Top 5 issues with clay pipes

Most cities in Australia at one point used clay piping. Whilst at the time that was the standard plumbing pipe, these days we have other better options such as PVC. A lot of older style homes with older pipes have been replaced but there are still a number of properties that are using the clay style piping.

In this post, we are going to cover the top 5 issues with clay pipes and in the end, how to fix them.

Whether you have bought a home that has old style piping or are planning to build a home on top of pre-existing clay piping, this post is for you.

Top 5 Issues with Clay Pipes


Whilst this isn't a problem for everyone a plumber will tell you that they don't like having to move clay pipes. They are ridiculously heavy and are very hard to transport. Unlike its PVC equivalent which weighs next to nothing when in comparison.

Difficult to work with

Not only are clay pipes super heavy they are also really fragile. With being so fragile is makes them very difficult to work with. Often requiring very careful attention to detail and alternative measures of repair. They can be quite costly to fix and replace compared to PVC

Root intrusions

Clay pipes don't quite fit together and as a result, it leaves small gaps in the joins between the pipes. These gaps are all a tree root needs to be able to intrude into the pipe. Once in the pipe it grows and turns into a blockage which requires alot of labour to fix.

Root Instrusions

Tensile strength

Clay pipes are extremely strong under pressure, however, their tensile strength is anything but. They are prone to cracking and shattering under blunt impacts or ground movements. These cracks cause leaks an even serious bursting which is a massive issue to the homeowner and surrounding neighbours.

Scale and flaking

Over time clay pipes will develop small chips and scale which causes the pipe to flake. These can then catch things such as hair or toilet paper. Eventually if left without treatment the pipe will become blocked from all of the debris that has been caught by that original flake.

Main fix

It is advised where possible that if you can replace your clay pipes with PVC you will be a lot happier later as you will not suffer from many of the problems listed about.
