Types of Plumbing Pipes and Their Functions

The plumbing system is a vital structure in all modern homes. Functional plumbing brings clean water in for the baths and taps and carries waste and dirty water into a public sewer system. Different parts make up the system. Each plays a crucial role; the failure of a single pipe can disrupt the system’s entire operation. Good thing you can always rely on plumbing services in Auckland for help.


A plumbing specialist can educate you on how to maintain your pipes, but it’s also your responsibility to have enough knowledge of your plumbing system. This knowledge ensures you choose the appropriate pipe types and materials that best fit your budget and requirements.


This article lists the different types of plumbing pipes, their characteristics, and why you should get them.


A Quick Guide to Plumbing Pipes to Use at Home

Different types of pipes provide solutions for specific plumbing jobs. You can find pipes ideal for water supply plumbing, sewer, drainage, and other exterior functions.


Galvanised Steel Pipes

These pipes support plumbing for clean water supply lines, vent lines, and drain lines. Like cast iron pipes, you can find these in older Auckland homes. What makes galvanised still relevant today is their corrosion resistance and durability. The only catch is that these pipes are pricey compared to their plastic counterparts.


Acrylonitrile Butadiene Styrene (ABS) Pipes

One of the most modern pipes is the ABS pipe. Mainly used for drains and vent lines, these pipes are durable, cost-effective, and made from thermoplastic resin. Whilst a reliable material, extreme exposure to the sun’s heat warps and degrades ABS pipes. It’s often compared to PVC pipes; however, it’s black and a bit soft and bendy.


Polyvinyl Chloride (PVC) Pipes

Another preferred pipe for drains and vents, PVC pipes are a modern piping option known for their lightweight and flexible qualities. PVC pipes are durable, inexpensive, easy to install, and can work with galvanised steel.


Copper Pipes

Copper pipes are known for their durability and rigidity. These qualities are a result of their pure copper metal material. This pipe option is ideal for water supply lines as, unlike its plastic counterpart, copper won’t leach chemicals. However, copper pipes are on the expensive side.


PEX Pipe

PEX pipes lead the water supply plumbing system, thanks to their rigidity and durability. They are quality plastic piping and can withstand varying water pressures. They’re easy to work with, weaving through the different areas of the house, thanks to their easy cut and join characteristics. PEX pipes are colour coded. Red PEX pipes are for hot water supply, and the blue ones support cold water plumbing.


Flexi Pipe

Unlike the previously mentioned types, Flexi pipes serve as connection tubing rather than solid line pipes. They connect pipelines to appliances, sinks, and other water fixtures in the home. Since they are exposed and part of the exterior styling, they come in a clean, stainless-steel appearance. Flexi pipes can come in different lengths and sizes. They are durable and can last for years.
