“When it comes to plumbing, the type of pipes used in a house can affect the overall efficiency, safety, and cost of the plumbing system. Understanding what type of plumbing your house has can help you make informed decisions about maintenance, repairs, and upgrades.” said Dean Owens of Plumber Warragul.
In this article, we will explore the most common types of plumbing found in houses and their advantages and disadvantages.

Most houses in Australia have a plumbing system that consists of a network of pipes that supply water, remove sewage and wastewater, and provide gas for appliances.
The water supply system is usually made up of copper pipes, which are durable, corrosion-resistant, and easy to install. Copper pipes are also great for hot water systems, as they can withstand high temperatures.
Sewage and wastewater are typically removed through a drainage system that uses PVC pipes. PVC pipes are lightweight, affordable, and resistant to chemicals and corrosion.
Gas supply systems are also common in houses, and they use pipes made of materials such as copper, steel, or plastic.
Copper pipes are the most popular choice for gas supply systems, as they are durable and resistant to corrosion. Steel pipes are also used for gas supply systems, but they are more prone to corrosion and require regular maintenance.
Plastic pipes are not recommended for gas supply systems, as they can degrade over time and leak gas.
Types of Plumbing Pipes
When it comes to plumbing pipes, there are two main types: metal pipes and plastic pipes. Each type has its own advantages and disadvantages, so it’s important to understand the differences before deciding which type to use in your home.
Metal Pipes
Metal pipes, such as copper and galvanized steel, have been used for plumbing for many years.
Copper pipes are known for their durability and corrosion resistance, making them a popular choice for water pipes.
Galvanized steel pipes are also durable and are often used for outdoor plumbing.
However, metal pipes can be more expensive and difficult to install than plastic pipes. They are also less flexible, which can make them harder to work with in tight spaces.
Rigid copper pipes, for example, require specialized tools to bend and shape.
Plastic Pipes
Plastic pipes, such as PVC, ABS, PEX, and CPVC, have become increasingly popular in recent years.
They are lightweight and flexible, making them easy to install and work with. Plastic pipes are also more affordable than metal pipes, making them a cost-effective choice for many homeowners.
PVC pipes are commonly used for drainage and waste systems, while PEX pipes are best for supply lines for hot and cold water in homes.
ABS pipes are also used for drainage systems, while CPVC pipes are often used for hot water supply lines.
One of the main advantages of plastic pipes is their resistance to corrosion. Unlike metal pipes, plastic pipes do not rust or corrode over time. However, they may not be as durable as metal pipes and may have a shorter lifespan.
Plumbing System Applications
Water Supply and Drainage
The plumbing system in most houses consists of two main systems: the water supply system and the drainage system.
The water supply system provides potable water to the house, while the drainage system removes wastewater from the house.
The water supply system is responsible for delivering hot and cold water to all the sinks, toilets, and showers in the house.
The water supply lines are made of different materials, including copper, PEX, and PVC.
Copper pipes are durable, long-lasting, and resistant to corrosion, making them the most commonly used type of internal plumbing in Australia.
PEX pipes are also popular in Australia because they are flexible, easy to install, and affordable. PVC pipes are often used for drain and vent systems, but they can also be used for water supply lines.
It is important to ensure that the water supply system is installed in compliance with local building codes.
Local building codes dictate the layout of the water supply lines, the materials used, and the installation requirements.
It is recommended to hire a professional plumber or contractor to install the water supply system to ensure that it is installed correctly and in compliance with local building codes.
The drainage system is responsible for removing wastewater from the house.
Drain lines are connected to sinks, toilets, and other plumbing fixtures and are designed to carry wastewater to the sewer or septic system.
The drainage system must be installed to ensure that there are no leaks or blockages that could cause sewer gases to enter the house.
Specialised Systems
In addition to the water supply and drainage systems, there are also specialised plumbing systems that are designed for specific applications.
For example, hydronic heating systems and radiant floor heating systems use copper pipes to circulate hot water through the house to provide heat. Meanwhile, irrigation systems use PVC pipes to deliver water to the garden or lawn.
It is important to ensure that specialised plumbing systems are installed correctly and in compliance with local building codes. To do this, you should hire a professional plumber or contractor like Plumber Warragul who has experience in installing specialised plumbing systems.
