process.

Excavations are often back filled with an aggregate like blue metal gravel.

The back filled trench is never as compact as the virgin soil.

It provides the roots of nearby trees a much easier path to “wander” along in their search for water and nutrients.

Do tree roots grow in PVC pipes?

Do tree roots grow in PVC pipe?
Yes they do!
The PVC pipe shown here in this Youtube clip has tree roots growing in through the wall of the pipe in three different places.
There is a significant Norfolk pine tree and a Paperbark tree within two-three metres of the pipe.
The roots were cut from this pipeline about 8 weeks ago.
This survey was taken before applying Vaporooter to the pipe line.
Vaporooter will NOT fix a broken pipe.
Vaporooter stops tree roots in drains!
In this case, we are only keeping the roots at bay until the necessary repairs are undertaken.
